Highlights of Solar and Geomagnetic Activity 24 - 30 July 2017
Solar activity was very low throughout the summary period. A B1
flare, observed at 27/2136 UTC from a plage region near center disk,
was the strongest event of the period. Region 2668 (N03, L=311,
class/area Axx/010 on 25 Jul) decayed to plage by 26 Jul and Region
2669 (N18, L=255, class/area Axx/010 on 30 Jul) remained inactive.
No Earth-directed CMEs were observed in available coronagraph
imagery.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at
normal to high levels on 26 Jul, high levels on 30 Jul and moderate
to high levels throughout the remaining days of the period. A
maximum flux of 18,800 pfu was observed at 25/1515 UTC. The
enhancements in flux levels were due to persistently elevated solar
winds from a slowly-waning, positive polarity CH HSS.
Geomagnetic field activity ranged from quiet to active levels over
the past week. Quiet to active levels were observed on 24 Jul and 26
July; quiet to unsettled levels were observed on 25 Jul and 27-28
Jul; the remaining days were quiet. Geomagnetic activity was
associated with the influence of a slowly-waning, positive polarity
CH HSS enhancing solar wind speeds. A steady decline in wind speed
was observed over the entire reporting period from a peak speed of
705 km/s at 24/2219 UTC to a low of around 350 km/s by the end of 30
Jul.
FORECAST OF SOLAR AND GEOMAGNETIC ACTIVITY 31 JULY - 26 AUGUST 2017
Solar activity is expected to be at low levels with a chance for
M-class flare (R1-R2/Minor-Moderate) on 31 Jul - 13 Aug due to the
return of old Region 2665 (S06, L=113) rotating across the visible
disk. The remainder of the outlook period is expected to be at very
low levels.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is
expected to range from normal background to high levels. High levels
are expected on 01-03 Aug, 05-10 Aug, and 18-26 Aug; moderate levels
are expected 31 Jul and 11 Aug; normal background levels are
expected for 04 Aug and 12-17 Aug. All enhancements in electron flux
are due to multiple anticipated recurrent CH HSSs.
Geomagnetic field activity is expected to range from quiet to G1
(Minor) geomagnetic storm levels. G1 (Minor) storm levels are likely
on 04-05 Aug and again on 17-18 Aug; active conditions are likely on
31 Jul, 06 Aug and 19 Aug; unsettled levels are likely on 01-02 Aug,
07 Aug and 20-21 Aug; quiet conditions are expected for the
remaining days of the outlook period. All anticipated enhancements
in geomagnetic activity are due to multiple, recurrent CH HSSs.

Glenn Hauser logs July 31, 2017
** EQUATORIAL GUINEA. 5005, July 31 at 0546, JBA carrier from presumed Bata RNGE; while 6250 is still gone from Malabo. Having proved that transmitter is working, they`ve turned it off again, or it broke down again. We`ll all be keeping an ear on 6250 a while longer (Glenn Hauser, OK, DX LISTENING DIGEST)
** MALI. 5995, July 31 at 0648, ORTM is axually modulated as some fix has been done to this long almost inaudible unit; fair signal but splash from 6000 RHC which unfortunately is not undermodulated for a change (Glenn Hauser, OK, DX LISTENING DIGEST)
** NEW ZEALAND. 9630, July 31 at 0550, RNZI on new frequency ex-9700, S9+10 and seems clear altho confronting a local device blubbler here, my problem (Glenn Hauser, OK, DX LISTENING DIGEST)
** PUERTO RICO. 5125, July 31 at 0059, very strong carrier with tone tests on again tonight, from presumed Arecibo radiotelescope experimenting with ionospheric heating. Last night the tones were in steps, but tonight they are sweeps up and down in pitch, and between them the carrier cuts off briefly. These can be heard all the way between 5113 and 5145, weakening toward the edges, and of course, blotting out the very weak signal from WBCQ 5129.82-AM. Still the same past 0107 and 0121. Next check at 0219-0221 nothing heard, but WBCQ is still too weak in storm noise level.
After 0300, when WORLD OF RADIO is on WBCQ, the 5125 signal is back on, but weakened, now with tones stepping upward causing weak hets to very poor WBCQ. By 0332, 5125 is S9+30 fading to only S9, and cutting on and off without tones at the moment. At 0434 off; at 0545 open carrier back on. At 0650 final check, still weakened unmodulated carrier. July 31 is supposed to be the final date for this week-long experiment, so unclear whether it will be on again for UT August 1 (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A [and non]. WORLD OF RADIO 1888 monitoring:

-- 73! (Ivo Ivanov, QTH: Sofia, Bulgaria, Equipment: Sony ICF-2001D 30 m long wire, dxldyg via DX LISTENING DIGEST) Theme recognizable, not readable but improving in first sesquiminute (gh)
Also confirmed Sunday July 30 at 2330 on WBCQ, 9330.2v-CUSB, fair. Also confirmed UT Monday July 31 from 0300 on Area 51 webcast (a few seconds of the 0330 program cued up, Hobart Radio International started by mistake, quickly cut to WOR); while WBCQ 5129.8-AM is very weak, and obliterated by tone tests from huge 5125 transmitter, presumed to be ionospheric heating experiments from Arecibo, Puerto Rico, oblivious of the US SW station nearby. Also confirmed UT Monday July 31 at 0330 on WRMI, 9955, fair. Next:
Mon 2330 WBCQ 9330v-CUSB to WSW
Tue 0030 WRMI 7730 to WNW
Remember that new 1889 should start Tuesday at 2130 on 9455 & 15770; or if I am delayed, maybe at 2330 on 9330 (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. 9455, July 31 at 1321, WRMI is back to Oldies here instead of duplicating 9395 with `The Power Hour`. But when I tune in at 1321, it`s VOA news relay at odd time, soon followed by Biermann`s WRMI ID and ``Something Happened`` -- indeed; while TPH is in a 4-minute ad break. Nice of them to warn listeners how long they may safely tune out. 9395 is still // weaker 7780 WRMI, and stronger 13845 WWCR which is ahead by about a semiminute. At 1424 check, still music on 9455, TPH on 9395 // 7780, both very poor (Glenn Hauser, OK, DX LISTENING DIGEST)

