Global Daily HF Radio Wave Propagation Forecast-
HF radio wave propagation conditions- improving.
Northern Hemisphere Radio Wave Propagation Forecast-
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 to fair at day.

12- 24.89-24.99
11- 25.6-26.1
10- 28.0-29.7
During the northern hemisphere winter season the higher HF bands of 10-20 meters (11-19 meters) close sooner due to less sun light illuminating the ionosphere than in the southern hemisphere. But the maximum usable frequency (MUF) is higher than in the southern hemisphere as the F layer of the ionosphere is lower in height and more dense.
Southern Hemisphere Radio Wave Propagation Forecast-
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,

10- 28.0-29.7
Keep in mind that almost daily during the southern 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).
---------------------------------------------------------------------------------------------------------------------
This HF Radio wave propagation forecast is produced based on the SIGINT_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 general public.
And though this HF radio wave propagation forecast is produced based on the SIGINT_CAP, I do check the actual band conditions at my location in the USA and tweak the forecast manually where and when necessary. I also check global HF radio wave propagation conditions via remoted radio receivers around on every continent of the globe and tweak the forecast manually 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 high gain 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.

Glenn Hauser logs September 28-29, 2017
** BOLIVIA. 5935.01+, Sept 28 at 2350, again a JBA carrier fighting high local noise level radiated out of a lamp which needs to be turned off, from presumed R. Yura before WWCR creams it (Glenn Hauser, OK, DX LISTENING DIGEST)
** CUBA. 5040, Sept 29 at 0602, RHC English is still on here starting another hour repeat. Nominal close on this frequency is 0600; probably will chop it off abruptly when they get around to it (Glenn Hauser, OK, DX LISTENING DIGEST)
** CUBA. 17730, Sept 29 at 1311 no signal from RHC nor at 1354, but 17580 is very poorly audible. I had first found algo on 15730 and thought it might be a mistake for 17730, but going back to 15730 it`s off shortly later before I can check for //. Meanwhile 15370 is inbooming. Finally at 1420, 17730 is on, with poor S8 music and 17580 is now off, while 15370 continues at S9+40.
RHC website is still displaying the B-14 schedule!!
http://www.radiohc.cu/interesantes/estaticas/frecuencias
Something`s always wrong at RHC.
NDXC/Aoki currently for A-17 shows:
15370 at 1300-1500
15730 at 2230-0030
17580 at 1100-1400
17730 at 1100-1500
(Glenn Hauser, OK, DX LISTENING DIGEST)
** INDONESIA. 3325, Sept 29 at 1205 news in Indonesian from RRI Palangkaraya, apparently alone, altho 10 minutes earlier Bougainville seemed still on too. 1233, YL with love song in English, 1235 YL & OM dialog in Indonesian (Glenn Hauser, OK, DX LISTENING DIGEST)
** INDONESIA. 9525.940, Sept 29 at 1357, very poor S4-S6 music, but obviously VOI is back after a break, and once again bumped up frequency almost one kHz; different transmitters? I had been checking the 9525 area almost every morning, and nothing heard since September 13. Atsunori Ishida also reports ``9526`` first today from 1155 during Chinese, but ``9525`` low modulation carrier had been on earlier at *0936-0949*. So they gave up on that one, fired up the other one. Later I see that Wolfgang Büschel agrees on this precise frequency. After 1400, no QRM from 9525.0; this season we no longer have to cope with CRI, but HFCC shows KBS at 14-16, wooden? (Glenn Hauser, OK, DX LISTENING DIGEST)
** KOREA NORTH [non]. 6040, Sept 29 at 1300, very poor signal S7-S9 with Shiokaze music, ex-5965 where it had been for several weeks. Ron Howard reported the change occurred yesterday Sept 28 when the broadcast was in English (Glenn Hauser, OK, DX LISTENING DIGEST)
** NEW ZEALAND. 6170, Sept 29 at 1241, surprised to find RNZI already on here, instead of from 1259; concluding a BBCWS item about ``maggot masters`` on `The Food Chain`, to be back next week at 1:15 am Saturday. Nothing on 7425, and this is good S9+20, still not likely on NNW antenna only, which used to be the case at 11-13 UT only, whatever the frequency. Then some music. 1248 YL DJ stumbles over time check as ``eleven and a half minutes to two on 101 FM``, more songs, ``I Need Your Love``. WRTH 2017 page 300 shows RNZ National multiple FM transmitters all over the country are only in the 101s; what a branding idea!
So DST of UT+13 has started in NZ (never mind the dateline), first thing Saturday morning rather than Sunday at 2 am local as in North America? NO, timedanddate.com shows it already started last Sunday September 24 when 2 am became 3 am. This has obviously caused confusion in the SW scheduling, perhaps to be fixed in a day or few, as the 1258 QSY should stay at same UT regardless of local clox. Has 6170 been running before 1300 already since Sept 24? But most of the programming, from National will have to be one UT hour earlier.
1257 fade down another timecheck in peculiar backward and semi-minute format, ``two and half to two`` to QSY announcement from ``this frequency`` (whatever) to 6170, but we are already there! Canned announcer is totally out of touch with reality. There is no break or change in strength, but we are treated to almost two minutes of uninterrupted Bell Bird IS (does it have a name, like RA`s defunct kookaburra, Jacko?? BTW, parts of Australia don`t go on DST until one week later, October 1).
1300 into news from RNZ National, leading with evacuation of thousands from Ambae Island in Vanuatu where there is ash and acid rain falling, expecting an all-out eruption. 1307 news ends as from ``RNZ International``, not RNZ Pacific which is supposedly the politically correct name now, and into `Dateline Pacific`. Still fairly audible by 1355 but fading down, a sesquihour after sunrise here (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. 3308-USB, Sept 29 at 1153, AFA5ML is NCS for an Air Force MARS net, which is now ``free`` allowing random comments about the weather (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. WORLD OF RADIO 1897 monitoring: confirmed Thursday September 28 at 2330 on WBCQ, 9330.15v-CUSB, poor S4. Next:
Fri 2330 WBCQ 9330v-CUSB to WSW

(Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. 9955, Thu Sept 28 at 2030, a week after discovering the secret hour of WRMI programming, 20-21 UT, replacing Brother Scare, I check again, and here is `Frecuencia al Día`, replete with self-promotion, following some fill music, presumably after daily Radio Prague in English.
9955, Fri Sept 29 at 1309, no signal from WRMI, must be off, clearing the way for pulse jamming against nothing; 9455 & 9395 WRMIs are OK. 9955 still absent at 1355 and 1423 chex (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. 17775, Sept 29 at 1402, KVOH with distorted music and wobbling carrier, but not quite as bad as yesterday; S8-S9 but faded way down to S5 by 1419 (Glenn Hauser, OK, DX LISTENING DIGEST)
UNIDENTIFIED. Trans-Pacific JBA MW carrier search September 29 at 1209-1217, a few minutes before sunrise here, all from WSW, u.o.s: 774, 702, 828, 891, 1098-west, 1548 (Glenn Hauser, OK, DX LISTENING DIGEST)
UNIDENTIFIED. 860, Sept 29 at 1221 UT, Mexican music, ID over it as ``La Compera`` or something like that; DF from WSW/ENE which could put it in the US rather than Mexico. KNAI Phoenix? That`s Radio Campesina, and this word has only three syllables. At 1224 UT definite TC for 5:24 am = UT -7 zone, which means it has to be AZ, Sonora or BCN, as there are no such stations in CA or NV, and ``La Contrera`` (?), plug for Mexico City earthquake aid.
Sonora`s 860 is XEHX Ciudad Obregón, which is widely shown to be ``La Mia``. BCN`s is XEMO Tijuana, ``La Poderosa``. So have any of these changed name? (There is/was a La Campera on 1320 in Ciudad Jiménez, Chihuahua, XEJZ.) Initially atop KKOW KS, making 2.7 Hz SAH, and losing out to its weekdaily polka/birthday spot at 1226 UT (Glenn Hauser, OK, DX LISTENING DIGEST)
UNIDENTIFIED. 3385, Sept 29 at 1157, JBA carrier; could RENB, Rabaul be back on air? Also a JBA carrier on 3340, but both of them disappear when I switch from Preamp 2 to 1 on the R75, not the only strange carriers produced on 90m (Glenn Hauser, OK, DX LISTENING DIGEST)

