Glenn Hauser logs May 24-25, 2017


** ARGENTINA [non]. 7730, Thursday May 25 at 0602, Spanish song, but presumably still filling the Japanese hour from RAE without news during staff vacation. A sked received by Hansjoerg Biener from the German service May 16 showed the target for the 06 broadcast in Japanese as North America West rather than Asia North. 

11580, May 25 at 1300, WRMI goes from BS to RAE, Argentine vers le Monde, en français. Extremely informal rapid chat between two announcers, until starting Journal at 1302 which is also presented in same style. Lite QRM initially, maybe Sound of Hope and/or jamming. EiBi has KTWR in Vietnamese on 11580 until 1315 daily, but Aoki shows that on Saturdays only. 1328 ME music fill inserted by WRMI, own ID, and 1330 resuming RAE in French: not sure whether exactly same episode repeated. Yesterday at this time 11580 appeared to be off, but had returned by 1851 check May 24 with Brother Scare. The 14-15 WRMI hour on 11580 is still playing World Music when checked at 1409 May 25 (Glenn Hauser, OK, DX LISTENING DIGEST)

** CUBA. 6100, May 25 at 0554, RHC English here is a very poor signal instead of one of the best, so hard to evaluate modulation level. 6060 is strongest signal and audio. 6000 is undermodulated. 6145 is just barely modulated. 5040 is good (Glenn Hauser, OK, DX LISTENING DIGEST)

** KOREA NORTH [and non]. 6003, May 25 at 1247, noise jamming and presumably Echo of Hope on original frequency today, tho there`s a JBA carrier from something on 5995. Same jamming noise is on 6015 against KBS.

11680, May 25 at 1250, sweet music from paradise on earth, KCBS P`yongyang.

11710 & 11735 at 1252, different sweet music from VOK relay of KCBS, these two with bleeding jamming noise intermixed (Glenn Hauser, OK, DX LISTENING DIGEST)

** MADAGASCAR. 17640, May 24 at 1815, if still on the air, no signal from MWV APR in English. Had been reliable until this month. Perhaps in darker southern autumn it is no longer propagating at the first hop. Nor the repeat at 2000 which is even further into the darkside. Or just the pitiful low-solar activity MUFs we must endure (Glenn Hauser, OK, DX LISTENING DIGEST)

** OKLAHOMA [and non]. 1020, May 24 at 1849 UT, KOKP Perry is finally back on the air with sports talk; it was still missing earlier today at 1403 UT. KLEY 1130 KS is still off, and also circa 1315 UT May 25 (Glenn Hauser, OK, DX LISTENING DIGEST)

** TAIWAN. 11430-AM, May 25 at 1305, YL with series of 8 syllables each, in tonal Asian language; interrupted by regular speech, more 8-syllables. Presumably Star-Star as in May 23 EiBi, but not at this time, only 0400-0430, 0500-0530 & 0600-0630. Latest Aoki of May 25 does not show this time either for XingXing guangbo diantai 4, rather 0300-0330 & 0600-0630 with ``random numbers`` in H3E from 10 kW ND Kuanyin site. 

How do we know they are random? If so, it`s merely a distraxion, rather than encrypted spy messages, anything but random. Sounds like more than 10 kW to me; I was scanning the 11.4 MHz band for Indonesian QSO pirates, none heard. There was certainly a carrier but I did not check whether LSB was missing. Searching archive, 11430 was reported in 2016 as a Sound of Hope + jamming frequency. Now XingXing is in Aoki at 1200-1230 & 1300-1330 on 9725 instead, so maybe just moved to 11430 or in addition to 9725 (Glenn Hauser, OK, DX LISTENIND DIGEST) 

** U S A. WORLD OF RADIO 1878 monitoring: confirmed Wednesday May 24 at 2100 on WBCQ 7490 webcast. Also confirmed Wed May 24 at 2330 on WBCQ 9330v-CUSB, poor.

WORLD OF RADIO 1879 contents: Argentina non, Azerbaijan, Bougainville, Brasil, Canada and non, China, Iran non, Japan non, Korea South, Laos, México, New Zealand, Nigeria non, Papua New Guinea, Perú, Slovakia non, Tibet, USA

WORLD OF RADIO 1879 ready for first SW broadcasts May 25. Now with further attrition of WRMI airtimes, the début is 2330 Thu on WBCQ, and not on WRMI until Saturday night!