Global Daily HF Radio Wave Propagation Forecast-
HF radio wave propagation conditions are improving.
HAMATEUR & SW BROADCAST HF BANDS-
80-60 (75-60) meters- poor at night and very poor at day,
40-30 (41-25) meters- fair at night and poor at day,
20-17 (22-15) meters- fair at night and fair at day,
15 (13) meters- poor at night and fair at day,
12(11) meters- very poor at night and poor to fair at day.
10 (11) meters- very poor at night and poor at day.
Keep in mind that almost daily during the northern hemisphere summer season you will find that the 10 (11) meter bands will open via short north-south and east-west propagation paths via sporadic E (Es). Also when multiple sporadic E (Es) clouds form and line up favorably much longer propagation paths open up on east-west paths. And last but not least north-south propagation paths occur across the equator via trans equatorial propagation (TEP).
SOUTHERN HEMISPHERE RADIO WAVE PROPAGATION-
80-60 (75-60) meters- good at night and poor at day,
40-30 (41-25) meters- good at night and fair at day,
20-17 (22-15) meters- very poor at night and good at day,
15 (13) meters- very poor at night and fair to good at day,
12 (11) meters- very poor at night and fair at day.
10 (11) meters- very poor at night and poor at day.
Received RF signal strength scale-
Very Good- +1 over S9 Or Greater
Good- S7-9
Fair- S4-6
Poor- S1-3
Very Poor- S0
Meter Band Equivalents
Ham & SWL
160-> 90
80-> 75
60-> 60
40-> 49, 41
30-> 31, 25
20-> 22, 19
17-> 16, 15
15-> 13
12,10-> 11
We are now firmly in summer/winter solstice type of HF radio wave propagation conditions.
This means generally poor HF radio wave propagation conditions in the northern hemisphere especially at day and generally good HF radio wave propagation conditions in the southern hemisphere especially at day.
Globally HF radio wave propagation conditions are most evenly balanced
during the fall and spring equinoxes and most diametrically opposed during
the summer and winter solstice.
Conditions change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the
ecliptic, as well as by radio wave frequency. This is due to changes in the
maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2).
---------------------------------------------------------------------------------------------------------------------
This HF Radio wave propagation forecast is produced based on the NSA_CAP HF radio wave propagation prediction software. I wrote it beginning in the late 1980’s but I’m sorry to say that it can’t be distributed to the public.
And though this HF radio wave propagation forecast is produced based on the NSA_CAP, I do check the actual band conditions at my location in the state of Florida USA and tweak the forecast manually where and when necessary. And I also check global HF radio wave propagation conditions via remoted radio receivers around on every continent of the globe and tweak if and when necessary.
The hamateur radio JT65A mode RF signal levels received are based on 5 watts and ½ wave dipole up at 40 feet.
The hamateur radio PSK31 mode RF signal levels received are based on 25 watts and ½ wave dipole up at 40 feet.
The hamateur radio CW mode RF signal levels received are based on 50 watts and ½ wave dipole up at 40 feet.
The hamateur radio SSB RF mode signal levels received are based on 100 watts and ½ wave dipole up at 40 feet.
The HF shortwave broadcast band AM Mode RF signal levels are based on 100,000 watts (100 kw) and a typical VOA type curtain array antenna.
Please keep in mind that this is a relatively simplified HF radio wave
propagation forecast, so as to keep it easily understandable and applicable by the average radio enthusiast.
Globally HF radio wave propagation conditions are most evenly balanced
during the fall and spring equinoxes and most diametrically opposed during
the summer and winter solstices.
Conditions change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the
ecliptic, as well as by radio wave frequency. This is due to changes in the
maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2).
The D and E layers also come into play through RF radio wave signal
absorption and refraction. And then there is sporadic E (Es) radio wave
propagation that can really throw a wrench into the gears so to speak.
Things like sporadic E (Es) radio wave propagation and lightning storm
static can impact HF radio wave propagation in an unpredictable manner and
mostly bad.
Ongoing solar, space and geomagnetic weather goings on also impact HF radio
wave propagation conditions in a negative manner.
---------------------------------------------------------------------------------------------
Solar, Space & Geomagnetic Weather Conditions On
Sunday July 30, 2017-
Solar activity very low.
Earth's geomagnetic field was at a quiet level.
The three daily solar flux index (SFI) numbers were 69.4 69.5 69.5.
Considering that solar minimum won't occur for approximately 2 more years,
+/- 1 year, the daily < 70 solar flux numbers are occurring unusually early.
The official daily sunspot number (SSN) was 11.
But on Monday July 31, 2017 unofficially (determined by me) the daily sunspot number (SSN) was 0.
In 2017 officially there were 55 days with a daily sunspot number (SSN) of
0.
Considering that solar minimum won't occur for approximately 2 more years,
+/- 1 year, daily SSN's of 0 are occurring now unusually early.
In 2016 officially there were 32 days with a daily sunspot number (SSN) of
0. Considering that solar minimum won't occur for approximately three more
years, seeing daily SSN's of 0 occurring now is unusually early.
As we move forward towards the next solar minimum between solar cycle #24
and #25 the number of days with a 0 daily SSN will steadily increase.
Eventually every day for many, many, many months will see a 0, the big goose
egg.
In 2008 I forecasted solar cycle 24 to be the weakest in the past 100 years
and that forecast verified. I also forecasted that solar cycle 25 would be
virtually nonexistent, similar to the Dalton type solar minimum that
occurred in the early 1800's. Other than sunspot magnetic polarity it will probably be very difficult to determine when solar cycle 24 ended and solar cycle 25 began.
---------------------------------------------------------------------------------------------------------------------
There was 1 newly risen and/or emerged and/or existing earth facing official sun spot group (SSG).
Existing sunspot group (SSG) #12669 located near N18W36 with a simple alpha magnetic signature.
Continued active far side recurrent (which means that it has faced earth during the previous rotation of the sun and will again) sunspot group #2665 will rise above the east limb of the sun beginning on approximately Monday July 31, 2017. It could wreak havoc on earths geomagnetic field in the form of solar flares, coronal mass ejections (CME), solar fade outs, energetic proton storms and geomagnetic storming.
There was 2 unofficial and as of yet unnumbered earth facing sunspot groups (SSG) located near
N05W10,
N07E33.
There was no small in size C class or larger solar flare.
No earth facing coronal mass ejection (CME) related high latitude energetic proton storm occurred (polar cap absorption).
No solar flare related x-ray day side solar fade out (SFO) occurred.
--------------------------------------------------------------------------------------------------------------------
There was no earth facing coronal mass ejection (CME).
There was no earth facing collapsing magnetic filament eruption.
The 24 hour period 3 hour interval planetary K index (Kp) was at quiet geomagnetic conditions of
1 1 1 1 0 1 1 0.
The Kp geomagnetic indices are-
0-2- quiet
3- unsettled
4- active
5- minor geomagnetic storming
6- moderate
7- strong
8- severe
9- extreme
10- our atmosphere just got cooked off like on Mars and we are all dead.
The 24 hour period maximum and minimum planetary A index (Ap) ranged between
5 and 0,
which was at quiet geomagnetic conditions.
The Ap geomagnetic indices are-
0-7- quiet
8-15 unsettled
16-29- active
30-49- minor geomagnetic storm
50-99- major
100-400- severe
>401- our atmosphere just got cooked off like on Mars and we are all dead.
The 24 hour period averaged energetic proton flux was at a background level below 10 MeV.
The 24 hour period averaged background x-ray flux was at B9.21.
The 24 hour period averaged vertical component (Bz) of earth's geomagnetic magnetic field was at
-1.15 nT south.
The 24 hour period maximum and minimum disturbance storm time index (Dst) ranged between
-9 and +9 nT.
The 24 hour period maximum and minimum solar wind speed ranged between
381 and 289 km/s.
There was an earth facing southern hemisphere coronal hole (CH) #817.
It’s associated high speed solar wind stream (HSS) could wreak havoc on earth’s geomagnetic field in the form of minor geomagnetic storming conditions in approximately 1 more day.
There was a recently emerged earth facing northern hemisphere coronal hole (CH) #818.

GENERAL GUIDELINES CONCERNING CORRELATION OF PROPAGATION INDICES TO ACTUAL HF PROPAGATION CONDITIONS-
NOTE!!! The propagation indices "interpretations" are my personal
intellectual property. Therefore the radio wave propagation indices
interpretations contained herein is copyrighted © 1988-2017 by Thomas F.
Giella, W4HM, all rights reserved. Reproduction of information herein is
allowed without permission in advance as long as proper credit is given.
All 14 of the following indices have to occur as described below in order to
see the best global high frequency radio wave propagation possible,
something that happens rarely.
1.) Dropping geomagnetic field indices numbers are better, Kp of 0 best.
2.) A daily sunspot number of 150 or higher, 200 or higher best.
3.) A daily sunspot number of greater than 100 for routine stable formation
of the E Valley/F Layer ducting mechanism.
4.) Previous 24 hour Ap index under 10, fewer than 7 for several days
consecutively are best.
5.) Previous 3 hours Kp index fewer than 3 for mid latitude paths, fewer
than 2 for high latitude paths, 0 for several days consecutively is best.
6.) Energetic protons no greater than 10 MeV (10+0).
7.) Background x-ray flux levels greater than B1 for several days
consecutively, greater than C1 best.
8.) No current STRATWARM alert.
9.) Interplanetary magnetic field (IMF) Bz with a (positive number) sign,
indicates a lesser chance of high latitude path aurora
absorption/unpredictable refraction or scattering of medium frequency RF
signals, when the Kp is above 3.
10.) A -10 or better towards a positive number Dst index during the recovery
time after a geomagnetic storm, as related to the equatorial ring current. A
positive number is best.
11.) Rising positive T index number. The T Index tracks with the F2 layer
critical frequency (foF2) and sunspot number (SSN) and indicates the
capability of the F2 layer to refract RF signals.
12.) Galactic cosmic rays decrease to -3 units below zero and trending
towards zero.
13.) Energetic electron flux levels no greater than 2 MeV (2+0).
14. A solar wind speed of less than 300 km/s for several days consecutively.