356 PTT is Pratt KS, 341 EI is Enid OK of course, but no listing for 350 RG! (NOT to be confused with RG on 352 from Rarotonga!)
MARE Log Summary Aug 2017 reminds us that our RG is still on the air:
350 RG +1.0 -1.0 Oklahoma City OK, Will Rogers World A/P; 03 Apr (HF), 10 Sep (DT) (Glenn Hauser, Great Salt Plains OK, DX LISTENING DIGEST)
** OKLAHOMA. 1040, Sept 28 driving by the transmitter site of KGWA 960, twice, just west of it on north-south Oakwood Road, I am tuned to one of its spur frequencies, and observe that only at quite close range, it is strongest and clearly audible in noise, just to the north, but a null to the west despite being closest to the 4-tower parallelogram there, thus matching roughly the daytime direxional pattern on 960 itself, NNW/SSE to favor the rest of Enid and incidentally OKC beyond, where it can hardly be missed tuning between WKY and KTOK (if anyone ever does that any more). KGWA spur also on 880 making a SAH with KRVN Lexington NE, plus and minus almost exactly 80 kHz; why? (Glenn Hauser, Enid, DX LISTENING DIGEST)
** OKLAHOMA. 1360 & 1420, Sept 28 at 1858 UT, the KCRC 1390 Enid spurs are still audible out of town at Helena, making slightly different hets against real 1360 and 1420 stations; but not the second-order ones on 1330 and 1450 I can hear in town (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. 1090, Sept 28 at 1854 UT, Catholic Radio discussing whether this one or 1190 has a better signal in certain areas, during apparent fundraiser. 1090 is KEXS Excelsior Springs MO, the highest-frequency KC-market station to make it here on midday groundwave, 472 km = 293 miles. Has a CP (no longer merely an APP) for increase from 8 to 10 kW daytime, same pattern with major lobe WSW but broad enough for some of that to the SW (Glenn Hauser, Helena OK, DX LISTENING DIGEST)
** U S A. 1130, Sept 28 at 1857 UT, from this angle too still no audible daytime signal from KLEY Wellington KS. Its 250 watts are either off, or extremely direxional away from OK (Glenn Hauser, Helena OK, DX LISTENING DIGEST)
** U S A. 1150, Sept 28 at 1856 UT, I am bandscanning on caradio near Helena OK, NW of Enid. This frequency mainly bears KSAL Salina KS, but underneath is C&W music making a fast SAH. The latter could either be 1000-watt KNED McAlester OK, 289 km = 179 miles, or 530-watt KOLJ Quanah TX (across the SW corner of OK), virtually equidistant at 284 km = 176 miles; both with C&W formats and all three of them non-direxional daytime (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. 1370, Sept 28 at 1859 UT, still no signal audible from KGNO Dodge City KS. Can`t believe it`s funxioning at 5 kW ND which should be making it on daytime groundwave across the Ogallala Aquifer, only 205 km = 127 miles. Is it gone, QRP, or really out of whack direxional away? (Glenn Hauser, Helena OK, DX LISTENING DIGEST)

** U S A. 92.9, Sept 28 at 1920 UT, only thing of interest on an FM bandscan is weak signal in Spanish mixing with weak signal in English. Per WTFDA FM Database, no OKies on 92.9 are SS, but one Kansan:
KMML, (// KSMM 101.5), 92.9, CIMARRON KS, 32.0 kW H&V, 186.0 m HAAT, 37-56-30, 100-18-44, Spanish, REGIONAL MEXICAN, LA MEXICANA. Cimarrón is between Dodge and Garden Cities, 232 km = 144 miles (Glenn Hauser, Helena OK, DX LISTENING DIGEST)
UNIDENTIFIED. 659, Sept 28 at 1900 UT, The Answer 660 in The Metroplex has QRM from a carrier 1 kHz below it which cuts on for 5 seconds, off for 1 second, repeats. Loops east/west. Not coming from my car or anything in it, and not noted anywhere else. Not a harmonic from LW as nothing like it circa 330, 220 or 165 kHz. I`m parked at the military monument just south of Helena OK with three antique tanx, not looping toward them either.

