W4HM Solar Cycle 24 Update and Solar Cycle 25 Forecast- Short and to the point.

Solar minimum may begin later this year and may last longer than any previous solar cycle in the 20th century. When solar cycle 25 finally gets underway it could be the weakest since the middle of the 19th century. Another Dalton type lesser grand solar minimum may occur with a corresponding cooling of earth’s climate. This would negate anthropogenic climate change if it were occurring which it isn’t.

On February 1, 2008 I forecasted that solar cycle 24 would be the smallest solar cycle in the past 100 years. That forecast verified. I also forecasted that solar cycle 25 would be almost non nonexistent.

#8 issued Tuesday January 8, 2019 at 1600 UTC

Important Solar, Space & Geomagnetic Weather Indices-

Solar activity was very low.

The daily solar flux index numbers (DSFI) were

72.3 71.5 71.2.

There had been 7 consecutive days with a 2000 UTC daily solar flux index number (SFI) above 70.

Unfortunately daily SFI numbers in the 70’s doesn’t increase ionization via ultraviolet light striking the F2 layer, to raise the maximum usable frequency (MUF) high enough to activate the 15, 12 and 10 meter bands along east-west radio wave propagation paths.

The official daily sunspot number (DSSN) was 0.

There had been 2 consecutive days with a daily sunspot number (DSSN) of 0.

In 2018 there had been 221 days with an official daily sunspot number (DSSN) of 0.

There had been no geo effective (earth facing) sunspot group(s).

The 24 hour period 3 hour interval planetary K index (Kp) had been at a quiet geomagnetic condition of

1 1 2 2 2 2 2 2.

The 24 hour period planetary A index (Ap) maximum and minimum values ranged between

10 & 0,

which had been at a quiet geomagnetic condition.

The 24 hour period maximum and minimum Disturbance Storm Time Index (Dst) ranged between

-15 & +3 nT.

The 24 hour period maximum and minimum solar wind speed was

481 & 420 km/s.

GLOBAL (HF) HIGH FREQUENCY (3000-30000 KHZ) RADIO WAVE PROPAGATION CONDITIONS EXPECTED-

HF-MF radio wave propagation condition “trend” on Jan 8, 2019- steady.

HF-MF radio wave propagation condition “trend” on Jan 9, 2019- steady.

HF-MF radio wave propagation condition “trend” on Jan 10, 2019- steady.

Northern Hemisphere HF Radio Wave Propagation Forecast g-

We are now in the winter season northern hemisphere HF-MF radio wave propagation season.

The approximate 11000- 30000 kHz frequency range closes 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 the ions more concentrated.

The approximately 3000-10000 kHz frequency range often stays open for DX all throughout the day due to a weaker D and E layer and therefore less RF signal absorption.

Northern Hemisphere Radio Wave Propagation Forecast g-

3150-3400, 3500-4100, 4750-5050, 5700-6300 kHz- S9 +1 to 9 at night and S1-3 at day,

6900-7800, 9200-9995, 10000-10150, 11500-12200 kHz- S9+ 1 to 9 at night and
S4-7 at day,

13570-13850, 14000-14350, 15005-15900, 17450-17950, 18068-18168 kHz- S0 at night and S3-4 at day,

21000-21850 kHz- S0 at night and S1-2 at day,

24890-24990, 25600-26100 kHz- S0 at night and S1 at day,

28000-29700 kHz- S0 at night and S0 at day.

Southern Hemisphere HF Radio Wave Propagation Forecast g-

We are now in the summer season southern hemisphere HF-MF radio wave propagation season.

The 14000- 30000 kHz frequency range closes later due to more sun light illuminating the ionosphere than in the southern hemisphere. But the maximum usable frequency (MUF) is lower than in the southern hemisphere as heating in the F2 layer of the ionosphere is higher and the layer ions less concentrated.

Almost daily during the northern hemisphere summer season you will find that the 25600- 26100 kHz and 28000-29700 kHz frequency ranges 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).

3150-3400, 3500-4100, 4750-5050, 5700-6300 kHz- S9+10 at night and S3-5 at day,

6900-7800, 9200-9995, 10000-10150, 11500-12200 kHz- S9+15 at night and
S4-7 at day,

13570-13850, 14000-14350, 15005-15900, 17450-17950, 18068-18168 kHz- S1-3 at night and S5-8 at day,

21000-21850 kHz- S0 at night and S1-2 at day,

24890-24990, 25600-26100 kHz- S0 at night and S1 at day,

28000-29700 kHz- S0 at night and S0 at day.

This HF-MF Radio wave propagation forecast is produced based on the SIGINT_CAP HF-MF radio wave propagation prediction software.

