W4HM Daily HF Radio Wave Propagation Forecast #2018-114

Greetings to my fellow hamateur radio and SWL radio enthusiasts around the
world.

Welcome to my “not for profit” daily W4HM Daily HF Radio Wave Propagation
Forecast.

It’s the only daily global HF radio wave propagation forecast produced on
the planet.

I'm a retired heliophysicist, terrestrial meteorologist/climatologist and
one of the few on the planet with advanced education and forecast
experience in both disciplines. In terrestrial weather forecasting I have 45
years of experience and in space weather 34 years.

Important Solar, Space & Geomagnetic Weather Indices-

The daily solar flux index numbers (DSFI) were 74.7 72.9 72.6

There had been 7 days in a row with a 2000 UTC daily solar flux index number
(DSFI) greater than 70.

The official daily sunspot number (DSSN) was 19.

There had been 6 days in a row with a daily sunspot number (DSSN) greater
than 0.

In 2018 there had been 67 days with a daily sunspot number (DSSN) of 0.

Sunspot group #12706 was located near N02E01 with a relatively simple beta
magnetic signature capable of releasing a very small B class solar flare and
an isolated small in size C class solar flare.

The 24 hour period 3 hour interval planetary K index (Kp) had been at a
quiet geomagnetic condition of 1 0 1 0 1 1 2 2.

The 24 hour period maximum and minimum solar wind speed ranged between 352 &
328 km/s.

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. It does outperform VOA CAP.

And though this HF radio wave propagation forecast is produced based on the
SIGINT_CAP software, 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 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.

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). 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
wave propagation conditions in a negative manner.

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 radio wave propagation indices
interpretations contained herein is copyrighted © 1988-2018 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.

SAQ on Air on May 1st

World Heritage Grimeton Radio Station participates in the ERIH event WORK it OUT – Industrial culture, on May 1 and as part of the event we plan for the first SAQ transmission since 2016.

The transmitter start-up will begin at 11.30 (9.30 UTC) and the transmission will begin on 17,2 kHz CW at 12.00 (10.00 UTC). You can also watch a live video stream of the event on www.alexander.n.se

No QSL-cards will be given this time and no List of Reports will be constructed but we accept shorter Listeners Report to e-mail info@alexander.n.se.


We sincerely hope that all the SAQ transmission on 17,2 kHz will go as planned, but as always there is a reservation that the transmission is cancelled with short notice.

Glenn Hauser logs April 23-24, 2018

** CUBA [and non]. 15140, April 23 at 1758 on caradio, RHC is already on in tail of Spanish, tnx to sloppyraters; and with a SAH of about 2 Hz; 1800 opening RHC Arabic vs music from understation Radio Sultanate of Oman, a long-standing collision. Something`s always wrong at RHC (Glenn Hauser, OK, DX LISTENING DIGEST)

** CUBA. 11985-12015 approx., horrible distorted blob of S9+20/30, and this time enough modulation to match it by AM tuning to RHC Spanish on 11840, 11760, 11860. This is not a mixing product, but an attempt to broadcast normally on scheduled 12000. The blob seems to peak about 12002, but no specific center carrier. Cf my previous unID, which was certainly this. Something`s always wrong at RHC (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 410 kHz, April 23 at 0534 UT, ND beacon EGQ, which is 25 watts from Emmetsburg, Iowa (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. WORLD OF RADIO 1926 monitoring: gone again from WBCQ 9330v-CUSB, Monday April 23 at 2330, instead Brother keeps Scaring // 5130v. I suppose WOR is the last left variation from all-BS-all-the-time on 9330, since Blalock was moved to 7490; so it`s hit-and-miss, whether anyop will break away for a semihour of WOR, which did occur again 24 hours earlier. WOR confirmed UT Tuesday April 24 at 0030 on WRMI, 7730, good. 

This week I plan to start WOR 1927 at its earliest possible time, unless some unforseen delay intervene:

Full WOR sked on all outlets, podcast access:
http://www.worldofradio.com/radioskd.html
(Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 7570, April 23 at 0521, WRMIBS is off this night, in keeping with scheduled closure at 0500 on new sked, despite running way past that the night before.

5985, April 23 at 0524, American English gospel huxter at S9 --- it`s WRMI, which per transmission skedgrid is airing only at 0330-0430 daily, but Mondays only like this, extended to 0600. There is no System A yellow program schedule below it to tell us who this is. HFCC as of April 11 does not account for the extension, but does show CRI in Arabic via Albania starting at 0500 daily, bit of which we can normally hear without WRMI.

9455 // 9955, Monday April 23 at 1348, WRMI in a new episode of `Viva Miami`, Jeff interviewing someone in English at a Ft Lauderdale event about the cruise industry around Japan. Jeff has quite a sideline(?) as a cruise promoter. Tuesday at this block it`s Famagusta instead.

