Propagation News – 30 April 2017

Last week saw some unsettled conditions due to the effects of a coronal hole. Its associated high speed solar wind stream actually hit the Earth a day earlier than predicted, resulting in poor HF conditions during the International Marconi Day event on Saturday, 21 April.

The planetary K-index hit six the night before and we were left with noisy bands and poor propagation. HF openings were predominantly to Europe, although Australia and the US were worked by GB0CMS from Caister in Norfolk. While conditions improved slightly through the week the K-index remained steadfastly high.

There were highlights though. The A25UK Expedition to Botswana was worked from the UK on bands as high as 10 metres. As this is a North-South path, signals didn’t have to go through the unsettled auroral oval.

There were a couple of sunspots that helped push the solar flux index to more than 80, but next week NOAA predicts the SFI will be around the mid to high 70s, with unsettled geomagnetic conditions at times. The K-index could hit five on Bank Holiday Monday, but then decline to three or four for the rest of the week.

We should soon start to see the start of the sporadic E season, which may bring good short-skip opportunities on the upper HF bands. Keep an eye on the 10 metre beacons from around 28.150 to 28.330MHz for openings.

VHF and up:

Low pressure will bring showery rain into western Britain later in the weekend, with prospects for GHz bands rain scatter. This will soon be replaced by a ridge of high pressure extending south from a large high over Scandinavia. The ridge may bring the possibility of some tropo conditions towards the east across the North Sea.

That said, the quite strong easterly wind over southern areas may not be the best for good tropo, since it is likely to be a dry flow and thus there may not be a good moisture contrast between the surface and the dry air above any temperature inversion. If tropo turns out to be not such a strong player, there are good reasons to hope for some sporadic E as we move into the first week of May. This is usually regarded as the start of the main sporadic E season, so the main periods to check are late morning and late afternoon.

As we said earlier, start with 10m and then move higher in frequency as any opening develops. The openings can eventually reach 2m.

Moon declination is high and losses still low this weekend but declination falls and losses increase as the week progresses.


A week today, before dawn, the Eta Aquarids meteor shower peaks, but the shower’s radiant never gets very high above the horizon for observers in the Northern Hemisphere.

Glenn Hauser logs April 25-26-27, 2017

** KUWAIT. 15540, April 26 at 1821, presumed R. Kuwait in English, VP S6 signal vs line noise level of S4-S5. I`m keeping after the electric company to fix it, and in fact they are back here working on it circa 1530 April 27 (Glenn Hauser, OK, DX LISTENING DIGEST)

** MEXICO. 800, April 27 at 1200 UT, XEROK with choral NA, near-local KQCV OKC nulled as much as possible. This time I can copy enough of the full ID which follows at 1202 to tell that Radio Cañón with street address is *not* mentioning an FM frequency with a seven in it, but instead after 800, they say ``Grupo 7`` (Glenn Hauser, OK, DX LISTENING DIGEST)

** MEXICO. 6185, April 26 at 1832, JBA carrier but the SSOB vs even weaker 6070 CFRX carrier exactly at local mean noon here. Detectable despite line noise level, and have previously found it later in afternoon. Presumed XEPPM, Radio Educación, México DF at some 1180 miles, which supposedly does not sign on until 2300. It`s definitely not on circa sunrise when never heard tho better propagable, so when do they turn it on and is it just carrier or with programming // MW 1060? Someone in the RGV might be able to tell which (Glenn Hauser, OK, DX LISTENING DIGEST)

** NORTH AMERICA. 7615-AM, April 27 at 0456, Station YHWH is on but VP, gone at next check 0514 (Glenn Hauser, OK, DX LISTENING DIGEST)

** OKLAHOMA. RF channel A-48 NTSC, April 27 at 1500 UT, I`m monitoring snow again in case I can get KOCY-LP OKC, the Estrella TV station. Maps show tropo is slightly enhanced over central OK. Yes! At *1506 video flashes on the air, but gone again in a few seconds. This keeps happening, at *1507, *1508, *1510, *1513, each lasting well less than a minute. But nothing more in 20+ minutes after that. While on, it`s steady, and the cuts on and off are sharp/abrupt. There is no lightning around, and the steady signal, no Doppler fading, means it`s not Vance airplane scatter either. 