Published on Thursday September 28, 2017 at 1500 UTC
Solar Space & Geomagnetic Weather Conditions on Wednesday September 27, 2017-
Solar activity had been low.
Earth's geomagnetic field had been at a major geomagnetic storming level.
The three daily solar flux index (SFI) numbers had been 88.9 91.0 89.1.
The official daily sunspot number (SSN) had been at 35.
In 2017 officially there were 56 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 unusually early.
In 2016 officially there were 32 days with a daily sunspot number (SSN) of 0.
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.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Officially there had been 3 earth facing sunspot groups (SSG).
Sunspot group (SSG) #12681 was located near S14W20 with an alpha magnetic signature. It was capable of producing a small in size C class solar flare.
Recurrent sunspot group (SSG) #12682 (ex #2673) was located near S11E33 with an alpha simple magnetic signature. It was capable of producing a small in size C class solar flare.
Sunspot group (SSG) #12683 was located near N12E48 with an alpha simple magnetic signature. It was capable of producing a small in size C class solar flare.
There had been no unofficial and as of yet unnumbered earth facing sunspot group (SSG).
There had been no returning (recurrent) sunspot group.
There had been 1 small in size C class solar flare. It was a
C1.7.
There had been no directly earth aimed (geoeffective) coronal mass ejection (CME).
There had been no partially earth aimed coronal mass ejection (CME).
There had been no directly (geoeffective) or partially earth aimed coronal mass ejection (CME) D layer ionosphere involved high latitude energetic proton storm >10 MeV (10+0).
The high latitude absorption via earths over ionized D layer is called polar cap absorption. The mid latitude absorption is caused by energetic electrons and protons spiraling down earth’s magnetic field lines into the equatorial ring current.
There had been no earth aimed solar flare related x-ray day side D layer involved solar fade out (SFO).
There had been no directly earth aimed (geoeffective) or partially earth aimed collapsing magnetic filament eruption.
The 24 hour period 3 hour interval planetary K index (Kp) had been at moderate geomagnetic storming to unsettled geomagnetic conditions of
3 3 4 4 4 3 5 6.
The 24 hour period 3 hour interval Boulder, CO K index had been at minor geomagnetic storming to quiet geomagnetic conditions of
3 2 4 4 3 3 5 4.
The K(p) 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) had ranged between
80 and 12,
which was at major geomagnetic storming to unsettled 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 maximum background x-ray flux had been at C1.7.
The 24 hour period maximum southward swing of the vertical component (Bz) of earth's geomagnetic magnetic field had been at approximately
-10 nT south.
The larger the negative value the further south-north that visible aurora can possibly be observed outside of the polar regions.
The 24 hour period maximum and minimum disturbance storm time index (Dst) had ranged between
-108 and -24 nT.
The -108 number equated to strong geomagnetic storming conditions.
The 24 hour period maximum and minimum solar wind speed ranged had ranged between
710 and 318 km/s.
There was 1 recurrent large in size trans equatorial earth facing coronal hole (CH) #826 (#822).
It’s attached high speed solar wind stream (HSS) was impacting earth’s geomagnetic field in a negative manner in the form of minor to major geomagnetic storming conditions.

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.

The 24 hour period 3 hour interval planetary K index (Kp) had been at moderate geomagnetic storming to unsettled geomagnetic conditions of
3 3 4 4 4 3 5 6.
The 24 hour period 3 hour interval Boulder, CO K index had been at minor geomagnetic storming to quiet geomagnetic conditions of
3 2 4 4 3 3 5 4.
The K(p) 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) had ranged between
80 and 12,
which was at major geomagnetic storming to unsettled 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 maximum background x-ray flux had been at C1.7.
The 24 hour period maximum southward swing of the vertical component (Bz) of earth's geomagnetic magnetic field had been at approximately
-10 nT south.
The larger the negative value the further south-north that visible aurora can possibly be observed outside of the polar regions.
The 24 hour period maximum and minimum disturbance storm time index (Dst) had ranged between
-108 and -24 nT.
The -108 number equated to strong geomagnetic storming conditions.
The 24 hour period maximum and minimum solar wind speed ranged had ranged between
710 and 318 km/s.
There was 1 recurrent large in size trans equatorial earth facing coronal hole (CH) #826 (#822).
It’s attached high speed solar wind stream (HSS) was impacting earth’s geomagnetic field in a negative manner in the form of minor to major geomagnetic storming conditions.

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.

