BBC World Service launches £289 million expansion with services in new languages

The BBC World Service will extend its reach across the world as it launches new services in 12 languages such as Amharic, Afaan Oromo and Tigrinya from next month.
The service aims to target areas such as Ethiopia and Eritrea as part of the £289 million expansion, its biggest since the 1940s.
The expansion will continue to roll out further services, including Korean, throughout the year with a view to deliver BBC News in more than 40 languages.
Plans begin on Monday with the launch of a new digital service in Pidgin, a language spoken by more than 75 million people across Nigeria, Cameroon, Ghana and Equatorial Guinea.
Describing the wider project as a “new chapter” for the BBC, the broadcaster’s director general, Lord Tony Hall, said: “The BBC World Service is one of the UK’s most important cultural exports.
“In a world of anxieties about ‘fake news’, where media freedom is being curtailed rather than expanded, the role of an independent, impartial news provider is more important than ever.
“The new services we’re launching will reach some of the most under-served audiences in the world.”
Commenting on the new Pidgin service, which will feature six daily editions of BBC Minute, World Service director Francesca Unsworth said: “For more than 80 years the BBC World Service has brought trusted news to people across the globe.
“I’m delighted that millions in West and then East Africa will be able to access the BBC in the languages they speak.”
She added: “The BBC World Service expansion will also bring benefits to audiences in the UK. Having more journalists on the ground will enrich our international reporting, bringing news from areas which are often under-reported.”
The Pidgin service will grow in November to include two daily news video bulletins and will be followed by two further West Africa services, in Yoruba and Igbo, next year.
The upcoming services in Amharic, Afaan Oromo and Tigrinya will be supplemented later in the year with shortwave radio services made up of 15-minute current affairs programmes followed by five-minute Learning English programmes on weekdays. (bt.com)

Highlights of Solar and Geomagnetic Activity 14 - 20 August 2017

Solar activity ranged from very low levels to moderate levels over
the period. Very low levels were observed on 16-17 Aug, low levels
were observed on 14-15 Aug and again from 18-19 Aug, while moderate
levels were observed on 20 Aug.

The period began with Region 2671 (N11, L=305, class/area Fkc/410 on
18 Aug) rotating around the east limb. The region was in a growth
phase through 18 Aug and rapidly developed from a simple Hax/alpha
spot group to an Fkc/beta-gamma group by 17 Aug with an extent
reaching 20 heliographic degrees by 20 Aug. Although a magnetically
complex spot group, it only managed 11 C-class flares. The largest
was a C7/Sf, with an associated Type II (928 km/s) radio sweep, at
19/2155 UTC. Although coronal dimming was observed in SDO/AIA 193
imagery beginning at 19/2143 UTC, there was no observable
indications of an associated coronal mass ejection (CME) in
coronagraph imagery. Another region began producing C-class activity
on the east limb beginning on 18 Aug. By 20 Aug, the region rotated
into view and was numbered 2672 (N05, L=225, class/area Dao/beta on
20 Aug). This region produced an M1 flare (R1-Minor) at 20/0152 UTC.
No Earth-directed CMEs were observed during the period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels from 14-16 Aug and again from 18-20 Aug. A decrease to
moderate levels was observed on 17 Aug coinciding with the arrival
of a positive polarity coronal hole high speed stream (CH HSS). The
largest flux value of the period was 23,392 pfu observed at 20/1540
UTC.

Geomagnetic field activity ranged from quiet to G1 (Minor)
geomagnetic storm levels. The period began under the waning
influence of a negative polarity CH HSS. Solar wind speed decreased
from near 600 km/s to around 360 km/s by 16 Aug while total field
was between 3-5 nT. Early on 16 Aug, total field began to increase
to a maximum of 13 nT at 17/0740 UTC while the solar wind speed
slowly increased to around 780 km/s by late on 19 Aug as a polar
connected, positive polarity CH HSS became geoeffective. By the end
of the period, solar wind speeds decreased to near 650 km/s while
total field values had decreased to 3 nT. The geomagnetic field
responded with quiet levels from 14-16 Aug, followed by quiet to G1
(Minor) storm levels from 17-20 Aug.

FORECAST OF SOLAR AND GEOMAGNETIC ACTIVITY 21 AUGUST-16 SEPTEMBER 2017

Solar activity is expected to be at low levels with a chance for
M-class (R1-R2, Minor-Moderate) activity from Regions 2671 and 2672
from 21 Aug-02 Sep and again from 08-16 Sep when both regions return
to the visible disk. Very low levels are expected from 03-07 Sep.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to reach high levels from 21-30 Aug, 01-07 Sep, 11-13 Sep,
and again from 15-16 Sep due to recurrent CH HSS influence.