Global Daily HF Radio Wave Propagation Forecast-
HF radio wave propagation conditions are improving.
HAMATEUR & SW BROADCAST HF BANDS-
80-60 (75-60) meters- poor at night and very poor at day,
40-30 (41-25) meters- fair at night and poor at day,
20-17 (22-15) meters- fair at night and fair at day,
15 (13) meters- poor at night and fair at day,
12(11) meters- very poor at night and poor to fair at day.
10 (11) meters- very poor at night and poor at day.
Keep in mind that almost daily during the northern hemisphere summer season you will find that the 10 (11) meter bands will open via short north-south and east-west propagation paths via sporadic E (Es). Also when multiple sporadic E (Es) clouds form and line up favorably much longer propagation paths open up on east-west paths. And last but not least north-south propagation paths occur across the equator via trans equatorial propagation (TEP).
SOUTHERN HEMISPHERE RADIO WAVE PROPAGATION-
80-60 (75-60) meters- good at night and poor at day,
40-30 (41-25) meters- good at night and fair at day,
20-17 (22-15) meters- very poor at night and good at day,
15 (13) meters- very poor at night and fair to good at day,
12 (11) meters- very poor at night and fair at day.
10 (11) meters- very poor at night and poor at day.
Received RF signal strength scale-
Very Good- +1 over S9 Or Greater
Good- S7-9
Fair- S4-6
Poor- S1-3
Very Poor- S0

We are now firmly in summer/winter solstice type of HF radio wave propagation conditions.
This means generally poor HF radio wave propagation conditions in the northern hemisphere especially at day and generally good HF radio wave propagation conditions in the southern hemisphere especially at day.
Globally HF radio wave propagation conditions are most evenly balanced
during the fall and spring equinoxes and most diametrically opposed during
the summer and winter solstice.
Conditions change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the
ecliptic, as well as by radio wave frequency. This is due to changes in the
maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2).
---------------------------------------------------------------------------------------------------------------------
This HF Radio wave propagation forecast is produced based on the NSA_CAP HF radio wave propagation prediction software. I wrote it beginning in the late 1980’s but I’m sorry to say that it can’t be distributed to the public.
And though this HF radio wave propagation forecast is produced based on the NSA_CAP, I do check the actual band conditions at my location in the state of Florida USA and tweak the forecast manually where and when necessary. And I also check global HF radio wave propagation conditions via remoted radio receivers around on every continent of the globe and tweak if and when necessary.
The hamateur radio JT65A mode RF signal levels received are based on 5 watts and ½ wave dipole up at 40 feet.
The hamateur radio PSK31 mode RF signal levels received are based on 25 watts and ½ wave dipole up at 40 feet.
The hamateur radio CW mode RF signal levels received are based on 50 watts and ½ wave dipole up at 40 feet.
The hamateur radio SSB RF mode signal levels received are based on 100 watts and ½ wave dipole up at 40 feet.
The HF shortwave broadcast band AM Mode RF signal levels are based on 100,000 watts (100 kw) and a typical VOA type curtain array antenna.
Please keep in mind that this is a relatively simplified HF radio wave
propagation forecast, so as to keep it easily understandable and applicable by the average radio enthusiast.
Globally HF radio wave propagation conditions are most evenly balanced
during the fall and spring equinoxes and most diametrically opposed during
the summer and winter solstices.
Conditions change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the
ecliptic, as well as by radio wave frequency. This is due to changes in the
maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2).
The D and E layers also come into play through RF radio wave signal
absorption and refraction. And then there is sporadic E (Es) radio wave
propagation that can really throw a wrench into the gears so to speak.
Things like sporadic E (Es) radio wave propagation and lightning storm
static can impact HF radio wave propagation in an unpredictable manner and
mostly bad.
Ongoing solar, space and geomagnetic weather goings on also impact HF radio
wave propagation conditions in a negative manner.
---------------------------------------------------------------------------------------------
Solar, Space & Geomagnetic Weather Conditions On
Sunday July 30, 2017-
Solar activity very low.
Earth's geomagnetic field was at a quiet level.
The three daily solar flux index (SFI) numbers were 69.4 69.5 69.5.
Considering that solar minimum won't occur for approximately 2 more years,
+/- 1 year, the daily < 70 solar flux numbers are occurring unusually early.
The official daily sunspot number (SSN) was 11.
But on Monday July 31, 2017 unofficially (determined by me) the daily sunspot number (SSN) was 0.
In 2017 officially there were 55 days with a daily sunspot number (SSN) of
0.
Considering that solar minimum won't occur for approximately 2 more years,
+/- 1 year, daily SSN's of 0 are occurring now unusually early.
In 2016 officially there were 32 days with a daily sunspot number (SSN) of
0. Considering that solar minimum won't occur for approximately three more
years, seeing daily SSN's of 0 occurring now is unusually early.
As we move forward towards the next solar minimum between solar cycle #24
and #25 the number of days with a 0 daily SSN will steadily increase.
Eventually every day for many, many, many months will see a 0, the big goose
egg.
In 2008 I forecasted solar cycle 24 to be the weakest in the past 100 years
and that forecast verified. I also forecasted that solar cycle 25 would be
virtually nonexistent, similar to the Dalton type solar minimum that
occurred in the early 1800's. Other than sunspot magnetic polarity it will probably be very difficult to determine when solar cycle 24 ended and solar cycle 25 began.
---------------------------------------------------------------------------------------------------------------------
There was 1 newly risen and/or emerged and/or existing earth facing official sun spot group (SSG).
Existing sunspot group (SSG) #12669 located near N18W36 with a simple alpha magnetic signature.
Continued active far side recurrent (which means that it has faced earth during the previous rotation of the sun and will again) sunspot group #2665 will rise above the east limb of the sun beginning on approximately Monday July 31, 2017. It could wreak havoc on earths geomagnetic field in the form of solar flares, coronal mass ejections (CME), solar fade outs, energetic proton storms and geomagnetic storming.
There was 2 unofficial and as of yet unnumbered earth facing sunspot groups (SSG) located near
N05W10,
N07E33.
There was no small in size C class or larger solar flare.
No earth facing coronal mass ejection (CME) related high latitude energetic proton storm occurred (polar cap absorption).
No solar flare related x-ray day side solar fade out (SFO) occurred.
--------------------------------------------------------------------------------------------------------------------
There was no earth facing coronal mass ejection (CME).
There was no earth facing collapsing magnetic filament eruption.
The 24 hour period 3 hour interval planetary K index (Kp) was at quiet geomagnetic conditions of
1 1 1 1 0 1 1 0.
The Kp geomagnetic indices are-
0-2- quiet
3- unsettled
4- active
5- minor geomagnetic storming
6- moderate
7- strong
8- severe
9- extreme
10- our atmosphere just got cooked off like on Mars and we are all dead.
The 24 hour period maximum and minimum planetary A index (Ap) ranged between
5 and 0,
which was at quiet geomagnetic conditions.
The Ap geomagnetic indices are-
0-7- quiet
8-15 unsettled
16-29- active
30-49- minor geomagnetic storm
50-99- major
100-400- severe
>401- our atmosphere just got cooked off like on Mars and we are all dead.
The 24 hour period averaged energetic proton flux was at a background level below 10 MeV.
The 24 hour period averaged background x-ray flux was at B9.21.
The 24 hour period averaged vertical component (Bz) of earth's geomagnetic magnetic field was at
-1.15 nT south.
The 24 hour period maximum and minimum disturbance storm time index (Dst) ranged between
-9 and +9 nT.
The 24 hour period maximum and minimum solar wind speed ranged between
381 and 289 km/s.
There was an earth facing southern hemisphere coronal hole (CH) #817.
It’s associated high speed solar wind stream (HSS) could wreak havoc on earth’s geomagnetic field in the form of minor geomagnetic storming conditions in approximately 1 more day.
There was a recently emerged earth facing northern hemisphere coronal hole (CH) #818.

GENERAL GUIDELINES CONCERNING CORRELATION OF PROPAGATION INDICES TO ACTUAL HF PROPAGATION CONDITIONS-
NOTE!!! The propagation indices "interpretations" are my personal
intellectual property. Therefore the radio wave propagation indices
interpretations contained herein is copyrighted © 1988-2017 by Thomas F.
Giella, W4HM, all rights reserved. Reproduction of information herein is
allowed without permission in advance as long as proper credit is given.
All 14 of the following indices have to occur as described below in order to
see the best global high frequency radio wave propagation possible,
something that happens rarely.
1.) Dropping geomagnetic field indices numbers are better, Kp of 0 best.
2.) A daily sunspot number of 150 or higher, 200 or higher best.
3.) A daily sunspot number of greater than 100 for routine stable formation
of the E Valley/F Layer ducting mechanism.
4.) Previous 24 hour Ap index under 10, fewer than 7 for several days
consecutively are best.
5.) Previous 3 hours Kp index fewer than 3 for mid latitude paths, fewer
than 2 for high latitude paths, 0 for several days consecutively is best.
6.) Energetic protons no greater than 10 MeV (10+0).
7.) Background x-ray flux levels greater than B1 for several days
consecutively, greater than C1 best.
8.) No current STRATWARM alert.
9.) Interplanetary magnetic field (IMF) Bz with a (positive number) sign,
indicates a lesser chance of high latitude path aurora
absorption/unpredictable refraction or scattering of medium frequency RF
signals, when the Kp is above 3.
10.) A -10 or better towards a positive number Dst index during the recovery
time after a geomagnetic storm, as related to the equatorial ring current. A
positive number is best.
11.) Rising positive T index number. The T Index tracks with the F2 layer
critical frequency (foF2) and sunspot number (SSN) and indicates the
capability of the F2 layer to refract RF signals.
12.) Galactic cosmic rays decrease to -3 units below zero and trending
towards zero.
13.) Energetic electron flux levels no greater than 2 MeV (2+0).
14. A solar wind speed of less than 300 km/s for several days consecutively.