I wrote it beginning in the late 1980’s but I’m sorry to say that it still can’t be distributed to the general public. It does outperform VOA CAP and Prop Lab.

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-MF radio wave propagation conditions via remoted radio

receivers on every continent of the globe and tweak the forecast manually if

and when necessary.

And last but not least I look at ionsonde stations on every continent of the

globe.

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.

The MF broadcast band AM Mode RF signal levels are based on 50,000 watts (50 kw) and an omnidirectional vertical antenna.

Please keep in mind that this is a relatively simplified HF-MF radio wave

propagation forecast, so as to keep it easily understandable and applicable

by the average radio enthusiast.

THE FOLLOWING IS EDUCATIONAL MATERIAL ON SOLAR, SPACE, GEOMAGNETIC WEATHER OBSERVING AND IONOSPHERE GOINGS ON. ALSO HF AND MF RADIO WAVE PROPAGATION CONDITIONS AND FORECASTING.

Globally HF-MF 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). Also by propagation path.

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.

Lower high frequency (80-30 meters) propagation conditions are impacted in a

negative manner not so much by variations in the maximum usable frequency

(MUF) along a particular propagation path and time but rather due to

geomagnetic elevated geomagnetic conditions (Kp-3-4), storms (Kp-5 &

greater) that increase signal absorption via the E layer (the altitude of

the radio aurora). Also increases in the lowest usable frequency (LUF) via D

layer RF signal absorption due to hard x-rays, galactic cosmic waves,

elevated background solar flux levels greater than B0 and energetic proton

flux levels at energies greater than 10 MeV (10+0).

Higher frequency (20-10 meters) propagation conditions are impacted in a

negative manner by variations in the maximum usable frequency (MUF) along a

particular propagation path and time due to the current sunspot number and

also due to elevated geomagnetic conditions (Kp-3-4), storms of Kp-5 &

greater. Also D layer RF signal absorption due to elevated (greater than B0)

background solar flux levels. Also to a lesser extent elevated proton flux

at energies greater than 10 MeV (10+0).

GENERAL GUIDELINES CONCERNING CORRELATION OF PROPAGATION INDICES TO ACTUAL HF PROPAGATION CONDITIONS-

NOTE!!! The propagation indices "interpretations" are my personal

intellectual property. Therefore the HF-MF radio wave propagation indices

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 (HF) radio wave propagation possible,

something that happens only 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.

GENERAL GUIDELINES CONCERNING CORRELATION OF PROPAGATION INDICES TO ACTUAL MF PROPAGATION CONDITIONS-

Medium frequency (300-3000 khz) radio wave propagation conditions are impacted in a negative manner not by variations in the maximum usable frequency (MUF) along a particular propagation path and time but rather due to energetic electron flux levels at energies greater than 2 MeV (2+1), geomagnetic disturbances (Kp-3-4) and geomagnetic storms (Kp-5 & >) that increase signal absorption via the E layer (the general altitude of the radio aurora). Also increases in the lowest usable frequency (LUF) via D layer signal absorption due to elevated background solar flux levels greater than A0, proton flux levels at energies greater than 10 MeV (10+0), hard x-rays and galactic cosmic rays.

There is also the issue of magneto ionic power coupling. Antenna polarization plays a large role in the success of a long haul MF DX contact. As a MF RF signal traverses Earth's magnetic lines of force in a perpendicular manner on high and mid latitude paths say between W3 land and SM, higher angle horizontally polarized signals are more readily absorbed than lower angle vertically polarized signals. On other propagation paths on the globe opposite results can be found, i.e., horizontally polarized signals suffer less absorption on a propagation path between VK6 and W6 or S9 and W4.

Unfortunately the simplest way to look at medium frequencies with respect to radio wave propagation conditions is to accept the fact that propagation is poor the majority of the time, especially past approximately 1250 miles (one maximum distance refraction off of the E layer), with occasional short-lived good periods as far as 3200 miles.

All 13 of the following indices have to occur as described below in order to see the best global medium frequency (MF) radio wave propagation possible.

1.) Dropping geomagnetic field indices numbers are better, Kp of 0 best.

2.) A daily sunspot number under 100, under 70 best.

3.) A daily sunspot number no higher then the 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 proton flux levels no greater than 10 MeV (10+0).

7.) Background x-ray flux levels of A0 for several days consecutively.

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.) Galactic cosmic rays decrease to -3 units below zero and trending towards zero.

12.) Energetic electron flux levels no greater than 2 MeV (2+0).

