Glenn Hauser logs September 17-18, 2017

** AUSTRALIA. 9690, Sept 18 at 1230, RBA Burmese service is still here instead of listed and announced 9685 where there is nothing; gospel music, poor (Glenn Hauser, OK, DX LISTENING DIGEST)

** CUBA. 6100, Sept 18 at 0607, RHC English reactivated here after missing several nights, good S9+20, but now 6060 is missing. Still // 6000 undermodulated; 6145 S9+30 but undermod; and 5040 off as it normally is by 0600.

5025, Sept 18 at 0611, R. Rebelde with JBM music (Glenn Hauser, OK, DX LISTENING DIGEST)

** INDONESIA. 3325, Sept 18 at 1228 immediately upon tune-in, ``Radio Republik Indonesia`` ID in passing, at S2-S4, with Bougainville no doubt already off --- the last living Indonesian SW station as 9525-, VOI is still absent (but maybe not forever) (Glenn Hauser, OK, DX LISTENING DIGEST)

** MEXICO. 560, Sept 18 at 1200 mentions Monterrey, Nuevo León, but then spoken and sung ``La Tremenda``, which is XESRD, Santiago Papasquiaro, Durango, 10/1 kW (Glenn Hauser, OK, DX LISTENING DIGEST)

** MEXICO. 630, Sept 18 at 1202, full ID for XEFB, Monterrey NL, by SHVA (super-hype voice actor) (Glenn Hauser, OK, DX LISTENING DIGEST)

** MEXICO. 790, Sept 18 at 1205, patriotic speech clips, probably from Sept. 16 celebrations; 1207 surprised by untranslated English clips of Tillerson, Haley, May; back to Spanish, loops SW and dominant. 1212 program ID as `En los Tiempos de la Radio``; Senado PSA; and finally ID as ``790 AM Grupo Fórmula La Paz``; 1213 mini-features `México y sus Sabores` about quesadillas; `Rincones de México` about Cuatro Ciénagas, Coahuila and its dunes; then another `Sabores` about gorditas. This is XENT, 10000/750 watts, La Paz BCS. Always neat to hear a station from the far end of Mexico; already this morning had unlogged closer but nearby Sinaloans across the Cortez Sea on 610, 650 (Glenn Hauser, OK, DX LISTENING DIGEST)

** NEW ZEALAND. 6679-USB, Sept 18 at 1251, VOLMET in monotone DU accent, can`t catch locations until 1253 ``Terminal forecast, Auckland``; S5. Per EiBi it is indeed Auckland, starting at :20 and :50 past the hours, time-shared with Tokyo, Hong Kong, Honolulu (Glenn Hauser, OK, DX LISTENING DIGEST)

** OKLAHOMA. RF 42, Sept 18 at 1448 UT, barely enough morning tropo to visiblize sporadically KBZC-LD OKC. Keeps changing its lineup of subchannels. Now 42-2 is Tuff TV, with ``creating conservative political talk show``, `Live from Studio 6B`, set up like a radio studio. Program website and Tuff TV +program sked websites won`t finish loading. Finally! A conservative talkshow!

42-1 has a sillyballgame which Rabbitears.info now labels as Stadium; 42-3 still Buzzr; 42-4 GetTV; 42-5 QVC; 42-6 QVC-2; and I didn`t get up to 42-7 to reconfirm Shop LC. NTSC KOCY-LP OKC also barely visible snowy on ch 48 (Glenn Hauser, Enid, DX LISTENING DIGEST)

** U S A. 7245-LSB, Sept 18 at 1239, Navy Club Net with KK6BS (``Battle-Ship``) in Gainesville FL about getting back to normal. Joseph C. Folsom (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. WORLD OF RADIO 1895 monitoring: confirmed Sunday September 17 at 2346 the 2330 on WBCQ, 9329.95v-CUSB, fair. Also confirmed UT Monday September 18 at 0304 on WBCQ, 5130.240-AM, VP in noise level (and 3250 not on // like it was during AWWW UT Sat). Also confirmed after 0330 on WRMI webcast, and presumably 9555. Next:
Mon 2330   WBCQ 9330v-CUSB to WSW
Tue 0030   WRMI 7730 to WNW [but still not restored as of Sept 18]
(Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 7780, Sept 18 at 1235, this WRMI is off again, while 7570 is VG with BS. Also still on are 5850, 9395, 9455, 9955, 11580.