While I always give priority to SW airings, I remind everyone that WOR episodes are available ASAP from our website, five different podcast routes, several webcasting stations, notably early UT Thursdays on World FM in New Zealand. Full schedule with linx at:
Even our first SW broadcast is almost too late for some very perishable news, a special May 25 at 2300.

** U S A. 7490 // 5130, UT Thu May 25 at 0146, WBCQ with `Allan Weiner Worldwide` playback. Surprised to see current sked for this is a 3-hour block. Some other programs must be gone. ALL the AWWW entries:
Thu 00-03 7490, 01-03 5130; Sat 00-01 7490 & 5130 & 5130 (twice; but really runs way past 0100, sometimes almost to 0200 at least on 7490 in original live broadcast); Sat 23-24 on 9330. AWWW, sometimes very old ones, can show up anytime there is an hour to fill (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 9475 & 9930 & 12105, May 24 at 1820, all WTWW transmitters are missing. I should have checked 5085 & 5830 whether they were on night frequencies by negligence, which has happened before. Propagation is certainly OK, with neighbors WWCR very good on 9980 & 12160, fair on 13845 & 15825. Next check at 0147 UT May 25, 9475 is nominal, 12105 is missing, and 5085 is open carrier/dead air. It`s always something at this slipshod operation (Glenn Hauser, OK, DX LISTENING DIGEST)

#145 Issued on Thursday May 25, 2017 at 1400 UTC

We are now into the summer/winter solstice type of HF radio wave propagation conditions.

This means generally poor HF radio wave propagation conditions in the northern hemisphere especially at day and generally good HF radio wave propagation conditions in the southern hemisphere especially at day.

Globally HF radio wave propagation conditions are most evenly balanced
during the fall and spring equinoxes and most diametrically opposed during
the summer and winter 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).

This HF Radio wave propagation forecast is based on the W4HM_Cap HF radio wave propagation prediction software.

The hamateur radio JT65A mode RF signal levels received are based on 5 watts and ½ wave dipole up at 40 feet.

The hamateur radio PSK31 mode RF signal levels received are based on 25 watts and ½ wave dipole up at 40 feet.

The hamateur radio CW mode RF signal levels received are based on 50 watts and ½ wave dipole up at 40 feet.

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

The HF shortwave broadcast band AM Mode RF signal levels are based on 100,000 watts (100 kw) and a typical VOA type curtain array antenna.

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

Please keep in mind that this is a relatively simplified HF radio wave
propagation forecast, so as to keep it easily understandable and applicable by the average radio enthusiast.

Globally HF radio wave propagation conditions are most evenly balanced
during the fall and spring equinoxes and most diametrically opposed during
the summer and winter solstices.

Conditions change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the
ecliptic, as well as by radio wave frequency. This is due to changes in the
maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2).

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

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

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

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

Solar, Space & Geomagnetic Weather Conditions On

Wednesday May 24, 2017-

Solar activity was low.

Earth's geomagnetic field was at a quiet level.

The three daily solar flux index (SFI) numbers were 77.7 77.9 78.3.

The official daily sunspot number (SSN) was 15.

In 2017 officially there were 37 days with a daily sunspot number (SSN) of
0.

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

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

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

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

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

There were 2 newly risen or emerged official sunspot groups.

Sunspot group #12659 was located near N13W18 with a magnetically simple beta magnetic signature.

Sunspot group #12660 was located near S09W40 with a magnetically simple beta magnetic signature.

There were 2 unofficial and as of yet unnumbered earth facing sunspot groups located near

S07W07,
N15W68.

No earth facing C class or larger solar flares occurred.

No day side high latitude solar fade outs (SFO) occurred.

The solar fade out (SFO) events are related to polar cap absorption (PCA) occurrences mostly caused by energetic protons striking earth’s geomagnetic field and increasing RF signal absorption in the D layer at high latitudes.

No earth facing coronal mass ejections (CME) occurred.

No earth facing collapsing magnetic filament eruptions occurred.

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

1 1 1 1 1 1 0 0.

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

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

5 and 2,

which was at quiet geomagnetic conditions.