Glenn Hauser logs July 30, 2017
** ARMENIA. 11845, July 30 at 1703, no signal from the R. Mi Amigo special as publicized to Europe at 17-19 today only; nor did I expect any, as they are certainly not aiming to be heard in North America (Glenn Hauser, OK, DX LISTENING DIGEST)
** COLOMBIA. 5910.355, July 30 at 0602, very poor music below noise level, no doubt Alcaraván Radio active again. At 0440, Wolfgang Büschel had measured it in Germany on 5910.351 (Glenn Hauser, OK, DX LISTENING DIGEST)
** NEW ZEALAND. 7425, July 30 at 1210 check, RNZI is still on NNE antenna with VG signal here. As Wolfgang Büschel points out, the latest change is 9630 ex-9700 at 05-07; presumably to avoid collision with Romania at 0600-0630. Unlogged here yet; now confronting the weak only slightly off-frequency R. Aparecida, Brasil. But EiBi shows CNR1 from site-q is also on 9630. Aoki says it`s via Geermu at 00-11 except for the Tuesday 06-09 siesta. China could be worse for NZ than RRI was (Glenn Hauser, OK, DX LISTENING DIGEST)
** PUERTO RICO. 5125 et al., July 30 at 0600 no carriers or tones on now from presumed Arecibo as earlier. These are supposed to run thru/until July 31. No reply yet from the HAARP guy in Alaska for confirmation of source, Chris Fallen, Ph.D., Assistant Research Professor in the Space Physics Group at the UAF Geophysical Institute (Glenn Hauser, OK, DX LISTENING DIGEST)
** SPAIN. 17855, July 30 at 1710 check, REE still AWOL from its North American frequency, the only European capable of a usable signal in our midday. A weakie on 17850 must be France at 162 degrees (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. 17362-USB, July 30 at 1711, synthetic YL with marine weather forecast consisting of nothing but wind direxion and speed in knots, seas in feet, day by day from now until Thursday, attributed to NWS Miami on July 30 for the tropical North Atlantic, between certain coördinates. EiBi shows this is WLO Mobile AL, which emits half-sesquihour broadcasts at 05, 11, 15, 17 and 23 UT. Why don`t they consolidate and make all numbers metric? Usually she says ``knots``, but sometimes ``k-t`` when the original text lacks the -s or the full word. Smart cookie (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. 7780, Sunday July 30 at 1215, VOA news about Pakistan back to odd timing other than hourtop amid WRMI Oldies service, S9 // 9395 at S7.
At 1708, the Oldies on 9455 are a JBA carrier, while 9395 rates a better but very poor level. The BS on 9955 is noticeably stronger but still insufficient (Glenn Hauser, OK, DX LISTENING DIGEST)

Global Daily HF Radio Wave Propagation Forecast-
HF radio wave propagation conditions are improving.
HAMATEUR & SW BROADCAST HF BANDS-
80-60 (75-60) meters- poor at night and very poor at day,
40-30 (41-25) meters- fair at night and poor at day,
20-17 (22-15) meters- fair at night and fair at day,
15 (13) meters- poor at night and fair at day,
12(11) meters- very poor at night and poor to fair at day.
10 (11) meters- very poor at night and poor at day.
Keep in mind that almost daily during the northern hemisphere summer season you will find that the 10 (11) meter bands will open via short north-south and east-west propagation paths via sporadic E (Es). Also when multiple sporadic E (Es) clouds form and line up favorably much longer propagation paths open up on east-west paths. And last but not least north-south propagation paths occur across the equator via trans equatorial propagation (TEP).
SOUTHERN HEMISPHERE RADIO WAVE PROPAGATION-
80-60 (75-60) meters- good at night and poor at day,
40-30 (41-25) meters- good at night and fair at day,
20-17 (22-15) meters- very poor at night and good at day,
15 (13) meters- very poor at night and fair to good at day,

We are now firmly in summer/winter solstice type of HF radio wave propagation conditions.
This means generally poor HF radio wave propagation conditions in the northern hemisphere especially at day and generally good HF radio wave propagation conditions in the southern hemisphere especially at day.
Globally HF radio wave propagation conditions are most evenly balanced
during the fall and spring equinoxes and most diametrically opposed during
the summer and winter solstice.
Conditions change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the
ecliptic, as well as by radio wave frequency. This is due to changes in the
maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2).
---------------------------------------------------------------------------------------------------------------------
This HF Radio wave propagation forecast is produced based on the NSA_CAP HF radio wave propagation prediction software. I wrote it beginning in the late 1980’s but I’m sorry to say that it can’t be distributed to the public.
And though this HF radio wave propagation forecast is produced based on the NSA_CAP, I do check the actual band conditions at my location in the state of Florida USA and tweak the forecast manually where and when necessary. And I also check global HF radio wave propagation conditions via remoted radio receivers around on every continent of the globe and tweak if and when necessary.
The hamateur radio JT65A mode RF signal levels received are based on 5 watts and ½ wave dipole up at 40 feet.
The hamateur radio PSK31 mode RF signal levels received are based on 25 watts and ½ wave dipole up at 40 feet.
The hamateur radio CW mode RF signal levels received are based on 50 watts and ½ wave dipole up at 40 feet.
The hamateur radio SSB RF mode signal levels received are based on 100 watts and ½ wave dipole up at 40 feet.
The HF shortwave broadcast band AM Mode RF signal levels are based on 100,000 watts (100 kw) and a typical VOA type curtain array antenna.
Please keep in mind that this is a relatively simplified HF radio wave
propagation forecast, so as to keep it easily understandable and applicable by the average radio enthusiast.
Globally HF radio wave propagation conditions are most evenly balanced
during the fall and spring equinoxes and most diametrically opposed during
the summer and winter solstices.
Conditions change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the
ecliptic, as well as by radio wave frequency. This is due to changes in the
maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2).
The D and E layers also come into play through RF radio wave signal
absorption and refraction. And then there is sporadic E (Es) radio wave
propagation that can really throw a wrench into the gears so to speak.
Things like sporadic E (Es) radio wave propagation and lightning storm
static can impact HF radio wave propagation in an unpredictable manner and
mostly bad.
Ongoing solar, space and geomagnetic weather goings on also impact HF radio
wave propagation conditions in a negative manner.
---------------------------------------------------------------------------------------------
Solar, Space & Geomagnetic Weather Conditions On
Saturday July 29, 2017-
Solar activity was low.
Earth's geomagnetic field was at a quiet level.
The three daily solar flux index (SFI) numbers were 70.4 69.9 69.7.
Considering that solar minimum won't occur for approximately 2 more years,
+/- 1 year, the daily < 70 solar flux numbers are occurring unusually early.
The official daily sunspot number (SSN) was 12.
In 2017 officially there were 55 days with a daily sunspot number (SSN) of
0.
Considering that solar minimum won't occur for approximately 2 more years,
+/- 1 year, daily SSN's of 0 are occurring now unusually early.
In 2016 officially there were 32 days with a daily sunspot number (SSN) of
0. Considering that solar minimum won't occur for approximately three more
years, seeing daily SSN's of 0 occurring now is unusually early.
As we move forward towards the next solar minimum between solar cycle #24
and #25 the number of days with a 0 daily SSN will steadily increase.
Eventually every day for many, many, many months will see a 0, the big goose
egg.
In 2008 I forecasted solar cycle 24 to be the weakest in the past 100 years
and that forecast verified. I also forecasted that solar cycle 25 would be
virtually nonexistent, similar to the Dalton type solar minimum that
occurred in the early 1800's. Other than sunspot magnetic polarity it will probably be very difficult to determine when solar cycle 24 ended and solar cycle 25 began.
---------------------------------------------------------------------------------------------------------------------
There was 1 newly risen and/or emerged and/or existing earth facing official sun spot group (SSG).
Newly emerged sunspot group (SSG) #12669 located near N18W23 with a slightly complex beta magnetic signature capable of releasing a small in size class C class solar flare and an isolated moderate in size M class solar flare.
(((((Continued active far side recurrent (which means that it has faced earth during the previous rotation of the sun and will again) sunspot group #2665 will rise above the east limb of the sun beginning on approximately Monday July 31, 2017. It could wreak havoc on earths geomagnetic field in the form of solar flares, coronal mass ejections (CME), solar fade outs, energetic proton storms and geomagnetic storming.)))))
There was 1 unofficial and as of yet unnumbered earth facing sunspot group (SSG) located near
N15W28.
There was no small in size C class or larger solar flare.
No earth facing coronal mass ejection (CME) related high latitude energetic proton storm occurred (polar cap absorption).
No solar flare related x-ray day side solar fade out (SFO) occurred.
--------------------------------------------------------------------------------------------------------------------
There was no earth facing coronal mass ejection (CME).
There was no earth facing collapsing magnetic filament eruption.
The 24 hour period 3 hour interval planetary K index (Kp) was at quiet geomagnetic conditions of
1 1 1 1 1 1 0 1.
The Kp geomagnetic indices are-
0-2- quiet
3- unsettled
4- active
5- minor geomagnetic storming
6- moderate
7- strong
8- severe
9- extreme
10- our atmosphere just got cooked off like on Mars and we are all dead.
The 24 hour period maximum and minimum planetary A index (Ap) ranged between
5 and 2,
which was at quiet geomagnetic conditions.
The Ap geomagnetic indices are-
0-7- quiet
8-15 unsettled
16-29- active
30-49- minor geomagnetic storm
50-99- major
100-400- severe
>401- our atmosphere just got cooked off like on Mars and we are all dead.
The 24 hour period averaged energetic proton flux was at a background level below 10 MeV.
The 24 hour period averaged background x-ray flux was at A5.92.
The 24 hour period averaged vertical component (Bz) of earth's geomagnetic magnetic field was at
-0.45 nT south.
The 24 hour period maximum and minimum disturbance storm time index (Dst) ranged between
-18 and 0 nT.
The 24 hour period maximum and minimum solar wind speed ranged between
417 and 350 km/s.
There was an earth facing southern hemisphere coronal hole (CH) #817.
It’s associated high speed solar wind stream (HSS) could wreak havoc on earth’s geomagnetic field in the form of minor geomagnetic storming conditions in approximately 1 more day.
There was a recently emerged earth facing northern hemisphere coronal hole (CH) #818.