Geomagnetic field activity is expected to be at unsettled to active
levels from 21-22 Aug, 30 Aug-02 Sep, 08-09 Sep, and from 13-16 Sep
with G1 (Minor) storm levels likely on 31 Aug, and 13-16 Sep due to
recurrent CH HSS activity.

BBC To Shut Down Additional Medium Wave Transmitters

BBC Radio Devon, Radio Lancashire and BBC Essex will be heard on fewer frequencies; BBC Radio Sussex, Surrey, Humberside, Wiltshire, Nottingham, Kent, and Lincolnshire will no longer be accessible on medium wave at allAugust 21, 2017

LONDON — Ten BBC local radio stations will lose at least one AM transmitter this coming January as part of the BBC’s Delivering Quality First plan.
BBC Radio Devon, Radio Lancashire and BBC Essex will be heard on fewer frequencies; BBC Radio Sussex, Surrey, Humberside, Wiltshire, Nottingham, Kent, and Lincolnshire will no longer be accessible on medium wave at all, according to radiotoday.co.uk.
The BBC has turned off a number of medium-wave transmitters over the past few years and after audience feedback (or lack thereof) made the decision to turn off 13 more MW transmitters.  “We conducted detailed assessments of the coverage of each BBC local radio station on FM, MW and DAB. Following this process, we trialled the switch-off of a number of medium-wave transmitters and asked for audience feedback. Taken together, the audience feedback and the coverage data have informed which medium wave transmitters are unlikely to represent value for money in the longer term,” said Kieran Clifton, Director, BBC Distribution & Business Development, quoted in the same article.

The BBC says it knows the shut-downs will have an impact on some listeners but encourages them to listen on FM, DAB, Freeview or online instead. (Radiomagonline)

#233 Issued on Monday August 21, 2017 at 1930 UTC

Global Daily HF Radio Wave Propagation Forecast-

HF radio wave propagation condition and trend-

A deteriorated state.
An improving state.


NORTHERN HEMISPHERE RADIO WAVE PROPAGATION
80-60 (75-60) meters- poor at night and very poor at day,                                               40-30 (41-25) meters- fair at night and poor at day,                                                      20-17 (22-16) meters- fair at night and fair at day,                                                       15 (13) meters- poor at night and fair at day,                                                                  12-10 (11) meters- very poor at night and very poor at day.
Keep in mind that almost daily during the northern 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).
                   
SOUTHERN HEMISPHERE RADIO WAVE PROPAGATION-
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.

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

We are now firmly in 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 solstice.

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 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 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

Sunday August 20, 2017-

Solar activity was low.

Earth's geomagnetic field was at an unsettled level.

The three daily solar flux index (SFI) numbers were 86.4 86.0 85.4.

These are some of the highest daily SFI numbers in quite a while.                    

The official daily sunspot number (SSN) was 44.

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 were 2 earth facing sun spot groups (SSG).

Sunspot group (SSG) #12671 located near N10W03 with a complex beta-gamma-delta magnetic signature capable of producing a small in size C class solar flare, a moderate in size M class solar flare and an isolated X class solar flare.

Newly risen sunspot group (SSG) #12672 located near N06E75 with a complex beta magnetic signature capable of producing a small in size C class solar flare and an isolated moderate in size M class solar flare.

There was 0 unofficial and as of yet unnumbered earth facing sunspot group (SSG).

There was 1 moderate in size M class solar flare, an

M1.1,

and 4 small in size C class solar flares,

C9.4,
C2.9,
C1.8,
C1.0.

On Monday August 21, 2017 there was 1 small in size C class solar flare, an

C5.9.

There was 0 earth aimed (geoeffective) coronal mass ejection (CME).

No directly earth aimed (geoeffective) coronal mass ejection (CME) related high and mid latitude energetic proton storm occurred (polar cap absorption).

No directly earth aimed (geoeffective) solar flare related x-ray day side solar fade out (SFO) occurred.

No directly earth aimed (geoeffective) collapsing magnetic filament eruption occurred.

The 24 hour period 3 hour interval planetary K index (Kp) was minor geomagnetic storming conditions to quiet geomagnetic conditions of

4 5 3 2 2 3 3 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

39 and 9,

which was at minor geomagnetic storming conditions to unsettled 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 C9.45.

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

-0.41 nT south.

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

 -34 and -16 nT.

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

734 and 585 km/s.

There was a recurrent very large in size earth facing northern hemisphere coronal hole (CH) #820 (#815).