The Ap geomagnetic indices are-
0-7- quiet
8-15 unsettled
16-29- active
30-49- minor geomagnetic storm
50-99- major
100-400- severe
>401- our atmosphere just got cooked off like on Mars and we are all dead.
The 24 hour period averaged energetic proton flux was at a background level below 10 MeV.

The 24 hour period averaged background x-ray flux was at B3.81.

The 24 hour period averaged vertical component (Bz) of earth's geomagnetic magnetic field was at

-0.50 nT south.

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

 -12 and +4 nT.

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

483 and 352 km/s.
 
There was a new earth facing northern hemisphere coronal hole #805. It became directly earth facing (geoeffective) on Tuesday May 23, 2017. However as it’s located at a high latitude position on the earth facing side of the sun and beginning to dissipate, it probably won’t impact earth’s geomagnetic field in a negative way.

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

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

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

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

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

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

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

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

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

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

8.) No current STRATWARM alert.

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

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

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

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

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

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

Glenn Hauser logs May 23-24, 2017


** ARGENTINA [non]. Further chex for expanded RAE relays on WRMI, May 23-24:

11580, May 23 at 2119, now RAE German has replaced R. Slovakia in English during this hour, including some tango.

11580, May 23 at 2225, this hour is still in Spanish // 5950, not Italian. RAE did upload an Italian hour to WRMI as early as May 22 along with all the other languages. (One has to be careful monitoring, as the Argentine accent in Spanish is Italian-influenced, and Italian service might include clips in real Spanish.)

7730, May 24 at 0015, still `Jazz from the Left` on WRMI, instead of RAE in Spanish, so perhaps other variety programs during this hour will also continue for a while longer.

11580, May 24 at 0146, PCJ Radio International is still running during this hour on UT Wednesday, as an additional frequency for the RAE English hour has not been implemented; remains on 9395 only.

7730, May 24 at 0610, Japanese RAE again, but 5850 is now in BS // 5890 WWCR not synched. 5850 had been running World Music mostly during this hour. The WRMI grid shows the 06-07 Japanese and 07-08 English on BOTH frequencies. With 08-09 Chinese and 09-10 Japanese on 5850 only. Really, 15-16 JST in the summer is too early to expect much propagation to Japan on 5850; and even 7730 may not be making it much that soon.

11580, May 24 at 1316 and 1351 chex, during RAE French hour as heard yesterday, off the air! Or JBA carrier possibly exciter from WRMI, as 11825 WRMIBS is S9. Or Sound of Hope 0.1 kW in Taiwan as in Aoki and/or provoking ChiComjam (Glenn Hauser, OK, DX LISTENING DIGEST)

** IRAN. 15520, May 24 at 1400, JBA carrier; could Spain be there on Wednesday? Aoki shows VIRI in Urdu until 1420 daily, so that overlaps with Spain on weekends (Glenn Hauser, OK, DX LISTENING DIGEST)

** OKLAHOMA. 1020, May 24 at 1403 UT check, KOKP Perry is still off the air, as it has been since at least May 20. Is there any explanation at
Of course not! But soon to be redubbed Double Play Sports Radio (Glenn Hauser, Enid, DX LISTENING DIGEST)

#144 Issued on Wednesday May 24, 2017 at 1230 UTC

We are now moving into the summer/winter solstice type of HF radio wave propagation conditions.

This means generally poor HF radio wave propagation conditions in the northern hemisphere especially at day and generally good HF radio wave propagation conditions in the southern hemisphere especially at day.

Globally HF radio wave propagation conditions are most evenly balanced
during the fall and spring equinoxes and most diametrically opposed during
the summer and winter 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).

This HF Radio wave propagation forecast is based on the W4HM_Cap HF radio wave propagation prediction software.

The hamateur radio JT65A mode RF signal levels received are based on 5 watts and ½ wave dipole up at 40 feet.

The hamateur radio PSK31 mode RF signal levels received are based on 25 watts and ½ wave dipole up at 40 feet.

The hamateur radio CW mode RF signal levels received are based on 50 watts and ½ wave dipole up at 40 feet.

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

The HF shortwave broadcast band AM Mode RF signal levels are based on 100,000 watts (100 kw) and a typical VOA type curtain array antenna.