7570 and 5950, April 24 at 0603 are both off now as scheduled (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 7505v, April 23 at 0521, WRNO is on with low modulation, altho was not on by 0100+. Must have started late (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 3215, April 23 at 0532, WWCR-1 is off, despite scheduling 0100-0900. And it`s not because of deleted BS either, variety of programming on the outdated program sked, as of March 1, still showing 6-hour difference between UT and CT. 4840 and 5935 are still on and audible despite degraded propagation. If on, 3215 should remain inbooming, best of all overnight (Glenn Hauser, OK, DX LISTENING DIGEST)

UNIDENTIFIED. 5055.978, April 24 at 1241, JBA carrier. Could 4KZ Australia be off-frequency? Nothing on 5055.0 and this trace is about what I used to hear there. Also noticed yesterday but not logged or measured. Could be local device, but not here previously (Glenn Hauser, OK, DX LISTENING DIGEST)

UNIDENTIFIED. 15054.5-USB, April 24 at 1313, big racket of background engine noise, on colloquial Spanish 2-way; first words recognized, ``puta madre``, en contacto with much weaker ``Juanito, cambio``. Still something there at 1353 (Glenn Hauser, OK, DX LISTENING DIGEST)

W4HM Daily HF Radio Wave Propagation Forecast #2018-113

Greetings to my fellow hamateur radio and SWL radio enthusiasts around the
world.

Welcome to my “not for profit” daily W4HM Daily HF Radio Wave Propagation
Forecast.

It’s the only daily global HF radio wave propagation forecast produced on
the planet.

I'm a retired heliophysicist, terrestrial meteorologist/climatologist and
one of the few on the planet with advanced education and forecast
experience in both disciplines. In terrestrial weather forecasting I have 45
years of experience and in space weather 34 years.

Created and disseminated by Thomas F. Giella, W4HM in Lakeland, FL, USA ©
1988-2018.

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. It does outperform VOA CAP.

And though this HF radio wave propagation forecast is produced based on the
SIGINT_CAP software, 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 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.

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). 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
wave propagation conditions in a negative manner.

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 radio wave propagation indices
interpretations contained herein is copyrighted © 1988-2018 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.

Environment Center, other U.S. government entities and educational
institutions, to produce this daily HF radio wave propagation
forecast. This data is gathered and made public by the U.S. Government using

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. It does outperform VOA CAP.

And though this HF radio wave propagation forecast is produced based on the
SIGINT_CAP software, 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 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.

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). 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
wave propagation conditions in a negative manner.

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 radio wave propagation indices
interpretations contained herein is copyrighted © 1988-2018 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.

** U S A. WORLD OF RADIO 1926 monitoring: confirmed, restored to 2330 UT on WBCQ 9330v-CUSB: Sunday April 22 good signal on 9329.9v-CUSB. 

Also confirmed UT Monday April 23 at 0130:30 on WRMI, S9+40 on 5850, S9-S5 on 7780 --- but third frequency 5950 is off. It had been on before 0100 with Eslovaquia; at 0050 no longer with the big SAH, but still trace of another signal, presumably Iran. Also confirmed UT Mon Apr 23 from 0300:30 on Area 51 webcast, and until 0329:30 on WBCQ 5129.8v. JBA UT Mon Apr 23 at 0330 on WRMI 9955, but definitely on webcast. And still repeating immediately from 0400 on webcast only, a full schedule for which is not available. More below about WRMI`s new schedule display. Next:

** U S A. Checking http://www.tinyurl.com/WRMIfqs I see that the program skedgrid below the transmission skedgrid has been completely reorganized! --- now it`s System by color-coded System, each of which will be on a variety of frequencies depending on the time. This is more explicit than before. But it would still be helpful to have a separate schedule sorted by frequency. Otherwise you have to hunt thru the Systems for a particular frequency and time.

WORLD OF RADIO times are as before, including the new one Sunday at 1900 on 9395, and the almost-new one Monday at 0130 on 5850, (5950-not), 7780. AND, still allegedly Saturday 2300 on 7780, while VORW has really been airing.

Now there`s a better view of System G - Oldies, and all the variations from that. But strangely, shows RAE in German M-F at 19-20 UT on 9395, but Italian M-F at 20-21 UT on 9455. Yet System D shows 20-21 UT with variety programming on 9455 and 7780, including WOR Tuesday at 2030 as before. 9455 can`t be on both Systems at once. 

NOTE that System G and System B (mainly 9955) are displayed in EDT!! While the others are in UT. It`s still not 100% accurate compared to monitoring, e.g. Overcomer really running beyond 0500 on 7570 as heard last night (Glenn Hauser, OK, DX LISTENING DIGEST) 

** U S A. 7490, April 23 at 0107, WBCQ with Blalock the Blaster; 9330 with Brother Scare; 5130 with Area 51 music (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 5050, UT Mon Apr 23 at 0055, still no signal from WWRB nor anywhere on 90m. 15240 also missing earlier, so maybe just totally off, whatever the nominal scheduling may now be (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 7505v, April 23 at 0107, still no signal from WRNO (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. No one asked, but anyhow, I left one number out of the URL for recording of KLEY Wellington KS; should have a 1 after SNAFU as I anticipate adding a 2: how it sounded April 20 when tuned to 1129-USB:

UNIDENTIFIED. 11990-12007 approx., April 23 at 0113, huge distorted blob peaking about 12000, S9+10, cannot make out any rational modulation in AM or FM modes. Maybe Cuba. RHC is OK on 11840, 11760, 11700, 11670 (Glenn Hauser, OK, DX LISTENING DIGEST)

Highlights of Solar and Geomagnetic Activity 16 - 22 April 2018

Solar activity was very low. Region 2706 (N03, L=281, class/area
Dao/130 on 22 Apr) produced the strongest flare of the period, a B5
at 20/1704 UTC. The region continued slow growth through the end of
the reporting period. 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 ranged
from normal to high levels on 10-20 Apr; high levels on 22 Apr and
moderate to high levels for the remaining days of the reporting
period. The peak flux observed was 24,100 pfu at 21/2120 UTC.

Geomagnetic field activity was quiet until 20 Apr, when unsettled to
G2 (Moderate) geomagnetic conditions were observed in response to
CIR ahead of a negative polarity CH HSS. Total field peaked at 23 nT
around 20/0510 UTC and slowly declined to around 5 nT by late on 20
Apr. Solar wind speeds were increased from around 290 km/s to a peak
of near 620 km/s during the HSS proper late on 20 Apr. The
geomagnetic response decreased to quiet to unsettled conditions over
21 Apr and finally to quiet on 22 Apr as influence from the CH HSS
waned.

FORECAST OF SOLAR AND GEOMAGNETIC ACTIVITY 23 APRIL - 19 MAY 2018

Solar activity is expected to be very low throughout the forecast
period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at moderate to high levels on 23-30 Apr and 07-19
May; normal to moderate levels are expected from 01-06 May. Elevated
levels of electron flux are expected due to the anticipation of
multiple, recurrent CH HSSs.

Geomagnetic field activity is expected to reach unsettled levels on
26 Apr, 06 May, 09-10 May and 19 May; active levels are expected on
27 Apr, 07-08 Apr and 18 May; G2 (Moderate) geomagnetic storm
conditions are likely on 17 May. All enhancements in geomagnetic
field activity are associated with the anticipated influence of
multiple, recurrent CH HSSs. The remaining days of the outlook
periods are expected to be mostly quiet.

Despite being announced Radio City program, 1800-1900, third Friday of the month, Radio City did not go to air. I contacted whit the station about this, and here is the answer:
"Dear Manuel,
It sometimes happens IRRS finds other customers for the Friday evening slot. The 3rd Saturday on 9510 kHz is guaranteed and if there is no other customers repeats of old programmes may be repeated other Saturdays.Radio City was on the air yesterday on 9510 kHz as announced.

W4HM Daily HF Radio Wave Propagation Forecast #2018-111

Greetings to my fellow hamateur radio and SWL radio enthusiasts around the
world.

Welcome to my “not for profit” daily W4HM Daily HF Radio Wave Propagation
Forecast.

It’s the only daily global HF radio wave propagation forecast produced on
the planet.

I'm a retired heliophysicist, terrestrial meteorologist/climatologist and
one of the few on the planet with advanced education and forecast
experience in both disciplines. In terrestrial weather forecasting I have 45
years of experience and in space weather 34 years.

Created and disseminated by Thomas F. Giella, W4HM in Lakeland, FL, USA ©
1988-2018.

If you find this daily HF radio wave propagation forecast useful to your
hamateur and SWL radio activities, feel free to drop me a line and let me
know that at

thomasfgiella@gmail.com

I enjoy hearing from other fellow radio enthusiasts.

Hams and SWLs that are interested in solar, space & geomagnetic weather as
well as radio wave propagation are a special group of people interested in
broadening their knowledge in science.

Important Solar, Space & Geomagnetic Weather Indices-

The daily solar flux index numbers (DSFI) were 76.0 76.8 75.3


There had been 4 days in a row with a 2000 UTC daily solar flux index number
(DSFI) greater than 70.

The official daily sunspot number (DSSN) was 31.

There had been 3 days in a row with a daily sunspot number (DSSN) greater
than 0.

In 2018 there had been 67 days with a daily sunspot number (DSSN) of 0.

Sunspot group #12706 was located near N03E43 with a relatively simple beta
class magnetic field capable of releasing a very small B class solar flare
and an isolated small in size C class solar flare.

Sunspot group #12707 was located near S09E31 with a simple alpha class
magnetic field capable of releasing a very small A class solar flare and an
isolated very small in size B class solar flare.

The 24 hour period 3 hour interval planetary K index (Kp) had been at a
quiet to unsettled geomagnetic condition of 3 2 3 2 2 3 2 3.

The 24 hour period maximum and minimum solar wind speed ranged between 650 &
530 km/s.

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. It does outperform VOA CAP.

And though this HF radio wave propagation forecast is produced based on the
SIGINT_CAP software, 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 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.

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). 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
wave propagation conditions in a negative manner.

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 radio wave propagation indices
interpretations contained herein is copyrighted © 1988-2018 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.