GENERAL GUIDELINES CONCERNING CORRELATION OF PROPAGATION INDICES TO ACTUAL HF PROPAGATION CONDITIONS-
NOTE!!! The propagation indices "interpretations" are my personal
intellectual property. Therefore the radio wave propagation indices
interpretations contained herein is copyrighted © 1988-2017 by Thomas F.
Giella, W4HM, all rights reserved. Reproduction of information herein is
allowed without permission in advance as long as proper credit is given.
All 14 of the following indices have to occur as described below in order to
see the best global high frequency radio wave propagation possible,
something that happens rarely.
1.) Dropping geomagnetic field indices numbers are better, Kp of 0 best.
2.) A daily sunspot number of 150 or higher, 200 or higher best.
3.) A daily sunspot number of greater than 100 for routine stable formation
of the E Valley/F Layer ducting mechanism.
4.) Previous 24 hour Ap index under 10, fewer than 7 for several days
consecutively are best.
5.) Previous 3 hours Kp index fewer than 3 for mid latitude paths, fewer
than 2 for high latitude paths, 0 for several days consecutively is best.
6.) Energetic protons no greater than 10 MeV (10+0).
7.) Background x-ray flux levels greater than B1 for several days
consecutively, greater than C1 best.
8.) No current STRATWARM alert.
9.) Interplanetary magnetic field (IMF) Bz with a (positive number) sign,
indicates a lesser chance of high latitude path aurora
absorption/unpredictable refraction or scattering of medium frequency RF
signals, when the Kp is above 3.
10.) A -10 or better towards a positive number Dst index during the recovery
time after a geomagnetic storm, as related to the equatorial ring current. A
positive number is best.
11.) Rising positive T index number. The T Index tracks with the F2 layer
critical frequency (foF2) and sunspot number (SSN) and indicates the
capability of the F2 layer to refract RF signals.
12.) Galactic cosmic rays decrease to -3 units below zero and trending
towards zero.
13.) Energetic electron flux levels no greater than 2 MeV (2+0).
14. A solar wind speed of less than 300 km/s for several days consecutively.

We are now firmly in summer/winter solstice type of HF radio wave propagation conditions.
This means generally poor HF radio wave propagation conditions in the northern hemisphere especially at day and generally good HF radio wave propagation conditions in the southern hemisphere especially at day.
Globally HF radio wave propagation conditions are most evenly balanced
during the fall and spring equinoxes and most diametrically opposed during
the summer and winter solstice.
Conditions change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the
ecliptic, as well as by radio wave frequency. This is due to changes in the
maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2).
---------------------------------------------------------------------------------------------------------------------
This HF Radio wave propagation forecast is produced based on the NSA_CAP HF radio wave propagation prediction software. I wrote it beginning in the late 1980’s but I’m sorry to say that it can’t be distributed to the public.
And though this HF radio wave propagation forecast is produced based on the NSA_CAP, I do check the actual band conditions at my location in the state of Florida USA and tweak the forecast manually where and when necessary. And I also check global HF radio wave propagation conditions via remoted radio receivers around on every continent of the globe and tweak if and when necessary.
The hamateur radio JT65A mode RF signal levels received are based on 5 watts and ½ wave dipole up at 40 feet.
The hamateur radio PSK31 mode RF signal levels received are based on 25 watts and ½ wave dipole up at 40 feet.
The hamateur radio CW mode RF signal levels received are based on 50 watts and ½ wave dipole up at 40 feet.
The hamateur radio SSB RF mode signal levels received are based on 100 watts and ½ wave dipole up at 40 feet.
The HF shortwave broadcast band AM Mode RF signal levels are based on 100,000 watts (100 kw) and a typical VOA type curtain array antenna.
Please keep in mind that this is a relatively simplified HF radio wave
propagation forecast, so as to keep it easily understandable and applicable by the average radio enthusiast.
Globally HF radio wave propagation conditions are most evenly balanced

Conditions change daily, weekly, monthly, yearly and by decade, as the

maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2).
The D and E layers also come into play through RF radio wave signal
absorption and refraction. And then there is sporadic E (Es) radio wave
propagation that can really throw a wrench into the gears so to speak.
Things like sporadic E (Es) radio wave propagation and lightning storm
static can impact HF radio wave propagation in an unpredictable manner and
mostly bad.
Ongoing solar, space and geomagnetic weather goings on also impact HF radio
wave propagation conditions in a negative manner.