Therefore I conclude that like also monitored some weeks ago, this transmitter is axually off the air most of the time, but cuts on briefly and unpredictably. After the first flash, I bring up KTUZ-DT RF 29, which has the same silly program (`El Show de Lagrimita y Costel`, featuring La Silla Eléctrica), on its virtual 48 and confirm it matches altho not synchronized. RF 48 remains the last such station on analog air around here (sporadically). It`s totally superfluous for the OKC audience of course, with the high-power DTV version of same available without breaks (Glenn Hauser, Enid, DX LISTENING DIGEST)

BS on 7490 supposedly runs only until 0700* (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 15555-USB, April 26 at 1822, WJHR with usual gospel huxter, at S5 about the same as the line noise level. Many other times during the day it`s inaudible, hard to be sure if on air or not, but it`s no 50 kW (Glenn Hauser, OK, DX LISTENING DIGEST)

UNIDENTIFIED. 7575.8-USB, April 27 at 0515, 2-way in tonal? Language, or maybe 1-way with pauses; far too close to the BS out of 7570 WRMI (Glenn Hauser, OK, DX LISTENING DIGEST)

Global Daily HF Radio Wave Propagation Forecast-

HAMATEUR & SW BROADCAST HF BANDS:


HF radio wave propagation conditions are slowly improving.


NORTHERN HEMISPHERE RADIO WAVE PROPAGATION-

80-60 (75-60) meters- good at night and poor at day,

40-30 (41-25) meters- good at night and fair at day,

20-17 (22-15) meters- very poor at night and good at day,

15 (13) meters- very poor at night and fair to good at day,

12 (11) meters- very poor at night and fair at day.

10 (11) meters- very poor at night and poor to fair at day.


SOUTHERN HEMISPHERE RADIO WAVE PROPAGATION-

80-60 (75-60) meters- good at night and poor at day,

40-30 (41-25) meters- good at night and fair at day,

20-17 (22-15) meters- very poor at night and good at day,

15 (13) meters- very poor at night and fair to good at day,

12 (11) meters- very poor at night and fair at day.


Received RF signal strength scale-

Very Good- +1 over S9 Or Greater
Good- S7-9
Fair- S4-6
Poor- S1-3
Very Poor- S0

Meter Band Equivalents
Ham & SWL
160->   90
80->     75
60->     60
40->     49, 41
30->     31, 25
20->     22, 19
17->    16, 15
15->    13
12,10-> 11

The SSB RF signal levels received are based on 100 watts and ½ wave dipole
up at 40 feet for hamateur radio.

The AM signal levels on the HF shortwave broadcast bands are based on
100,000 watts (100 kw) and a typical 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 also change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the
ecliptic, as well as by radio wave frequency. This is due to changes in the
maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2).

The D and E layers also come into play through RF radio wave signal
absorption and refraction. And then there is sporadic E (Es) radio wave
propagation that can really throw a wrench into the gears so to speak.

Things like sporadic E (Es) radio wave propagation and lightning storm
static can impact HF radio wave propagation in an unpredictable manner and
mostly bad.

Ongoing solar, space and geomagnetic weather goings on also impact HF radio
wave propagation conditions in a negative manner.

---------------------------------------------------------------------------------------------

Solar, Space & Geomagnetic Weather Conditions On

Wednesday April 26, 2017-

Solar activity was low.

Earth's geomagnetic field was at an unsettled level.

The three daily solar flux index (SFI) numbers were 81.7 79.6 78.5.

---------------------------------------------------------------------------------------------------------------------

The official daily sunspot number (SSN) was 36.

In 2017 officially there were 30 days with a daily sunspot number (SSN) of
0.

Considering that solar minimum won't occur for approximately 2 more years,
+/- 1 year, observations daily SSN's of 0 occurring now is unusually early.