Please keep in mind that this is a relatively simplified HF radio wave
propagation forecast, so as to keep it easily understandable and applicable by the average radio enthusiast.

Globally HF radio wave propagation conditions are most evenly balanced
during the fall and spring equinoxes and most diametrically opposed during
the summer and winter solstices.

Conditions change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the

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 May 23, 2017-

Solar activity was low.

Earth's geomagnetic field was at an unsettled level.

The three daily solar flux index (SFI) numbers were 75.4 76.0 75.4.

The official daily sunspot number (SSN) was 47.

In 2017 officially there were 37 days with a daily sunspot number (SSN) of
0.

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

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

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

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

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

There were 4 newly risen or emerged official sunspot groups.

Sunspot group #12656 was located near N12W47 with a magnetically simple alpha magnetic signature.

Sunspot group #12658 was located near S06W34 with a magnetically simple alpha magnetic signature.

Sunspot group #12659 was located near N13W05 with a magnetically simple beta magnetic signature.

Sunspot group #12660 was located near S10W25 with a magnetically simple beta magnetic signature.

There were 3 unofficial and as of yet unnumbered earth facing sunspot group located near

S09E09,
N15W56,
S32W09.

No earth facing C class or larger solar flares occurred.

No day side high latitude solar fade outs (SFO) occurred.

The solar fade outs (SFO) are also called polar cap absorption (PCA) mostly caused by energetic protons striking earth’s geomagnetic field and increasing RF signal absorption in the D layer at high latitudes.

An earth facing and partially directed (geoeffective) coronal mass ejection (CME) occurred. It may impact earth’s geomagnetic field in a negative manner on approximately Friday May 26, 2017.

No earth directed collapsing magnetic filament eruptions occurred.

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

1 3 1 1 2 1 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 4,

which was at unsettled to quiet geomagnetic conditions.

The Ap geomagnetic indices are-
0-7- quiet
8-15 unsettled
16-29- active
30-49- minor geomagnetic storm
50-99- major
100-400- severe
>401- our atmosphere just got cooked off like on Mars and we are all dead.
The 24 hour period averaged energetic proton flux was at a background level below 10 MeV.

The 24 hour period averaged background x-ray flux was at B4.45.

The 24 hour period averaged vertical component (Bz) of earth's geomagnetic magnetic field was at

-2.30 nT south.

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

 -18 and -2 nT.

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

557 and 449 km/s

and was directly connected by a high speed solar wind stream (HSS) to trans equatorial coronal hole (CH) #804 (#802).

There was a new earth facing northern hemisphere coronal hole #805. It became directly earth facing (geoeffective) on Tuesday May 23, 2017. However as it’s located at a high latitude position on the earth facing side of the sun, it probably won’t impact earth’s geomagnetic field in a negative way.

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

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

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

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

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

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

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

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

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

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

8.) No current STRATWARM alert.

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

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

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

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

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

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

Glenn Hauser logs May 22-23, 2017


** ARGENTINA [non]. The expanded relays of RAE ATTW via WRMI did not start Monday May 22, but they did start Tuesday May 23.

11580, May 22 at 2025, RAE multilingual ID loop --- but it`s merely a clip within the Russian-language DX program `Padio Pinorama` which is now scheduled Mondays at 2000. The 20-21 block remains with variety of programming. 

11580, May 22 at 2100, R. Slovakia International English is still here, for the last time (except will continue on weekends only). Intro mentions the current date May 22, which is something all relayed stations should do. This is to be replaced by RAE in German for the full hour.

11580, May 22 at 2200, RAE relay in Spanish, about Argentina with Argentine accent, as has already started a few weeks ago, presumably // 5950 --- yes, by 2247, 5950 is very poorly audible. New sked will split off 11580 for Italian instead.

7730, May 23 at 0030, WORLD OF RADIO is still airing instead of RAE in Spanish

9395, May 23 at 0100, the RAE English hour unrechecked tonight, and presumably still not duplicated on 11580 as originally planned. 

5850 // 7730, May 23 at 0626, tango, and Japanese announcement, so the expanded RAE relay sked has now started: 06-07 Tue-Sat in Japanese; later hours not checked, but scheduled to be: 07-08 English on both; 08-09 Chinese & 09-10 Japanese on 5850 only. Adrián Korol tells me that the Japanese staff happen to be on vacation, so initially that service will play evergreen shows with no news. RAE has already had good response from Japan.