Solar, Space & Geomagnetic Weather Conditions On
Saturday July 29, 2017-
Solar activity was low.
Earth's geomagnetic field was at a quiet level.
The three daily solar flux index (SFI) numbers were 70.4 69.9 69.7.
Considering that solar minimum won't occur for approximately 2 more years,
+/- 1 year, the daily < 70 solar flux numbers are occurring unusually early.
The official daily sunspot number (SSN) was 12.
In 2017 officially there were 55 days with a daily sunspot number (SSN) of
0.
Considering that solar minimum won't occur for approximately 2 more years,
+/- 1 year, daily SSN's of 0 are occurring now unusually early.
In 2016 officially there were 32 days with a daily sunspot number (SSN) of
0. Considering that solar minimum won't occur for approximately three more
years, seeing daily SSN's of 0 occurring now is unusually early.
As we move forward towards the next solar minimum between solar cycle #24
and #25 the number of days with a 0 daily SSN will steadily increase.
Eventually every day for many, many, many months will see a 0, the big goose
egg.
In 2008 I forecasted solar cycle 24 to be the weakest in the past 100 years
and that forecast verified. I also forecasted that solar cycle 25 would be
virtually nonexistent, similar to the Dalton type solar minimum that
occurred in the early 1800's. Other than sunspot magnetic polarity it will probably be very difficult to determine when solar cycle 24 ended and solar cycle 25 began.
---------------------------------------------------------------------------------------------------------------------
There was 1 newly risen and/or emerged and/or existing earth facing official sun spot group (SSG).
Newly emerged sunspot group (SSG) #12669 located near N18W23 with a slightly complex beta magnetic signature capable of releasing a small in size class C class solar flare and an isolated moderate in size M class solar flare.
(((((Continued active far side recurrent (which means that it has faced earth during the previous rotation of the sun and will again) sunspot group #2665 will rise above the east limb of the sun beginning on approximately Monday July 31, 2017. It could wreak havoc on earths geomagnetic field in the form of solar flares, coronal mass ejections (CME), solar fade outs, energetic proton storms and geomagnetic storming.)))))
There was 1 unofficial and as of yet unnumbered earth facing sunspot group (SSG) located near
N15W28.
There was no small in size C class or larger solar flare.
No earth facing coronal mass ejection (CME) related high latitude energetic proton storm occurred (polar cap absorption).
No solar flare related x-ray day side solar fade out (SFO) occurred.
--------------------------------------------------------------------------------------------------------------------
There was no earth facing coronal mass ejection (CME).
There was no earth facing collapsing magnetic filament eruption.
The 24 hour period 3 hour interval planetary K index (Kp) was at quiet geomagnetic conditions of
1 1 1 1 1 1 0 1.
The Kp geomagnetic indices are-
0-2- quiet
3- unsettled
4- active
5- minor geomagnetic storming
6- moderate
7- strong
8- severe
9- extreme
10- our atmosphere just got cooked off like on Mars and we are all dead.
The 24 hour period maximum and minimum planetary A index (Ap) ranged between
5 and 2,
which was at quiet geomagnetic conditions.
The Ap geomagnetic indices are-
0-7- quiet
8-15 unsettled
16-29- active
30-49- minor geomagnetic storm
50-99- major
100-400- severe
>401- our atmosphere just got cooked off like on Mars and we are all dead.
The 24 hour period averaged energetic proton flux was at a background level below 10 MeV.
The 24 hour period averaged background x-ray flux was at A5.92.
The 24 hour period averaged vertical component (Bz) of earth's geomagnetic magnetic field was at
-0.45 nT south.
The 24 hour period maximum and minimum disturbance storm time index (Dst) ranged between
-18 and 0 nT.
The 24 hour period maximum and minimum solar wind speed ranged between
417 and 350 km/s.
There was an earth facing southern hemisphere coronal hole (CH) #817.
It’s associated high speed solar wind stream (HSS) could wreak havoc on earth’s geomagnetic field in the form of minor geomagnetic storming conditions in approximately 1 more day.
There was a recently emerged earth facing northern hemisphere coronal hole (CH) #818.

interpretations contained herein is copyrighted © 1988-2017 by Thomas F.
Giella, W4HM, all rights reserved. Reproduction of information herein is

All 14 of the following indices have to occur as described below in order to
see the best global high frequency radio wave propagation possible,
something that happens rarely.
1.) Dropping geomagnetic field indices numbers are better, Kp of 0 best.
2.) A daily sunspot number of 150 or higher, 200 or higher best.
3.) A daily sunspot number of greater than 100 for routine stable formation
of the E Valley/F Layer ducting mechanism.
4.) Previous 24 hour Ap index under 10, fewer than 7 for several days
consecutively are best.
5.) Previous 3 hours Kp index fewer than 3 for mid latitude paths, fewer
than 2 for high latitude paths, 0 for several days consecutively is best.
6.) Energetic protons no greater than 10 MeV (10+0).
7.) Background x-ray flux levels greater than B1 for several days
consecutively, greater than C1 best.
8.) No current STRATWARM alert.
9.) Interplanetary magnetic field (IMF) Bz with a (positive number) sign,
indicates a lesser chance of high latitude path aurora
absorption/unpredictable refraction or scattering of medium frequency RF
signals, when the Kp is above 3.
10.) A -10 or better towards a positive number Dst index during the recovery
time after a geomagnetic storm, as related to the equatorial ring current. A
positive number is best.
11.) Rising positive T index number. The T Index tracks with the F2 layer
critical frequency (foF2) and sunspot number (SSN) and indicates the
capability of the F2 layer to refract RF signals.
12.) Galactic cosmic rays decrease to -3 units below zero and trending
towards zero.
13.) Energetic electron flux levels no greater than 2 MeV (2+0).
14. A solar wind speed of less than 300 km/s for several days consecutively.

Glenn Hauser logs July 29-30, 2017
** ALBANIA [non]. 5850, July 29 at 2258, WRMI is on with IS & ID runup to hourtop, 2300 R. Tirana IS and sign-on not mentioning any SW frequency, just ``from now on`` at the web address. Suspect this SW arrangement I proposed is somewhat extra-official, with shortwaveservice in Germany as intermediary (Glenn Hauser, OK, DX LISTENING DIGEST)
** EQUATORIAL GUINEA. 6250, July 30 at 0005 check, no signal from RNRGE, Malabo, so apparently done with the all-night testing. We should still be able to hear them from sign-on which used to be 0530, but will they stay on later than the old sign-off of 1830? (Glenn Hauser, OK, DX LISTENING DIGEST)
** NORTH AMERICA. 6950-USB, July 30 at 0111, rockmusic at S8-S9, no doubt Wolverine Radio, as confirmed by ID at 0115. Tonight`s key word is ``help`` per numerous logs from 0033 to 0146 at
https://www.hfunderground.com/board/index.php/topic,36415.0.html
I didn`t listen long with all the other stuff going on (Glenn Hauser, OK, DX LISTENING DIGEST)
** PUERTO RICO. 5125.00, July 30 at 0006, extremely strong S9+15 to S9+30 open carrier, something new. I`m checking since this news emerged via roger on the DXLD yg:
http://bit.ly/2eNEhME
about ionospheric heating experiments from the Arecibo, Puerto Rico, radio telescope, on behalf of the same guy who brought us HAARP last winter from Gakona, Alaska.
``Arecibo ionosphere HF radio modification campaign!
[Excerpts:] 23 July: If you are reading this, then another radio event of possible interest is the upcoming Arecibo ionosphere HF heating campaign during 24 to 31 July 2017. The new Arecibo ionosphere HF heater nominally transmits 600 kilowatts net power (100 to 200 megawatts effective radiated power) and has a unique Cassegrain dual-array antenna design that increases gain of three crossed dipoles for each band using the signature 1000 ft spherical dish reflector.
During the upcoming campaign, the Arecibo HF transmitter is limited to two frequencies, 5.125 and 8.175 MHz. Campaign HF transmissions will start at approximately 1600 hours UTC and be active approximately 24 hours per day, with some occasional downtime for maintenance and other activities lasting one or more hours. Generally, the 8.175 MHz transmissions will occur in the daytime when foF2 is expected to exceed that value, between approximately 1830 and 2230 hours UTC. Otherwise the HF transmissions will occur at 5.125 MHz. These transmissions will be in the vertical direction so this is an excellent opportunity to observe NVIS from a powerful transmitter in Puerto Rico.
24 July: Did you copy Arecibo during the 24-31 July 2017 HF campaign? Get your QSL card! This morning I received the following information by email from Ángel Vásquez, Head of Telescope Operations and Spectrum Manager at Arecibo:
I’m Ángel WP3R, president and trustee of KP4AO, the Arecibo Amateur Radio Club. KP4AO has QSL cards that have been made because of our Special Event Runs and the MoonBounce we did. My personal QSL manager, W3HNK does the QSL’ing also for KP4AO. I can give him a call and have him send SWL QSL’s to the interested parties. All that is needed is a SASE to W3HNK. His Address can be found on QRZ.com or WM7D.net.
25 July 2017: I originally reported the Arecibo high-power HF operations to be transmitted at either 5.125 or 8.175 MHz, depending on local foF2. Note that these are just estimates and the actual transmitted frequency may be adjusted slightly from those values for various reasons. Arecibo is currently transmitting 5095 kHz at 0000 hours 25 July 2017 (UTC).``
So here`s what I hear: first at 0007, I compare the 5125 signal to nearby 5 MHz transmitters:
5129.8, WBCQ, JBA carrier --- will get blown away by this thing
5085, WTWW not on yet [see separate log later]
5050, WWRB, S9+15
5040, RHC Creole, S9 to S9+25
5025, Rebelde, S7-S9, undermodulated
[see also USA: 6993]
Assuming 5125 will continue to be unmodulated, I tune around elsewhere, but at 0031 I notice that different ascending tones are now being transmitted in steps. This is not unlike some proof-of-performance runs by AM broadcast stations, but why would they be doing this? The huge ERP carrier alone is all that`s needed to heat the ionosphere. And if they can transmit these tones, they could also easily include some kind of ID! So I am not positive all this is really Arecibo. If not, quite a spoiler!
The tone sequences start over from low to high about every two minutes, at 0034, 0036, 0038. The higher-pitched ones being pure tones, produce what amount to distinct carriers on corresponding frequencies apart from 5125.00, in fact landing far beyond poor WBCQ circa 5130.
At 0040 I start to follow the sequence with the NRD-545 on 0.1 kHz step tuning. Each lasts just a few seconds. I suppose the same thing is happening on the lower side but not listening there. 5133.2, 5133.6, 5134.0, 5134.4, 5134.8 --- so these are 400 Hz apart.
Next run at 0043 I catch starting at 5126.1, then 5126.5, 5126.7, 5126.9, 5127.1, 5127.3, 5127.5, 5127.7, 5127.9, 5128.1, 5128.3, 5128.5, 5128.7, 5128.9 (and now traces of WBCQ at different pitches underneath), 5129.1, 5129.3, 5129.5, 5129.7, 5129.9 where it stops, so these were 200 Hz apart; and back down to start up again:
5125.9, 5126.1, 5126.3, 5126.5, 5126.7, also at 200 Hz --- and I tune up above to find some much higher ones going at same time far beyond the WBCQ frequency:
5135.9, 5137.4, 5138.3, 5132.2, 5143.1, 5143.8, 5144.6 where it stops. I may have missed some digits trying to keep up with them, as these were mostly, but not all, 900 Hz apart. More of same I do not track.
At 0100* carrier goes off, back on circa *0102 with dead air; 0104 more tone test but this time steady at high pitch. 0108 dead air; 0110 high tones.
At 0114 yet another variation: the carrier cuts off and on between tones, something it was not doing earlier. There was never anything on 5095 or other frequencies between. And so it went.
0330 recheck, nothing on 5125 or 5095, but a big S9+20 OC on 5100, where we have heard such before. Could that be Arecibo all along? (Glenn Hauser, OK, DX LISTENING DIGEST)
** U K [non]. 7445, July 30 at 0054, nice ME song at S8, adding to all the music stations on 6, 7 and 9 MHz this evening. 0056 talk sounds Farsi but must be Dari, mottoes(?) with music interludes, and one ID-like in passing, sounds like ``Sedoye Samá``, 0059 mentions Afghanistan and off at 0059.5*. HFCC shows BBCWS via Woofferton, but the Afghan service alternating Pashto & Dari is to continue from Oman on 7445 until 0330 (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A [and non]. WORLD OF RADIO 1888 monitoring: confirmed Saturday July 29 at 2254, the 2230 airing on WBCQ 9330.25v-CUSB, poor. Also confirmed Sat July 29 at 2300 on WRMI 11580, good, after at least 5 minutes of music fill. Also confirmed UT Sunday July 30 at 0200 on WRMI, 11580, good. Also confirmed from 0345 UT Sunday July 30 on WA0RCR, 1860-AM, MO, later than usual. (Schedule here http://wa0rcr.com/sched.html does not include WOR at non-exact times)

(Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. 5097.9, July 30 at 0059, parasitic weak spur from WTWW-2 which has just signed on 5085 with music, 0101 Ted offers QSLs for e-mail; ham ads; 0106 `Theater Organ in the Ozarx` finally starts. If Arecibo had been on 5095 tonight, there could be a problem, but not on 5125 (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. 6993, July 30 at 0110, very poor carrier, which is often detectable, and as previously logged, in DXLD 16-16 and 16-46, it`s WH2XWF, an experimental 164-watt transmitter with several locations in Florida, to study ionospheric disturbances; re-logged in honor of Arecibo 5125, which ought to have some such callsign (Glenn Hauser, OK, DX LISTENING DIGEST)

Glenn Hauser logs July 28-29, 2017
** ANGUILLA. 6090, July 29 at 0607 check, CB is on tonight with PMS; 11775 day frequency is off at 1331 check, but on by 1923 fair at S9-S7. I had just heard the expletive ``by cracky`` from DGS on // 13845 WWCR (Glenn Hauser, OK, DX LISTENING DIGEST)
** CHINA. 11935, July 28 at 1237, pop music and talk in Russian with strange accent about football; 1241 mentions ``kitaysky``, 1243 to Firedragon-like music. Must be MPK == CRI in Russian as scheduled 10-13, 500 kW, 37 degrees from SZG site i.e. toward DBP and onward to Severnaya Amerika (per HFCC, at 1200-1227 there would have been a collision with RVA westward from Palauig in Hmong). (Glenn Hauser, OK, DX LISTENING DIGEST)
** CUBA. 15140, July 29 at 1930, RHC English is S9+10 of extreme distortion: I have to listen a while to decide it`s really English; first seemed Italian, but guess it was the Spanish accent. When will RHC ever put its weblang Italian on SW? Carrier is OK, so it`s entirely a modulation problem, perhaps originating in the studio or link. At least someone eventually noticed, since transmitter is off at 1952 check; while 15370 in Spanish song remains strong. Something is always wrong at RHC. Patria o suerte, ¡pensaremos! (Glenn Hauser, OK, DX LISTENING DIGEST)
** EQUATORIAL GUINEA. 6250, July 29 at 0605, RNRGE, Malabo poor with M&W in Spanish. Wolfgang Bueschel and Patrick Robich think the reactivation is thanks to an Afrika-tour by Chinese techs from BEFF transmitter factory (Glenn Hauser, OK, DX LISTENING DIGEST)
** OKLAHOMA. Re my log of KAKO 91.3 ``Ada`` -- Looking again at FCC coverage map, the transmitter site is axually near Shawnee, not Ada, and Shawnee is much closer to OKC, in fact about halfway there. Community of license, Ada, is barely within the same contour! Ada 2010y population was only 16.8 kilopersons, so who cares? KAKO again inaudible here under dead conditions (Glenn Hauser, Enid, DX LISTENING DIGEST)
** U S A. WORLD OF RADIO 1888 monitoring: confirmed Friday July 28 at 2330 on WBCQ 9330.25v-CUSB, fair. Also confirmed via UTwente SDR, Saturday July 29 from 1431 on Hamburger Lokalradio, 7265-CUSB. This week it`s good and steady, no QRM, but not enough to suppress noise level, 100% copy except for skipping in the webcast. Right up to 1500* when as usual at end of WOR, just stops, no sign-off or HLR ID; and nothing further to be heard either from China. Other weeks, HLR/WOR not audible at all: is solely due to propagational variations? Next:
Sat 2230 WBCQ 9330v-CUSB to WSW
Sat 2300 WRMI 11580 to NE
Sun 0200 WRMI 11580 to NE
Sun 0315v WA0RCR 1860-AM ND
Sun 1030 HLR 9485-CUSB to WSW
Sun 2330 WBCQ 9330v-CUSB to WSW
Mon 0300v WBCQ 5130v Area 51 to WSW
Mon 0330 WRMI 9955 to SSE
Mon 2330 WBCQ 9330v-CUSB to WSW
Tue 0030 WRMI 7730 to WNW
(Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. 7780, Saturday July 29 at 1333, WRMI is on and // 9395, 9455 so on weekends `Oldies` gets not one, not two, but three frequencies, none outstanding. 7780 had been expanded weekdays to carry `The Power Hour` after 1200. Still something there on 7780 at 1412.
`Oldies` program really needs to be on higher frequency in daytime. July 29 at 1930 check, 9395 & 9455 are detectable but far too weak to enjoy the music. Why not 13695, a former WRMI daytime frequency on the NW antenna? Perhaps the 9ers are good enough at half the distance from Okeechobee to Oklahoma, but hardly diverse in frequency. Likewise, needs to be on a lower frequency overnight to escape plunging MUFs, to 7 or even 5 MHz band (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. 9930, Sat July 29 at 1924, WTWW-2 is off, so probably missed TOITO an hour earlier. 9475, WTWW-1 is on with suptorted QSO show, so 9930 with another ham show is hardly necessary (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. 17775, Friday July 28 at 2010, KVOH is still on with sermon in English, but big wobble on carrier, worse than usual, such that even in AM mode it`s making a hum and distortion on S7-S9+20 signal (Glenn Hauser, OK, DX LISTENING DIGEST)

Global Daily HF Radio Wave Propagation Forecast-
HF radio wave propagation conditions are in a deteriorated state.
HAMATEUR & SW BROADCAST HF BANDS-
NORTHERN HEMISPHERE RADIO WAVE PROPAGATION-
80-60 (75-60) meters- poor at night and very poor at day, 40-30 (41-25) meters- fair at night and poor at day, 20-17 (22-16) meters- fair at night and fair at day, 15 (13) meters- poor at night and fair at day, 12-10 (11) meters- very poor at night and very poor at day.
Keep in mind that almost daily during the northern hemisphere summer season you will find that the 10 (11) meter bands will open via short north-south and east-west propagation paths via sporadic E (Es). Also when multiple sporadic E (Es) clouds form and line up favorably much longer propagation paths open up on east-west paths. And last but not least north-south propagation paths occur across the equator via trans equatorial propagation (TEP).
SOUTHERN HEMISPHERE RADIO WAVE PROPAGATION-
80-60 (75-60) meters- fair at night and poor at day,
40-30 (41-25) meters- fair at night and fair at day,
20-17 (22-16) meters- very poor at night and fair at day,
15 (13) meters- very poor at night and poor at day,
12-10 (11) meters- very poor at night and very poor at day.
Received RF signal strength scale-
Very Good- +1 over S9 Or Greater

We are now firmly in summer/winter solstice type of HF radio wave propagation conditions.
This means generally poor HF radio wave propagation conditions in the northern hemisphere especially at day and generally good HF radio wave propagation conditions in the southern hemisphere especially at day.
Globally HF radio wave propagation conditions are most evenly balanced
during the fall and spring equinoxes and most diametrically opposed during
the summer and winter solstice.
Conditions change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the
ecliptic, as well as by radio wave frequency. This is due to changes in the
maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2).