In 2016 officially there were 32 days with a daily sunspot number (SSN) of
0. Considering that solar minimum won't occur for approximately three more
years, seeing daily SSN's of 0 occurring now is unusually early.

As we move forward towards the next solar minimum between solar cycle #24
and #25 the number of days with a 0 daily SSN will steadily increase.
Eventually every day for many, many, many months will see a 0, the big goose
egg.

In 2008 I forecasted solar cycle 24 to be the weakest in the past 100 years
and that forecast verified. I also forecasted that solar cycle 25 would be
virtually nonexistent, similar to the Dalton type solar minimum that
occurred in the early 1800's. It will probably be very difficult to
determine when solar cycle 24 ended and solar cycle 25 began.

---------------------------------------------------------------------------------------------------------------------


The twenty four hour period 3 hour interval planetary K index (Kp) was at
unsettled to quiet geomagnetic conditions of

3 1 2 1 2 2 2 2.

The Kp geomagnetic indices are-
0-2- quiet
3- unsettled
4- active
5- minor geomagnetic storming
6- moderate
7- strong
8- severe
9- extreme
10- our atmosphere just got cooked off like on Mars and we are all dead.

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

12 and 5,

which was at unsettled to quiet geomagnetic conditions.

The Ap geomagnetic indices are-
0-7- quiet
8-15 unsettled
16-29- active
30-49- minor geomagnetic storm
50-99- major
100-400- severe
>401- our atmosphere just got cooked off like on Mars and we are all dead.

The daily averaged background x-ray flux was at B4.96.

The daily averaged vertical component (Bz) of earth's magnetic field was at
+0.84 nT north.

The 24 hour period maximum and minimum disturbance storm time index (Dst)
ranged between

-20 and -38 nT.

The 24 hour period maximum and minimum solar wind speed ranged between

568 and 451 km/s

and was directly connected by a high speed solar wind stream to recurrent
southern hemisphere earth facing (CH) coronal hole #802 (#798).

CH #802 (#798) produced moderate (Kp-6) geomagnetic storming during its last
trip across the earth facing side of the sun and has done so this time
around also.

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

NOTE!!! The propagation indices "interpretations" are my personal
intellectual property. Therefore the radio wave propagation indices
interpretations contained herein is copyrighted © 1988-2017 by Thomas F.
Giella, W4HM, all rights reserved. Reproduction of information herein is
allowed without permission in advance as long as proper credit is given.

All 14 of the following indices have to occur as described below in order to
see the best global high frequency radio wave propagation possible,
something that happens rarely.

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

2.) A daily sunspot number of 150 or higher, 200 or higher best.

3.) A daily sunspot number of greater than 100 for routine stable formation
of the E Valley/F Layer ducting mechanism.

4.) Previous 24 hour Ap index under 10, fewer than 7 for several days
consecutively are best.

5.) Previous 3 hours Kp index fewer than 3 for mid latitude paths, fewer
than 2 for high latitude paths, 0 for several days consecutively is best.

6.) Energetic protons no greater than 10 MeV (10+0).

7.) Background x-ray flux levels greater than B1 for several days
consecutively, greater than C1 best.

8.) No current STRATWARM alert.

9.) Interplanetary magnetic field (IMF) Bz with a (positive number) sign,
indicates a lesser chance of high latitude path aurora
absorption/unpredictable refraction or scattering of medium frequency RF
signals, when the Kp is above 3.

10.) A -10 or better towards a positive number Dst index during the recovery
time after a geomagnetic storm, as related to the equatorial ring current. A
positive number is best.

11.) Rising positive T index number. The T Index tracks with the F2 layer
critical frequency (foF2) and sunspot number (SSN) and indicates the
capability of the F2 layer to refract RF signals.

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

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

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

Global Daily HF Radio Wave Propagation Forecast-

HAMATEUR & SW BROADCAST HF BANDS:


HF radio wave propagation conditions are improving.