** GERMANY. 15449.880, Sept 27 at 1502, JBA carrier way off-frequency, once again presumed IBB Biblis site as scheduled for R Liberty in Tajik. Wolfgang Büschel checked a bunch of other Biblis frequencies and found them all within a few Hz of nominal.
15449.874, Sept 28 at 1403, JBA carrier now measured here, gone by 1442 check. Today Wolfgang Büschel also has it:
``Hi, yes, - I've got it today on Thur Sept 28: 15449.881 kHz exact measured at S=9+20dB signal level on remote SDRs at Athens Greece and Doha Qatar ME. RL Tajik program service. Before 1359 UT heavy signal spill-over from Trincomalee CLN 15430 kHz, 40 kHz wideband signal, I guess. 1359:04 Biblis transmitter switched on air crash, 3rd try to start, - each second and sudden breaks from 1359:01 UT. At 1400:00 UT exact switched to RL Tajik audio feed. vy73 de wolfie`` (Glenn Hauser, OK, DX LISTENING DIGEST)
** MADAGASCAR. 17640, Sept 27 at 2025, MWV is VG but with deep rolling fades during African Pathways Radio, promoting Christianity to the Heathens. Too bad they won`t include any Rational programming. The two English hours at 18 & 20 UT are now back in season to reach the opposite worldside so well, better than anything else on 16m, except possibly KVOH, q.v. (Glenn Hauser, OK, DX LISTENING DIGEST)
** NEW ZEALAND. 6224-USB, Sept 28 at 1235, NZ coastal weather by robot clearly enunciating each word, which sounds inhuman without normal inflexions, but better readability than some mumbling software other stations use attempting to sound more natural. It`s ZLM, Taupo Maritime Radio, but on the air at a time EiBi shows it to be in a break: 32 minute transmissions starting at 1003 and not again until 1333 (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. 7489.89v-AM, Sept 27 at 2335, WBCQ with an `Allan Weiner Worldwide` repeat to fill an hour, reminiscing about FCC pirate bust against his Yonkers AM & FM stations on August 12, 1971. Slot vacated by `The Next Chapter`, but if you want to follow Radio Alexandria, the project to broadcast from a ship in the central Pacific, check
http://www.radioalexandria.net/about
where podcasts are available, and nothing about quitting WBCQ (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. 17775, Sept 28 at 1442, KVOH is S9+30 but heavy distortion, sounds horrible; carrier also wobbling and splattering out to 17763-17877. When will they *ever* get their replacement transmitter going? (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. 990, Sept 28 at 1226 UT, after failing to pull an ID from a station in English inviting local PSAs, un-nulling the Spanish which is certainly KFCD Farmersville TX, one of the Metroplex stations which hijacked a frequency from poor Wichita Falls: gospel harmonies in Spanish, promo preaching event Sept 30 in Area Code 214, ``tres ángeles`` codeword for that 7D Adventist sect, two IDs in passing, the next at 1231, sound like ``Radio Movimiento`` but not positive about the word. Maybe program rather than station name. Can`t find any correlation online with KFCD, but rather surely unrelated: Radio Movimiento, KPCN-LP 95.9 FM, Portland OR, which is secular about Hispanicism (Glenn Hauser, OK, DX LISTENING DIGEST)
** YEMEN [non]. 11860, Sept 27 at 1437, Republic of Yemen Radio reception improving, husky singing in Arabic, S9 to S9+10 presumably via somesite in SA`UDI ARABIA (Glenn Hauser, OK, DX LISTENING DIGEST)

Global Daily HF Radio Wave Propagation Forecast-
We are now entering the fall/spring equinox type of HF radio wave propagation conditions. Globally HF radio wave propagation conditions are most evenly balanced across the equator during the fall and spring equinox.
HF radio wave propagation conditions trend- deteriorating.
Northern Hemisphere Radio Wave Propagation Forecast-
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.
Meters conversion to frequency in mHz-
Hamateur & SWL bands

12- 24.89-24.99
11- 25.6-26.1
10- 28.0-29.7
During the northern hemisphere winter season the higher HF bands of 10-20 meters (11-19 meters) close sooner due to less sun light illuminating the ionosphere than in the southern hemisphere. But the maximum useable frequency (MUF) is higher than in the southern hemisphere as the F layer of the ionosphere is lower in height and more dense.
Southern Hemisphere Radio Wave Propagation Forecast-
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,

12- 24.89-24.99
11- 25.6-26.1
10- 28.0-29.7
Keep in mind that almost daily during the southern 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).

This HF Radio wave propagation forecast is produced based on the SIGINT_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 general public.
And though this HF radio wave propagation forecast is produced based on the SIGINT_CAP, I do check the actual band conditions at my location in the USA and tweak the forecast manually where and when necessary. I also check global HF radio wave propagation conditions via remoted radio receivers around on every continent of the globe and tweak the forecast manually 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 high gain 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.