This HF Radio wave propagation forecast is produced based on the NSA_CAP HF radio wave propagation prediction software. I wrote it beginning in the late 1980’s but I’m sorry to say that it can’t be distributed to the public.
And though this HF radio wave propagation forecast is produced based on the NSA_CAP, I do check the actual band conditions at my location in the state of Florida USA and tweak the forecast manually where and when necessary. And I also check global HF radio wave propagation conditions via remoted radio receivers around on every continent of the globe and tweak if and when necessary.
The hamateur radio JT65A mode RF signal levels received are based on 5 watts and ½ wave dipole up at 40 feet.
The hamateur radio PSK31 mode RF signal levels received are based on 25 watts and ½ wave dipole up at 40 feet.
The hamateur radio CW mode RF signal levels received are based on 50 watts and ½ wave dipole up at 40 feet.
The hamateur radio SSB RF mode signal levels received are based on 100 watts and ½ wave dipole up at 40 feet.
The HF shortwave broadcast band AM Mode RF signal levels are based on 100,000 watts (100 kw) and a typical VOA type curtain array antenna.
Please keep in mind that this is a relatively simplified HF radio wave
propagation forecast, so as to keep it easily understandable and applicable by the average radio enthusiast.
Globally HF radio wave propagation conditions are most evenly balanced
during the fall and spring equinoxes and most diametrically opposed during
the summer and winter solstices.
Conditions change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the
ecliptic, as well as by radio wave frequency. This is due to changes in the
maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2).
The D and E layers also come into play through RF radio wave signal
absorption and refraction. And then there is sporadic E (Es) radio wave
propagation that can really throw a wrench into the gears so to speak.
Things like sporadic E (Es) radio wave propagation and lightning storm
static can impact HF radio wave propagation in an unpredictable manner and
mostly bad.
Ongoing solar, space and geomagnetic weather goings on also impact HF radio
wave propagation conditions in a negative manner.
---------------------------------------------------------------------------------------------
Solar, Space & Geomagnetic Weather Conditions On
Friday July 28, 2017-
Solar activity was very low.
Earth's geomagnetic field was at an unsettled level.
The three daily solar flux index (SFI) numbers were 69.9 69.5 70.1.
Considering that solar minimum won't occur for approximately 2 more years,
+/- 1 year, the daily < 70 solar flux numbers are occurring unusually early.
The official daily sunspot number (SSN) was 0.
That was day 3 in a row with no visible sunspots.
In 2017 officially there were 55 days with a daily sunspot number (SSN) of
0.
Considering that solar minimum won't occur for approximately 2 more years,
+/- 1 year, daily SSN's of 0 are occurring now unusually early.
In 2016 officially there were 32 days with a daily sunspot number (SSN) of
0. Considering that solar minimum won't occur for approximately three more
years, seeing daily SSN's of 0 occurring now is unusually early.
As we move forward towards the next solar minimum between solar cycle #24
and #25 the number of days with a 0 daily SSN will steadily increase.
Eventually every day for many, many, many months will see a 0, the big goose
egg.
In 2008 I forecasted solar cycle 24 to be the weakest in the past 100 years
and that forecast verified. I also forecasted that solar cycle 25 would be
virtually nonexistent, similar to the Dalton type solar minimum that
occurred in the early 1800's. Other than sunspot magnetic polarity it will probably be very difficult to determine when solar cycle 24 ended and solar cycle 25 began.
---------------------------------------------------------------------------------------------------------------------
There was 0 newly risen and/or emerged and/or existing earth facing official sun spot group (SSG).
(((((However continued active recurrent (which means that it has faced earth during the previous rotation of the sun and will again) sunspot group #2665 will rise above the east limb of the sun beginning on Monday July 31, 2017. It could wreak havoc on earths geomagnetic field in the form of solar flares, coronal mass ejections (CME), solar fade outs, energetic proton storms and geomagnetic storming.)))))
There was 0 unofficial and as of yet unnumbered earth facing sunspot group (SSG).
There was no small in size C class or larger solar flare.
No earth facing coronal mass ejection (CME) related high latitude energetic proton storm occurred (polar cap absorption).
No solar flare related x-ray day side solar fade out (SFO) occurred.
--------------------------------------------------------------------------------------------------------------------
There was no earth facing coronal mass ejection (CME).
There was no earth facing collapsing magnetic filament eruption.
The 24 hour period 3 hour interval planetary K index (Kp) was at unsettled to quiet geomagnetic conditions of
2 1 1 2 2 3 3 2.
The Kp geomagnetic indices are-
0-2- quiet
3- unsettled
4- active
5- minor geomagnetic storming
6- moderate
7- strong
8- severe
9- extreme
10- our atmosphere just got cooked off like on Mars and we are all dead.
The 24 hour period maximum and minimum planetary A index (Ap) ranged between
8 and 3,
which was at unsettled to quiet geomagnetic conditions.
The Ap geomagnetic indices are-
0-7- quiet
8-15 unsettled
16-29- active
30-49- minor geomagnetic storm
50-99- major
100-400- severe
>401- our atmosphere just got cooked off like on Mars and we are all dead.
The 24 hour period averaged energetic proton flux was at a background level below 10 MeV.
The 24 hour period averaged background x-ray flux was at B1.56.
The 24 hour period averaged vertical component (Bz) of earth's geomagnetic magnetic field was at
-0.50 nT south.
The 24 hour period maximum and minimum disturbance storm time index (Dst) ranged between
-15 and -4 nT.
The 24 hour period maximum and minimum solar wind speed ranged between
470 and 420 km/s.
There was an earth facing southern hemisphere coronal hole (CH) #817.
(((((It’s associated high speed solar wind stream (HSS) could wreak havoc on earth’s geomagnetic field in the form of geomagnetic storming conditions in a couple of more days.)))))

All 14 of the following indices have to occur as described below in order to
see the best global high frequency radio wave propagation possible,
something that happens rarely.
1.) Dropping geomagnetic field indices numbers are better, Kp of 0 best.
2.) A daily sunspot number of 150 or higher, 200 or higher best.
3.) A daily sunspot number of greater than 100 for routine stable formation
of the E Valley/F Layer ducting mechanism.
4.) Previous 24 hour Ap index under 10, fewer than 7 for several days
consecutively are best.
5.) Previous 3 hours Kp index fewer than 3 for mid latitude paths, fewer
than 2 for high latitude paths, 0 for several days consecutively is best.
6.) Energetic protons no greater than 10 MeV (10+0).
7.) Background x-ray flux levels greater than B1 for several days
consecutively, greater than C1 best.
8.) No current STRATWARM alert.
9.) Interplanetary magnetic field (IMF) Bz with a (positive number) sign,
indicates a lesser chance of high latitude path aurora
absorption/unpredictable refraction or scattering of medium frequency RF
signals, when the Kp is above 3.
10.) A -10 or better towards a positive number Dst index during the recovery
time after a geomagnetic storm, as related to the equatorial ring current. A
positive number is best.
11.) Rising positive T index number. The T Index tracks with the F2 layer
critical frequency (foF2) and sunspot number (SSN) and indicates the
capability of the F2 layer to refract RF signals.
12.) Galactic cosmic rays decrease to -3 units below zero and trending
towards zero.
13.) Energetic electron flux levels no greater than 2 MeV (2+0).
14. A solar wind speed of less than 300 km/s for several days consecutively.