NORTHERN HEMISPHERE RADIO WAVE PROPAGATION-

80-60 (75-60) meters- good at night and poor at day,

40-30 (41-25) meters- good at night and fair at day,

20-17 (22-15) meters- very poor at night and good at day,

15 (13) meters- very poor at night and fair to good at day,

12 (11) meters- very poor at night and fair at day.

10 (11) meters- very poor at night and poor to fair at day.


SOUTHERN HEMISPHERE RADIO WAVE PROPAGATION-

80-60 (75-60) meters- good at night and poor at day,

40-30 (41-25) meters- good at night and fair at day,

20-17 (22-15) meters- very poor at night and good at day,

15 (13) meters- very poor at night and fair to good at day,

12 (11) meters- very poor at night and fair at day.


Received RF signal strength scale-

Very Good- +1 over S9 Or Greater
Good- S7-9
Fair- S4-6
Poor- S1-3
Very Poor- S0

Meter Band Equivalents
Ham & SWL
160->   90
80->     75
60->     60
40->     49, 41
30->     31, 25
20->     22, 19
17->    16, 15
15->    13
12,10-> 11

The SSB RF signal levels received are based on 100 watts and ½ wave dipole
up at 40 feet for hamateur radio.

The AM signal levels on the HF shortwave broadcast bands are based on
100,000 watts (100 kw) and a typical 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 also change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the
ecliptic, as well as by radio wave frequency. This is due to changes in the
maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2).

The D and E layers also come into play through RF radio wave signal
absorption and refraction. And then there is sporadic E (Es) radio wave
propagation that can really throw a wrench into the gears so to speak.

Things like sporadic E (Es) radio wave propagation and lightning storm
static can impact HF radio wave propagation in an unpredictable manner and
mostly bad.

Ongoing solar, space and geomagnetic weather goings on also impact HF radio
wave propagation conditions in a negative manner.

---------------------------------------------------------------------------------------------

Solar, Space & Geomagnetic Weather Conditions On

Tuesday April 25, 2017-

Solar activity was low.

Earth's geomagnetic field was at an unsettled level.

The three daily solar flux index (SFI) numbers were 81.6 81.3 80.1.

---------------------------------------------------------------------------------------------------------------------

The official daily sunspot number (SSN) was 36.

In 2017 officially there were 30 days with a daily sunspot number (SSN) of
0.

Considering that solar minimum won't occur for approximately 2 more years,
+/- 1 year, observations daily SSN's of 0 occurring now is unusually early.

In 2016 officially there were 32 days with a daily sunspot number (SSN) of
0. Considering that solar minimum won't occur for approximately three more
years, seeing daily SSN's of 0 occurring now is unusually early.

As we move forward towards the next solar minimum between solar cycle #24
and #25 the number of days with a 0 daily SSN will steadily increase.
Eventually every day for many, many, many months will see a 0, the big goose
egg.

In 2008 I forecasted solar cycle 24 to be the weakest in the past 100 years
and that forecast verified. I also forecasted that solar cycle 25 would be
virtually nonexistent, similar to the Dalton type solar minimum that
occurred in the early 1800's. It will probably be very difficult to
determine when solar cycle 24 ended and solar cycle 25 began.

---------------------------------------------------------------------------------------------------------------------


The twenty four hour period 3 hour interval planetary K index (Kp) was at
unsettled to quiet geomagnetic conditions of

3 2 2 2 3 2 2 2.

The Kp geomagnetic indices are-
0-2- quiet
3- unsettled
4- active
5- minor geomagnetic storming
6- moderate
7- strong
8- severe
9- extreme
10- our atmosphere just got cooked off like on Mars and we are all dead.

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

15 and 7,

which was at unsettled to quiet geomagnetic conditions.

The Ap geomagnetic indices are-
0-7- quiet
8-15 unsettled
16-29- active
30-49- minor geomagnetic storm
50-99- major
100-400- severe
>401- our atmosphere just got cooked off like on Mars and we are all dead.

The daily averaged background x-ray flux was at B7.25.