Keep in mind that almost daily during the southern 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).

This HF Radio wave propagation forecast is produced based on the SIGINT_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 general public.
And though this HF radio wave propagation forecast is produced based on the SIGINT_CAP, I do check the actual band conditions at my location in the USA and tweak the forecast manually where and when necessary. I also check global HF radio wave propagation conditions via remoted radio receivers around on every continent of the globe and tweak the forecast manually 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 high gain 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.

The BBC Launches Korean Language News: A New Option for North Korean Radio Listeners
On September 25, the BBC launched its Korean-language service, adding another voice to radio stations already targeting North Koreans with news and information.
BBC Korea is part of a major expansion of BBC language services and comes after a grassroots campaign to get the BBC on air alongside South Korea’s KBS and two US networks: Voice of America and Radio Free Asia. A handful of religious broadcasters also target North Korea as does South Korea’s National Intelligence Service.
Officially, the BBC says its broadcasts are intended for the “Korean peninsula”—no doubt an attempt to partially deflect complaints from the North Korean government—but there is little doubt of who the real target is.
So, will anyone listen and will it do any good?
There’s no reliable way to measure radio audiences in the country and the authorities aggressively attempt to jam foreign broadcasts, but there is evidence that North Koreans are tuning in to broadcasts from overseas.
Defectors have talked of listening to overseas broadcasts, some crediting the programs with helping them make up their minds whether to defect. As with any data based on defector interviews, the sample is skewed to people who were dissatisfied with their government and, in many cases, lived near the border where overseas radio reception is easier, but that is the best data we have.
Much of the listening happens late at night, when atmospheric propagation helps radio signals travel further distances and when people can secretly listen at home with less chance of being discovered.
A 2010 survey carried out by the Broadcasting Board of Governors, which oversees Voice of America and Radio Free Asia, found audiences began climbing at 9:00 PM local time and spiked in the 11:00 PM to midnight hour.[1] More than half of the entire survey group reported listening each hour between 11:00 PM and 1:00 AM.
And so the BBC’s Korean service is broadcasting from midnight until 3 AM Pyongyang time. The full broadcast is carried on two shortwave frequencies, from Taiwan and Tashkent, and the middle hour is relayed on mediumwave, from Mongolia.
Mediumwave is more common than shortwave on North Korean radios, so it’s a smart choice, but the signal from Mongolia will be weak by the time it reaches Pyongyang. Shortwave signals will be stronger, but the BBC still faces a battle in getting a good signal into North Korea.
As listening to foreign radio is illegal, the government makes a great effort to prevent people from doing so. At the most basic level, it modifies radios so they cannot be tuned into anything but state-run channels, although that can be later reverse engineered.
A much bigger problem is radio jamming, where loud noise is deliberately broadcast over a foreign station to make it difficult or impossible to listen to.
On its first evening of broadcasts to North Korea, both BBC shortwave channels were aggressively targeted.
It wasn’t possible to evaluate whether the mediumwave channel was also targeted.
Despite the jamming, foreign broadcasters think it’s worth continuing. Radio, while not as sexy as smuggled soap operas on USB sticks, remains the only way that up-to-date news can be quickly sent into North Korea. While broadcasters have shifted to satellite TV and the Internet in targeting other countries, North Korea remains stuck in the 1980s in terms of options.
North Koreans that do listen to foreign radio are keen consumers of information.
A 2012 study by InterMedia found elite listeners relied on foreign broadcasts as a key source of external information and analytical reporting.
In its first night on air, BBC Korea carried news and sports that was more broadly focused than the fare found on U.S.-broadcasters. The Korean service has its own team of reporters but also draws on the global newsgathering resources of the BBC, so alongside an interview with Ban Ki Moon, there was a report on the German elections, the Kurdish independence vote and a possible eruption of a volcano in Indonesia. The news ended with a weather forecast for North Korea.
There’s also an “essential English conversation” language learning program, offering lessons such as: “Hi, my name is Phil. Nice to meet you.” Such educational programming could help differentiate the BBC from other broadcasters that are more focused on news or North-South issues.
Beyond the people tuning in, the information carried on such broadcasts can also have a second life when it is relayed to others. The 2010 BBG study found just over two out of five people said they passed on news and information from foreign broadcasts to their friends and neighbors. Just over a quarter confessed to sharing it with family members and a third of people, illustrating the risk involved, said they shared it with no-one.