5950, Sept 18 at 1248 BS on this WRMI at S6; new on this transmitter?

WRMI skedgrid has now been updated as of Sept 17:
http://www.tinyurl.com/WRMIfqs

It shows 5950 from two different transmitters, at the same time:
1100-1230, #3 at 160 degrees, and #14 at 181 degrees; #14 also at 22-01. But not after 1230. 

5850 has an addition at 2230-2300 `Yeshua` before Radio Tirana. 

11825 is still missing at 1407 Sept 18, but 7780 is now on with `The Power Hour` ads // 9395, 9455.

``WRMI Radio Miami International 17 hrs ·
Many thanks to Ray Robinson of KVOH in Los Angeles for guest-hosting Wavescan this week! Jeff White has been busy with the hurricane reparations at WRMI. There will be a report on WRMI's hurricane experiences on this week's Wavescan, which begins airing today, September 17th.

2125 UTC Sunday September 17, 2017 - The frequency of 5950 kHz is now back on the air! This broadcasts Family Radio, Adventist World Radio and several other programs on a beam to Cuba and the Caribbean. We are using Transmitter 3 instead of Transmitter 14, since Transmitter 14's transmission lines are still not repaired.

Para nuestros oyentes en Cuba y el Caribe, ya está en el aire la frecuencia de 5950 kHz!

WRMI Radio Miami International
1615 UTC Sunday September 17 - It's been almost a week since Hurricane Irma arrived here at Okeechobee. We now have 10 of our 14 transmitters on the air again with their normal power:

Transmitter  1 at  7780 kHz
Transmitter  2 at  5985 kHz
Transmitter  4 at  9955 kHz
Transmitter  5 at  9455 kHz
Transmitter  6 at  9395 kHz
Transmitter  7 at 21525 kHz
Transmitter  9 at 11580 kHz
Transmitter 10 at 11530 kHz
Transmitter 11 at  7570 kHz
Transmitter 12 at  5850 kHz

We will continue working to put the others on the air during the next few days. We cannot put Transmitter 3 on 15770 kHz again on the same antenna because the hurricane destroyed the 44-degree European antenna that this transmitter was using. But we may use Transmitter 3 with another antenna in the near future.

It seems that our Internet service has finally come back, so we are hoping that Monday we can have our audio livestream working normally again, and that our customers can again send us their programs via Internet.

Thanks to our Facility Manager Pat Travers and his team for their hard work over the last week repairing all of the transmission lines in the antenna field, we have been able to return to the air on so many transmitters so fast.

And thanks to our listeners for their patience waiting for us. The hurricane has been a bad experience, but we have overcome it and we are in the air again to serve you

WRMI Radio Miami International
1615 UTC Domingo Septiembre 17 - Ha sido casi una semana desde que llegó el Huracán Irma aquí a Okeechobee. Ahora tenemos 10 de nuestros 14 transmisores en el aire de nuevo con su potencia normal:

Transmisor  1 en  7780 kHz
Transmisor  2 en  5985 kHz
Transmisor  4 en  9955 kHz
Transmisor  5 en  9455 kHz
Transmisor  6 en  9395 kHz
Transmisor  7 en 21525 kHz
Transmisor  9 en 11580 kHz
Transmisor 10 en 11530 kHz
Transmisor 11 en  7570 kHz
Transmisor 12 en  5850 kHz

Seguiremos trabajando para poner los otros en el aire durante los próximos días. No podemos reponer Transmisor 3 en 15770 kHz en la misma antena porque el huracán destruyó la antena de 44 grados hacia Europa que este transmisor estaba usando. Pero quizás usaremos Transmisor 3 con otra antena en el futuro cercano.

Parece que nuestro servicio de Internet ha regresado por fin, así estamos esperando que mañana lunes podemos tener nuestro stream de audio en vivo funcionando normalmente de nuevo, y que nuestros clientes puedan mandarnos sus programas por Internet de nuevo.

Gracias a nuestro Gerente de Facilidad Pat Travers y su equipo por su trabajo duro durante la semana pasada reparando todas las líneas de transmisión en el campo de antenas, hemos podido regresar al aire en tantos transmisores tan rápido.