The daily averaged vertical component (Bz) of earth's magnetic field was at
-2.84 nT south.

The 24 hour period maximum and minimum disturbance storm time index (Dst)
ranged between

-21 and -50 nT.

The 24 hour period maximum and minimum solar wind speed ranged between

666 and 463 km/s

and was directly connected by a high speed solar wind stream to recurrent
southern hemisphere earth facing (CH) coronal hole #802 (#798).

CH #802 (#798) produced moderate (Kp-6) geomagnetic storming during its last
trip across the earth facing side of the sun and has done so this time
around also.

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.

Galbeni maintenance

"The Galbeni short-wave transmitters relaying Radio Romania International broadcasts are undergoing technical revision on Thursday, April 27, between 09.00 and 17.00 hours, Bucharest time (06.00-14.00 GMT), according to schedule. In the aforementioned time span, you can listen to our broadcasts relayed by the Tiganesti transmitters on short-wave, online at www.rri.ro, or on mobile apps that can be downloaded from Google Play and App Store, as well as on your fixed and mobile phone (in Romania, the US Italy, Spain, France and Great Britain)."

AIR demonstrates capabilities of DRM

As part of Phase II of the DRM introduction in the country, AIR is demonstrating the full complement of services which are part of the DRM standard. Recently AIR was congratulated by Hon’ble Union Minister for Information and Broadcasting Shri Venkaiah Naidu for having successfully completed phase-I of the national DRM digital radio roll-out – the installation of 37 DRM transmitters, now operational, throughout the country. AIR is in the process of launching phase-II of the DRM project by offering full features/services from these DRM transmitters and further improving service quality. With the finalization of phase-II, the fullfeatured DRM services will finally be available to the audience and a public information campaign will be initiated to inform the Indian citizens of the completely new and future oriented DRM radio platform and its many benefits. 

The first steps of phase-II of the digital radio roll-out project are already visible and audible to the audience in Delhi. The DRM transmissions from Delhi/Nangli now provide excellent audio quality based on DRM’s xHE-AAC audio codec. It also includes DRM text messages and Journaline. The advanced text service Journaline provides detailed news of various topics to listeners – accessible on their radio set screen – free of charge, without requiring Internet access. All this is available in the simulcast configuration and with the most robust DRM transmission configuration, enabling increased in-door coverage. 

21 DRM transmitters are now operating in pure DRM for one hour everyday, in addition to simulcast operation. Excellent feedback is being received by AIR about of the reception quality of DRM signals. AIR is planning to enhance the DRM service from Chennai, Pune and Bangalore very shortly.

Glenn Hauser logs April 24-25, 2017


** INDONESIA. 9525-, April 24 at 1423 check, VOI absent again today, no carrier detectable (Glenn Hauser, OK, DX LISTENING DIGEST)

** JAPAN [non]. 11985, April 24 at 2029, S9-S6 open carrier, 2030 NHK World R. Japon opening in French via MADAGASCAR. At least something is making it thru with rather dismal propagation conditions, marred further here by my line noise problem (Glenn Hauser, OK, DX LISTENING DIGEST)

** OKLAHOMA [and non]. 91.1 FM, April 24 at 1717 UT check, KKRD Enid, 200-watt station, is still off the air as first noted three days ago following a storm. Still off April 25. Its antenna is on the Broadway Tower in downtown Enid. Once a respected office building, new owners got it for a song and were trying to convert it into a hotel, but now it`s decrepit, with both elevators padlocked! Maybe no one wants to climb the stairs (14? floors) to restart the transmitter? Part of the external facing cracked off last year, and just recently there was a fire in a transformer just outside the building.

This opens 91.1 for 100 kW stations in Wichita KS, KCFN, with AFR, and in Lawton OK, KJRF, another gospel huxter, but not heard yet, both in 100+ mile range. And much to be preferred, 100 kW High Plains Public Radio, KANZ Garden City KS, but just too far on internal antennas.

90.9, KOKF Edmond OK is still on with Air One contemporary Christian music, rather than the talk show I logged before, 1717 UT April 24.