InterMedia’s report found that more than three quarters of all foreign radio listeners were in their 30s and 40s. Two thirds lived in urban areas and counted South Korean stations as their most-trusted source of information (32%), followed by foreign stations in Korean (16%).
Some of the BBC’s Korean language output is also available on the Internet:bbc.com/korean.
Broadcast frequencies for the radio programs are 5810 kHz and 9940 kHz shortwave and 1431 kHz mediumwave. From October 28, 2017, until March 24, 2018, the shortwave broadcasts will be carried on 5810 kHz and 5830 kHz. (38north.org)
Glenn Hauser logs September 27, 2017
** BOLIVIA. 5935.01, Sept 27 at 2356, finally I have a JBA carrier, after no-shows 24 and 48 hours earlier from presumed Radio Yura; slightly on hi side, with traces of modulation until blasted away by WWCR steel drums from *2358:50 (Glenn Hauser, OK, DX LISTENING DIGEST)
** CHINA. 11785, Sept 27 at 2338, Firedragon music jamming over something in Chinese, S7 peaks with flutter. Can`t tell whether the Chinese is ours, RFA this hour only via Tinian, or theirs, CNR1 jamming to boot.
9830, Sept 27 at 2345, weak signal, at first suspected Turkey in German as sometimes by mistake, but it`s not off-frequency and it`s in Chinese, so scratch that; instead, CNR1 at 2025-0100, 100 kW, 175 degrees from Beijing 572 site, per NDXC, and not a jammer! There are lots of other weak Chinese signals scattered around 31mb now.
9765, Sept 27 at 2347, YL in Cambodian with piano music background. NDXC/Aoki shows it`s CRI this hour only in Khmer, 100 kW, 200 degrees from Nanning 954 site.
9535, Sept 27 at 2349, music under RHC music sounds like Firedragon: this hour only, jamming is required vs RFA Chinese via Kuwait. 9535 is always one of the weakest RHC channels here (Glenn Hauser, OK, DX LISTENING DIGEST)
** EAST TURKISTAN. 5960, Sept 28 at 0000, time-signal ending with last pip higher about half a second late, JBA signal, maybe Chinese. Per NDXC, only here is PBS Xinjiang, at 2300-0257, 100 kW ND from Urumqi. This is the station which could QRM The Mighty KBC on UT Sundays, and used to be off-frequency low when also heard in our mornings, but don`t notice that now. Got to hurry back to PBS for The Vietnam War (Glenn Hauser, OK, DX LISTENING DIGEST)
** OKLAHOMA. 88.3, Sept 26 at various chex, Family Radio satellator in Enid, K202BY is back on air. I last logged it in mid-May but it was gone again by Mayend. Clearly a low priority, not unusual to be gone for months at a time, and glad it is, as otherwise 88.3 is my best lowband frequency for DX and for RF feeders in the car and house. Fortunately it`s weak enough for the feeders to overcome it in most circumstances (Glenn Hauser, Enid, DX LISTENING DIGEST)
** PERU. 5980, Sept 27 at 2329 I`m tuned in earlier to catch R. Chaski cutoff since I missed it last night due to periodic reset of autotimer. Yes, JBA carrier now until 2330:06.5* approx.; unfortunately I glanced away from my watch when it vanished, so subtracted a couple of seconds. This is now the reference point for future slippage circa 6.7 seconds later per noctem (Glenn Hauser, OK, DX LISTENING DIGEST)
** SOUTH CAROLINA [non]. 9395, Sept 27 at 2351, preview of Pope Francis` visit to Philadelphia coming up Sept 22-27, 2015, including Saturday Sept 26 and Sunday 27, for the World Meeting of Families; quite positive coverage, so wonder what this be: Overcomer, as soon confirmed by numerous //s on WRMI and other stations not synchronized such as 9370 WWRB. I thought BS is anti-Catholic? Maybe he is just playing this so as to denounce it following (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. Re 14336-USB, ``Frontier Red Willow``, Art Jackson, KA5DWI/7 in AZ replies in ABDX: ``That frequency is active for County Hunters. It has been for many many years. There are other frequencies used, but that is a common calling frequency by those out in rarer counties. The phonetics was a ham call, but he must have failed to give his prefix. It is a common practice to ask for relays when one side is weak. I use to do that when travelling through west, south and central Texas counties back in my younger days. I should do it now that I am retired. 73`` (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. WORLD OF RADIO 1897 monitoring: confirmed Wednesday September 27 at 1045 amid the 1030 broadcast on WRMI, 5850, S9+20, but JBA carrier only on presumed // 9455, weaker than some Asian on 9460 (however, circa 0610, I was surprised to find WRMIs 9395 & 9455 unusually still holding up with VG signals). 1897 also confirmed Wed Sept 27 at 1315 on WRMI, 9955, S9+10 but with pulse jamming; tnx a lot, Arnie! It worsened some by 1320.
WOR also confirmed at surprise new secret time, Wed Sept 27 at 2039 on WRMI, 9955! So we get the Wed 2030 slot in the expanded WRMI programming hour instead of BS; fair, but pulse jamming continues, and ramps up by 2100; tnx a lot, Arnie.
NOT confirmed Wed Sept 27 at 2100 on WBCQ, 7490: fair signal but dead air from first check 2041 past 2100 and 2129, yet the dulcet tones of Goddess Irina have resumed by 2146. WOR barely confirmed Wed Sept 27 at 2330 on WBCQ, 9329.95v-CUSB, S6 including noise level, much weaker than usual here. Next:

Solar Space & Geomagnetic Weather Conditions
on Tuesday September 26, 2017-
Solar activity had been
moderate.
Earth's geomagnetic field had been at a minor
geomagnetic storming level.
The three daily solar flux index (SFI) numbers had
been 90.2 90.7 90.0.
The
official daily sunspot number (SSN) had been at 40.
In 2017 officially there were 56 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 unusually
early.
In 2016 officially there were 32 days with a daily
sunspot number (SSN) of 0.
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.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Officially there had been 3 earth facing sunspot
groups (SSG).
Sunspot
group (SSG) #12681 was located near S13W07 with a beta magnetic signature. It
was capable of producing a small in size C class solar flare and an isolated
medium in size M class solar flare.
Recurrent
sunspot group (SSG) #12682 (ex #2673) was located near S11E47 with an alpha
simple magnetic signature. It was capable of producing a small in size C class
solar flare.
Sunspot
group (SSG) #12683 was located near N12E61 with with an alpha simple magnetic
signature. It was capable of producing a small in size C class solar
flare.
There
had been 1 unofficial and as of yet unnumbered earth facing sunspot group (SSG)
located near
S09W12.
There
had been no returning (recurrent) sunspot group.
There
had been 1 small in size C class solar flare. It was a
C1.8.
There
had been no directly earth aimed (geoeffective) coronal mass ejection (CME).
There had been no partially earth aimed coronal
mass ejection (CME).
There had been no directly (geoeffective) or
partially earth aimed coronal mass ejection (CME) D layer ionosphere involved
high latitude energetic proton storm >10 MeV (10+0).
The high latitude absorption via earths over
ionized D layer is called polar cap absorption. The mid latitude absorption is
caused by energetic electrons and protons spiraling down earth’s magnetic field
lines into the equatorial ring current.
There had been no earth aimed solar flare related
x-ray day side D layer involved solar fade out (SFO
There had been no directly earth aimed
(geoeffective) or partially earth aimed collapsing magnetic filament
eruption.
The 24 hour period 3 hour interval planetary K
index (Kp) had been at quiet geomagnetic conditions of
1 1 1 1 0 0 0 2.
The 24 hour period 3 hour interval Boulder, CO K
index had been at quiet geomagnetic conditions of
0 0 2 1 1 2 1 2.
The K(p) 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) had ranged between
7 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 maximum background x-ray flux
had been at C1.76.
The 24
hour period maximum southward swing of the vertical component (Bz) of earth's
geomagnetic magnetic field had been at approximately
-17 nT south.
The larger the negative value the further
south-north that visible aurora can possibly be observed outside of the polar
regions.
The 24 hour period maximum and minimum disturbance
storm time index (Dst) had ranged
between
-47
and +27 nT.
The 24 hour period maximum and minimum solar wind
speed ranged had ranged between
411
and 275 km/s.
There
was 1 recurrent large in size trans equatorial earth facing coronal hole (CH)
#826 (#822).
It’s
attached high speed solar wind stream (HSS) was impacting earth’s geomagnetic
field in a negative manner in the form of minor geomagnetic storming
level.

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.