Y gracias a nuestros oyentes por su paciencia esperándonos. El huracán ha sido una experiencia mala, pero la hemos superado y ya estamos en el aire de nuevo para servirles.`` (Glenn Hauser, OK, DX LISTENING DIGEST)

UNIDENTIFIED. Trans-Pacific JBA MW carrier search, 1154 UT September 18: only 702, with two carriers beating from WSW: presumably 50 kW 2BL ABC Sydney, and 10 kW Magic, Auckland NZ, as other monitors have been getting into deep North America (tho there is another 1 kW NZer). Skipped midband, but nothing detected on hiband either (Glenn Hauser, OK, DX LISTENING DIGEST)

Highlights of Solar and Geomagnetic Activity 11 - 17 September 2017

Solar activity was at predominately very low levels through the
summary period, interupted by a brief period of low activity on 12
Sep as Region 2680 (N09, L=317, class/area Hsx/140 on 12 Sep)
produced a pair of impulsive C-class flares. 11 Sep saw the X-ray
background elevated at the C-level due to slow decay from the X8
flare (R3-Strong) observed at 10/1606 UTC. No Earth-directed CMEs
were detected during the period.

Of note, two halo CMEs were observed on 17 Sep. The first one, a
full-halo CME, was first observed in LASCO C2 imagery at 17/1224
UTC, while the second one was a partial-halo CME, first observed in
LASCO C2 imagery at 17/1424 UTC. The source region of both CMEs was
determined to be from old active Region 2673 (S09, L=119) which is
presently on the back side of the solar disk. Old Region 2673 is due
to return on 23 Sep.

10 MeV and 100 MeV protons at geosynchronous orbit exceeded their
respective event thresholds during the period, both in response to
the X8 flare observed on 10 Sep. At 10/1645 UTC, 10 MeV protons
exceeded 10 pfu (S1-Minor), reached a maximum of 1,490 pfu
(S3-Strong) and decayed below the S1 level at 14/1725 UTC. The 100
MeV proton flux exceeded the 1 pfu level at 10/1625 UTC, reached a
maximum of 68 pfu at 10/2215 UTC and ended at 13/0335 UTC.

The greater than 2 MeV electron flux at geosynchronous orbit was at
moderate levels on 13-14 Sep and high levels on 11-12 and 15-17 Sep.
A maximum of 46,263 pfu was observed at 17/1610 UTC.

Geomagnetic field activity was a quiet to minor storm levels
(G1-Minor) and major storm levels (G2-Moderate) during the summary
period. Quiet to unsettled levels were observed on 11 Sep through
late on 12 Sep due to waning effects from a negative polarity CH
HSS. Late on 12 Sep through midday on 13 Sep, field activity
increased to active to minor storm levels (G1-Minor) in response to
CME effects from the 10 Sep X8 flare. During this timeframe, total
field peaked at 16 nT, the Bz component reached a maximum southward
extent of -12 nT and solar wind speed peaked at about 650 km/s.
Quiet levels were observed for the remainder of 13 Sep through
midday on 14 Sep.

From midday on 14 Sep through 17 Sep, field activity was dominated
by effects from a recurrent, positive polarity CH HSS. Unsettled to
G1-Minor and G2-Moderate levels were observed through 16 Sep with
quiet to active levels present on 17 Sep. During this timeframe,
total field peaked at near 22 nT, the Bz component reached a maximum
southward extent of -18 nT and solar wind speed peaked at about 775
km/s.

FORECAST OF SOLAR AND GEOMAGNETIC ACTIVITY 18 SEPT-14 OCT 2017

Solar activity is expected to be at predominately very low levels on
18-22 Sep and 08-14 Oct. R1-R2 (Minor-Moderate) levels are expected
on 23 Sep-07 Oct due to the return of old Region 2673 (S09, L=119).

The greater than 10 MeV protons at geosynchronous orbit are expected
to remain at background levels from 18-22 Sep and 08-14 Oct. A
chance for an S1-S2 (Minor-Moderate) proton event is possible from
23 Sep-07 Oct in association with significant flare activity after
the return of old Region 2673.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at high levels on 18-22 Sep, 28 Sep-19 Oct and 12-14
Oct due to CH HSS influence. Normal to moderate levels are expected
for the remainder of the outlook period.

Geomagnetic field activity is expected to be at unsettled to active
levels on 18-20 Sep, 24-25 Sep and 30 Sep-02 Oct with G1 (Minor)
storm conditions possible on 27-29 Sep and 11-14 Oct due to
recurrent CH HSS activity. Mostly quiet conditions are expected for
the remainder of the outlook period.