89.1, K206CA, Enid, Oasis Network translator of 90.5 KNYD (or really 88.1 KMSI??) has been restored after running dead air at last check.

92.1, KAMG-LP, Enid remains off the air as of April 25. Last heard carrier on March 10, no modulation for a long time before then. WTFDA DB now shows its horizontal and vertical powers both as 0.0 kW, certainly appropriate.

104.7, KQSN, Ponca City, April 24 at 1903 UT, ID as ``KQSN, Ponca City, Sunny 104.7`` and *one* minute of Fox News until 1904 resuming music.

105.5, K288FX, North Enid, K-love translator of KYLV 88.9, is still off the air April 25, as first noticed April 21 after storms (it`s really in East Enid).

105.7, KRDR Alva, 50 kW now easily heard with 105.5 local off, is no longer ESPN, but hard rock/rap, April 24 at 1900 UT, ``We are The Pulse. . .`` and K-calls not copied. April 25 at 1546 UT: ``The Pulse, 105.7 FM``

WTFDA DB identifies it with sibling? station: ``COYOTE COUNTRY 98.3 KQZQ``. Radio-locator shows: ``KRDR-FM 105.7 MHz Alva, Oklahoma "ESPN Radio 105.7" Format: Sports Website: none``

But google search leads to this:
which has nothing but current sports news on it

Also to this FB, but nothing new since June 2016:

We would much prefer to hear on 105.7, KROU Spencer, public radio relay of KGOU Norman, but it`s only 1.6 kW, and can`t overcome KRDR until about Kingfisher on US 81 (Glenn Hauser, Enid, DX LISTENING DIGEST)

** U S A. WORLD OF RADIO 1874 monitoring: confirmed Monday April 24 at 2330 on WBCQ 9330.35v-CUSB, good. Also confirmed UT Tuesday April 25 at 0030 on WRMI, 7730, VG S9+20. Also barely confirmed Tuesday April 25 at 1114 the 1100 broadcast on WRMI 9955; at least it sounds like me, mixed with equally weak pulse jamming. Still no 9455. Next:
Tue 2130   WRMI 15770 to NE, 9455? to WNW
Tue 2330   WBCQ 9330v-CUSB to WSW
Wed 1030   WRMI 5850 to NW, 9455? to WNW

Wed 2330   WBCQ 9330v-CUSB to WSW
Note: 9455 is still not activated as of April 25, and when it is, unclear whether will still be // 9955, 15770 and 5850 at above WOR times like former 6855 was (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 9455, April 24 at 1424 check, still no signal from WRMI-5, supposed to reactivate here ex-6855, altho we are well past ``next week`` (Glenn Hauser, OK, DX LISTENING DIGEST)

The official daily sunspot number (SSN) was 43.

In 2017 officially there were 30 days with a daily sunspot number (SSN) of
0.

Considering that solar minimum won't occur for approximately 2 more years,
+/- 1 year, observations daily SSN's of 0 occurring now is unusually early.

In 2016 officially there were 32 days with a daily sunspot number (SSN) of
0. Considering that solar minimum won't occur for approximately three more
years, seeing daily SSN's of 0 occurring now is unusually early.

As we move forward towards the next solar minimum between solar cycle #24
and #25 the number of days with a 0 daily SSN will steadily increase.
Eventually every day for many, many, many months will see a 0, the big goose
egg.

In 2008 I forecasted solar cycle 24 to be the weakest in the past 100 years
and that forecast verified. I also forecasted that solar cycle 25 would be
virtually nonexistent, similar to the Dalton type solar minimum that
occurred in the early 1800's. It will probably be very difficult to
determine when solar cycle 24 ended and solar cycle 25 began.

Recurrent sunspot group #12651 (#12644) was located near N11E08 with a
magnetically simple alpha signature.

Sunspot group #12652 was located near N12E02 with a magnetically simple beta
magnetic signature.

Sunspot group #12653 was located near S10E35 with a magnetically simple
alpha magnetic signature.