9955, May 23 at 1100, RAE poor in Portuguese, and also // slightly better 9455, which was not publicized, but maintaining the // hour as previously scheduled with variety of programming, ex WOR at 1100 Tuesdays. 

11580, May 23 at 1300, RAE in French, fair, replacing WORLD OF RADIO on Tuesdays; recheck 1344, after Spanish song, more French about le football. RAE`s French program is only half an hour, so apparently running it twice (perhaps playing previous and current day`s show would seem less repetitive during a single consecutive hour?)

The transmission schedule at http://tinyurl.com/WRMIfqs has not been updated, but the programming grid below it has been, to show most of the RAE languages, not including 00-01 UT on 7730 which still has the old sked instead of expected RAE Spanish. The separate 9955 sked has also changed 1100 Mon-Fri to RAE in Portuguese (Glenn Hauser, OK, DX LISTENING DIGEST)

** KOREA SOUTH [and non]. 5995, May 23 at 1258, JBA carrier, and nothing, not even jamming on 6003, so Echo of Hope has apparently returned to new 5995, after a brief resumption of old 6003. And another carrier on new 6350 instead of old 6348. RNZI remains safely on 6170, with bell-bird IS from 1258.

Chris Krug in Tulsa also reports this to the DXLD yg: ``Echo of Hope back on 5995 at 1045 UT (May 23) with nice copy (23322), 6003 still being jammed. Announcers talking and laughing. RHC crowds it a little at 1100 but still armchair copy. Chris KC5IIE, Tulsa, OK, SDRplay - 40m loop`` (Glenn Hauser, Enid OK, DX LISTENING DIGEST)

** NIGERIA. 7254.942, May 23 at 0548, VON is already on, S9+20 with rappish Afromusic, dead air, and resumes. Warming up for the 0600 Hausa, presumably preceded by a few minutes of official drumming IS (Glenn Hauser, OK, DX LISTENING DIGEST)

** PERU. 5980, May 22 at 2333, no signal from R. Chaski, despite not cutting off until 2335:22* at previous catch May 20. Therefore it`s just off, or has already reset the autotimer closer to 2330.0. Further chex required (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. WORLD OF RADIO 1878 monitoring: confirmed Monday May 22 at 2330 on WBCQ 9330.30v-CUSB, fair S7-S9. Also confirmed UT Tuesday May 23 at 0030 on WRMI 7730, S9+20, which is expected to be replaced by Spanish hour from RAE, maybe from May 24? NOT confirmed Tue May 23 at 1100 on WRMI 9455 & 9955, which has now been replaced by RAE in Portuguese; nor Tue May 23 at 1300 on WRMI 11580, now replaced by RAE in French. Next WORs, including those still showing on WRMI sked:
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 1315.5 WRMI 9955 to SSE
Wed 2100   WBCQ 7490v to WSW

Solar, Space & Geomagnetic Weather Conditions On



Monday May 22, 2017-



Solar activity was moderate.



Earth's geomagnetic field was at an unsettled level.



The three daily solar flux index (SFI) numbers were 74.1 74.4 74.7.



The official daily sunspot number (SSN) was 55.



In 2017 officially there were 37 days with a daily sunspot number (SSN) of

An earth facing but probably not directed (geoeffective) coronal mass ejection (CME) occurred.



A partial HALO CME is visible off the West limb during a data gap in

coronagraph imagery. As it currently stands, the images stop at 23/0236

UTC, then resume at 23/0824 UTC with a CME well underway. An area of

dimming is visible in AIA/193 imagery starting near 23/0326 UTC. Further

analysis will need to be conducted once the coronagraph imagery updates

to determine if the two events are connected, and also to determine if

the ejecta has an Earth-directed component.

No earth directed collapsing magnetic filament eruptions occurred.



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

and was directly connected by a high speed solar wind stream (HSS) to trans equatorial coronal hole (CH) #804 (#802).

There was a new earth facing northern hemisphere coronal hole #805. It will become directly earth facing (geoeffective) on Tuesday May 23, 2017.

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.