Published on Monday September 18, 2017 at 1530 UTC
Solar Space & Geomagnetic Weather Conditions On Sunday September 17, 2017-
Solar activity had been very low.
Earth's geomagnetic field had been at a minor geomagnetic storming level.
The three daily solar flux index (SFI) numbers had been 70.5 72.2 72.3.
The official daily sunspot number (SSN) had been 13.
In 2017 officially there were 56 days with a daily sunspot number (SSN) of 0. Considering that solar minimum won't occur for approximately 2 more years, +/- 1 year, daily SSN's of 0 are occurring unusually early.
In 2016 officially there were 32 days with a daily sunspot number (SSN) of 0.
As we move forward towards the next solar minimum between solar cycle #24 and #25 the number of days with a 0 daily SSN will steadily increase. Eventually every day for many, many, many months will see a 0, the big goose egg.
In 2008 I forecasted solar cycle 24 to be the weakest in the past 100 years and that forecast verified. I also forecasted that solar cycle 25 would be virtually nonexistent, similar to the Dalton type solar minimum that occurred in the early 1800's.
Other than sunspot magnetic polarity it will probably be very difficult to determine when solar cycle 24 ended and solar cycle 25 began.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Officially there had been 1 earth facing sun spot group (SSG).
Sunspot group (SSG) #12680 was located near N08W25 with a simple alpha magnetic signature. It was capable of producing a small in size C class solar flare.
There had been 3 unofficial and as of yet unnumbered earth facing sunspot groups (SSG) near
N16W04,
S11E33,
N05E67.
There had been no small in size C class solar flare or larger.
There had been no directly earth aimed (geoeffective) coronal mass ejection (CME).
There had been no partially earth aimed coronal mass ejection (CME).
There had been no directly or partially earth aimed (geoeffective) coronal mass ejection (CME) related high latitude energetic proton storm >10 MeV (10+0).
The high latitude absorption via earths over ionized D layer is called polar cap absorption. The mid latitude absorption is caused by energetic electrons and protons spiraling down earth’s magnetic field lines into the equatorial ring current.
There had been no earth aimed (geoeffective) solar flare related x-ray day side solar fade out (SFO).
There had been no directly earth aimed (geoeffective) collapsing magnetic filament eruption.
The 24 hour period 3 hour interval planetary K index (Kp) had been at active to quiet geomagnetic conditions of
3 3 2 2 4 4 2 2.
The 24 hour period 3 hour interval Boulder, CO K index had been at active to quiet geomagnetic conditions of
4 4 3 3 4 3 2 2.
The K(p) geomagnetic indices are-
0-2- quiet                                                                                                                                                                                                3- unsettled                                                                                                                                                                                                                 4- active                                                                                                                                                                                                 5- minor geomagnetic storming                                                                                                                                                                     6- moderate                                                                                                                                                                                                           7- strong                                                                                                                                                                                                                   8- severe                                                                                                                                                                                                                9- extreme                                                                                                                                                                                            10- our atmosphere just got cooked off like on Mars and we are all dead.
The 24 hour period maximum and minimum planetary A index (Ap) had ranged between
27 and 6,

Global Daily HF Radio Wave Propagation Forecast-

We are now entering the fall/spring equinox type of HF radio wave propagation conditions. Globally HF radio wave propagation conditions are most evenly balanced across the equator during the fall and spring equinox.

HF radio wave propagation conditions change hourly, 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).

HF radio wave propagation conditions trend- deteriorating.

Northern Hemisphere Radio Wave Propagation Forecast-

80-60 (75-60) meters- fair at night and poor at day,
40-30 (41-25) meters- fair at night and fair at day,
20-17 (22-16) meters- very poor at night and fair at day,
15 (13) meters- very poor at night and poor at day,
12-10 (11) meters- very poor at night and very poor at day.

During the northern hemisphere winter season the higher HF bands of 10-20 meters (11-19 meters) close sooner due to less sun light illuminating the ionosphere than in the northern hemisphere. But the maximum useable frequency (MUF) is higher than in the northern hemisphere as the F layer of the ionosphere is lower in height and is more dense.

Southern Hemisphere Radio Wave Propagation Forecast-

80-60 (75-60) meters- fair at night and poor at day,
40-30 (41-25) meters- fair at night and fair at day,
20-17 (22-16) meters- very poor at night and fair at day,
15 (13) meters- very poor at night and poor at day,
12-10 (11) meters- very poor at night and very poor at day.