Unofficially there were no earth facing but as of yet unnumbered sunspot
group located near.

No earth facing C class or larger solar flares occurred.

No earth facing coronal mass ejections (CME) occurred.

No earth directed day side radio black outs occurred.

No earth directed collapsing magnetic filament eruptions occurred.

The twenty four hour period 3 hour interval planetary K index (Kp) was at
active to quiet geomagnetic conditions of

3 4 3 4 2 3 4 3.

The Kp geomagnetic indices are-
0-2- quiet
3- unsettled
4- active
5- minor geomagnetic storming
6- moderate
7- strong
8- severe
9- extreme
10- our atmosphere just got cooked off like on Mars and we are all dead.

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

22 and 7,

which was at active to quiet geomagnetic conditions.

The Ap geomagnetic indices are-
0-7- quiet
8-15 unsettled
16-29- active
30-49- minor geomagnetic storm
50-99- major
100-400- severe
>401- our atmosphere just got cooked off like on Mars and we are all dead.

The daily averaged background x-ray flux was at B2.68.

The daily averaged vertical component (Bz) of earth's magnetic field was at
-4.17 nT south.

The 24 hour period maximum and minimum disturbance storm time index (Dst)
ranged between

-24 and -54 nT.

The 24 hour period maximum and minimum solar wind speed ranged between

800 and 570 km/s

and was directly connected by a high speed solar wind stream to recurrent
(CH) coronal hole #802 (#798).

There was a recurrent southern hemisphere earth facing (CH) coronal hole
#802 (#798). It produced moderate (Kp-6) geomagnetic storming during its
last trip across the earth facing side of the sun and has done the same this
time around also.

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.

Highlights of Solar and Geomagnetic Activity 17 - 23 April 2017

Solar activity reached low levels on 17-18 Apr due to isolated
C-class flare activity from Region 2651 (N12, L=070,
class/area=Cso/150 on 23 Apr), but solar activity was at very low
levels through the remainder of the period (19-23 Apr). The largest
event of the period, a long-duration C5/Sf flare at 18/2010 UTC with
both Type-II and IV radio emissions, had an associated CME that was
observed in C2 coronagraph imagery beginning at 18/1948 UTC. CME
analysis and WSA-Enlil modelling suggested that this event did not
have an Earth-directed component, however, it is likely that this
event reached Earth late on 21 Apr. No other Earth-directed CMEs
were observed.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels on 17-18, 21-23 Apr, moderate levels on 20 Apr, and
normal levels on 19 Apr.

Geomagnetic field activity was quiet on 17 Apr and quiet to
unsettled on 18 Apr under a nominal solar wind regime. The influence
of a recurrent, positive polarity CH HSS caused periods of G1
(Minor) geomagnetic storm conditions on 19 Apr and G1-G2
(Minor-Moderate) storm conditions on 20 Apr. The likely arrival of a
CME (from 18 Apr) combined with the onset of a CIR caused G1 (Minor)
geomagnetic storm levels late on 21 Apr. The influence of a
recurrent, negative polarity CH HSS began early on 22 Apr and caused
G1-G2 (Minor-Moderate) geomagnetic storms on 22-23 Apr.

FORECAST OF SOLAR AND GEOMAGNETIC ACTIVITY 24 APRIL - 20 MAY 2017

Solar activity is expected to be very low with a chance for C-class
flare activity throughout the outlook period (24 Apr-20 May).

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
likely to reach very high levels on 29-30 Apr with high levels
likely on 24-28 Apr and 06-12, 17-20 May. Normal to moderate flux
levels are expected for the remainder of the period.

Geomagnetic field activity is likely to reach G2 (Moderate)
geomagnetic storm levels on 19-20 May with G1 (Minor) geomagnetic
storms likely on 24-27 Apr and 01, 17-18 May due to the influence of
multiple, recurrent CH HSSs. Active conditions are likely on 28 Apr
and 05-06, 16 May with quiet or quiet to unsettled field activity
expected for the remainder of the period.