13. A solar wind speed of less than 300 km/s for several days consecutively.

Highlights of Solar and Geomagnetic Activity
31 December - 06 January 2019

Solar activity was at very low levels on 31 Dec - 05 Jan and
increased to low levels on 06 Jan due to an isolated C1 flare at
06/1051 UTC from Region 2732 (N09, L=215, class/area Cao/090 on 03
Jan). No Earth-directed CMEs were observed during the period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at
normal levels on 05 Jan and normal to moderate levels on 01-04 Jan.
High levels were observed on 31 Dec and 06 Jan due to enhancements
associated with recurrent coronal hole high speed streams (CH HSS).
The largest flux of the period was 2,020 pfu observed at 31/1930
UTC.

Geomagnetic field activity ranged from quiet to G1 (Minor) storm
levels. Solar wind parameters began the period under a waning
positive polarity CH HSS. Solar wind speed decreased from
approximately 520 km/s on 31 Dec to 290 km/s by 03 Jan with total
field at or below 6 nT. The geomagnetic field was at quiet to
unsettled levels on 31 Dec - 01 Jan while quiet levels were observed
on 02-03 Jan. At approximately 04/0420 UTC, total field began to
increase to a maximum of 13 nT at 04/1705 UTC which was indicative
of the arrival of a CIR preceding a negative polarity CH HSS. The Bz
component reached a maximum southward deflection of -9 nT at 05/0200
UTC. Solar wind speed increased to a maximum of 565 km/s at 06/1350
UTC. The geomagnetic field responded with mostly unsettled periods
late on 04 Jan, quiet to G1 (Minor) storm levels on 05 Jan, and
quiet to unsettled levels on 06 Jan.

Forecast of Solar and Geomagnetic Activity
07 January - 02 February 2019

Solar activity is expected to be at very low levels on 07-19 Jan
with a chance for C-flare activity on 20 Jan - 02 Feb due to the
return of old Region 2732 (N09, L=215).

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at high levels on 07-12 Jan, 25-27 Jan and again on
02 Feb due to recurrent CH HSS influence.

Geomagnetic field activity is expected to reach unsettled levels on
07, 26 and 31 Jan. Unsettled to active levels are expected on 16
Jan, 24-25 Jan and 01-02 Feb. G1 (Minor) levels are likely on 24
Jan. Levels of elevated geomagnetic activity are anticipated due to
recurrent CH HSS effects.

W4HM Solar Cycle 24 Update and Solar Cycle 25 Forecast- Short and to the point.

#7 issued Monday January 7, 2019 at 1530 UTC

Important Solar, Space & Geomagnetic Weather Indices-

Solar activity was very low.

The daily solar flux index numbers (DSFI) were

72.4 72.0 72.1.

There had been 6 consecutive days with a 2000 UTC daily solar flux index number (SFI) above 70.

The official daily sunspot number (DSSN) was 0.

There had been 1 day with a daily sunspot number (DSSN) of 0.

Prior to that there had been 5 consecutive days with an official daily sunspot number (DSSN) greater than 0.

In 2018 there had been 221 days with an official daily sunspot number (DSSN) of 0.

There had been one sunspot group numbered 12732 but it set around the west limb of the sun.

The 24 hour period 3 hour interval planetary K index (Kp) had been at an unsettled to quiet geomagnetic condition of

2 3 3 2 2 2 3 2.

The 24 hour period planetary A index (Ap) maximum and minimum values ranged between

15 & 6,

which had been at an unsettled to quiet geomagnetic condition.

The 24 hour period maximum and minimum Disturbance Storm Time Index (Dst) ranged between

-17 & -5 nT.

The 24 hour period maximum and minimum solar wind speed was

540 & 447 km/s.

GLOBAL (HF) HIGH FREQUENCY (3000-30000 KHZ) RADIO WAVE PROPAGATION CONDITIONS EXPECTED-

HF-MF radio wave propagation condition “trend” on Jan 7, 2019- improving.

HF-MF radio wave propagation condition “trend” on Jan 8, 2019- improving

HF-MF radio wave propagation condition “trend” on Jan 9, 2019- steady.

Northern Hemisphere HF Radio Wave Propagation Forecast g-

We are now in the winter season northern hemisphere HF-MF radio wave propagation season.

The approximately 3000-10000 kHz frequency range often stays open for DX all throughout the day due to a weaker D and E layer and therefore less RF signal absorption.

Northern Hemisphere Radio Wave Propagation Forecast g-

28000-29700 kHz- S0 at night and S0 at day.

Southern Hemisphere HF Radio Wave Propagation Forecast g-

We are now in the summer season southern hemisphere HF-MF radio wave propagation season.