Keep in mind that almost daily during the southern hemisphere summer season you will find that the 10 (11) meter bands will open via short north-south and east-west propagation paths via sporadic E (Es). Also when multiple sporadic E (Es) clouds form and line up favorably much longer propagation paths open up on east-west paths. And last but not least north-south propagation paths occur across the equator via trans equatorial propagation (TEP).

Received RF signal strength scale-
Very Good- +1 over S9 Or Greater
Good- S7-9
Fair- S4-6
Poor- S1-3
Very Poor- S0

This HF Radio wave propagation forecast is produced based on the SIGINT_CAP HF radio wave propagation prediction software. I wrote it beginning in the late 1980’s but I’m sorry to say that it can’t be distributed to the general public.

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

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

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

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

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

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

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


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

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

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

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

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

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

Published on Sunday September 17, 2017 at 1600 UTC
Solar, Space & Geomagnetic Weather Conditions on Saturday September 16, 2017-
Solar activity had been very low.
Earth's geomagnetic field had been at an active geomagnetic condition level.
The three daily solar flux index (SFI) numbers had been 70.5 72.1 71.6.
The official daily sunspot number (SSN) had been 13.
In 2017 officially there were 56 days with a daily sunspot number (SSN) of 0. Considering that solar minimum won't occur for approximately 2 more years, +/- 1 year, daily SSN's of 0 are occurring unusually early.
In 2016 officially there were 32 days with a daily sunspot number (SSN) of 0.
As we move forward towards the next solar minimum between solar cycle #24 and #25 the number of days with a 0 daily SSN will steadily increase. Eventually every day for many, many, many months will see a 0, the big goose egg.
In 2008 I forecasted solar cycle 24 to be the weakest in the past 100 years and that forecast verified. I also forecasted that solar cycle 25 would be virtually nonexistent, similar to the Dalton type solar minimum that occurred in the early 1800's.
Other than sunspot magnetic polarity it will probably be very difficult to determine when solar cycle 24 ended and solar cycle 25 began.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Officially there had been 1 earth facing sun spot group (SSG).
Sunspot group (SSG) #12680 was located near N08W12 with a simple alpha magnetic signature. It was capable of producing a small in size C class solar flare.
There had been 1 unofficial and as of yet unnumbered earth facing sunspot group (SSG) near
N16E11.
There had been no small in size C class solar flare or larger.
There had been no directly earth aimed (geoeffective) coronal mass ejection (CME).
There had been no partially earth aimed coronal mass ejection (CME).
There had been no directly or partially earth aimed (geoeffective) coronal mass ejection (CME) related high latitude energetic proton storm >10 MeV (10+0).
The high latitude absorption via earths over ionized D layer is called polar cap absorption. The mid latitude absorption is caused by energetic electrons and protons spiraling down earth’s magnetic field lines into the equatorial ring current.
There had been no earth aimed (geoeffective) solar flare related x-ray day side solar fade out (SFO).
There had been no directly earth aimed (geoeffective) collapsing magnetic filament eruption.
The 24 hour period 3 hour interval planetary K index (Kp) had been at minor geomagnetic storming to unsettled geomagnetic conditions of
5 5 3 4 4 4 3 3.
The 24 hour period 3 hour interval Boulder, CO K index had been at minor geomagnetic storming to quiet geomagnetic conditions of

The 24 hour period maximum and minimum planetary A index (Ap) had ranged between
56 and 12,
which was at major geomagnetic storming to unsettled geomagnetic conditions.
The Ap geomagnetic indices are-

The 24 hour period maximum background x-ray flux had been at B1.03.
The 24 hour period maximum southward swing of the vertical component (Bz) of earth's geomagnetic magnetic field had been at approximately

-6 nT.

The larger the negative value the further south-north that visible aurora can possibly be observed outside of the polar regions.

The 24 hour period maximum and minimum disturbance storm time index (Dst) had ranged between
-39 and -12 nT.
The 24 hour period maximum and minimum solar wind speed ranged had ranged between
753 and 568 km/s.
The solar wind speed had been under the influence of the below mentioned coronal hole (CH).
There was 1 recurrent medium in size earth facing northern hemisphere coronal hole (CH) #824 (#820).
Its associated high speed solar (HSS) wind stream had been attached to earths geomagnetic field and impacting earths ionosphere in a negative manor in the form of active (Kp-4) geomagnetic conditions.
There was 1 newly risen small in size earth facing southern hemisphere coronal hole (CH) #825.

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.