It’s attached high speed solar wind stream (HSS) was impacting earths geomagnetic field in a negative manner in the form of minor geomagnetic storming conditions.


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.

Ukraine starts broadcasting TV channels from Chonhar to occupied Crimea


Ukraine has started broadcasting TV channels in test mode to Crimea from the village of Chonhar in Kherson region's Henichesk district, according to Serhiy Kostinsky, a member of the National Television and Radio Broadcasting of Ukraine.

According to him, "digital television has been put into operation in the test mode on the Chonhar transmission tower (Kherson region). Thus, UA: CRIMEA (National Public Broadcasting Company of Ukraine), TV Channel 5, TONIS TV channel, ICTV, and Chornomorska (the Black Sea) TV are broadcasting to the territory of the North Crimea in DVB-T2 standard. Kostinsky referred to Petro Semerey, CEO of Teleseti Ukrainy, which built the Chonhar transmission tower and acting as a telecommunications operator, saying that the multiplex would start operating in the standard mode with a power of 0.3 kW from September 1, and with a power of 1 kW from November 1.

"I ask the compatriots living in Yana Kapu (the town of Krasnoperekopsk), the town of Dzhankoy, as well as Krasnoperekopsk and Dzhankoy districts, to adjust their digital antennas to Chonhar and catch the signal, fixing the Ukrainian broadcasting on video," Kostinsky said. According to him, "the company is developing another multiplex, which will involve another five Ukrainian TV channels."

#232 Issued on Sunday August 20, 2017 at 1430 UTC

Global Daily HF Radio Wave Propagation Forecast-

HF radio wave propagation condition and trend-

A deteriorated state,
A steady state,

which means that HF radio wave propagation conditions are neither deteriorating further nor improving.



NORTHERN HEMISPHERE RADIO WAVE PROPAGATION
80-60 (75-60) meters- poor at night and very poor at day,                                               40-30 (41-25) meters- fair at night and poor at day,                                                      20-17 (22-16) meters- fair at night and fair at day,                                                       15 (13) meters- poor at night and fair at day,                                                                  12-10 (11) meters- very poor at night and very poor at day.
Keep in mind that almost daily during the northern 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).
                   
SOUTHERN HEMISPHERE RADIO WAVE PROPAGATION-
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.

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

We are now firmly in 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 solstice.

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 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 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

Saturday August 19, 2017-

Solar activity was high.

Earth's geomagnetic field was at an active geomagnetic level.

The three daily solar flux index (SFI) numbers were 84.9 86.8 88.6.

These are the highest daily SFI numbers in quite a while.                         

The official daily sunspot number (SSN) was 33.

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 was 1 earth facing sun spot group (SSG).

Sunspot group (SSG) #12671 located near N10E10 with a complex beta-gamma magnetic signature capable of producing a small in size C class solar flare and a moderate in size M class solar flare.

There were 2 unofficial and as of yet unnumbered earth facing sunspot groups (SSG) near

N05E84,
S14W13.

There were 11 small in size C class solar flares,

C7.0,
C4.4,
C3.5,
C3.1,
C2.9,
C2.0,
C1.7,
C1.4,
C1.3,
C1.1,
C1.0.

On Sunday August 20, 2017 there was 1 moderate in size M class solar flare and 2 small in size C class solar flares,

M1.2,

C2.9,
C1.8.


There may have been 1 earth facing coronal mass ejection (CME) but am awaiting for the latest solar imagery to determine if it was (geoeffective) directly earth aimed.

No earth facing coronal mass ejection (CME) related high and mid latitude
energetic proton storm occurred (polar cap absorption).

No solar flare related x-ray day side solar fade out (SFO) occurred.

There was no earth facing collapsing magnetic filament eruption.

The 24 hour period 3 hour interval planetary K index (Kp) was at active to unsettled geomagnetic conditions of

4 3 4 4 4 4 3 4.

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

32 and 12,

which was at minor geomagnetic storming conditions to unsettled 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 M1.2.

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

-0.31 nT south.

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

 -51 and -24 nT.

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

728 and 548 km/s.

There was a recurrent very large in size earth facing northern hemisphere coronal hole (CH) #820 (#815).

It’s attached high speed solar wind stream (HSS) was impacting earths geomagnetic field in a negative manner in the form of minor geomagnetic storming conditions.


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 August 19-20, 2017


** BOUGAINVILLE [and non]. 3325, Aug 19 at 1146, S7-S9 music, presumed NBC; but recheck 3 minutes later at 1149 has become a JBA carrier --- rather than a quick fadedown, I bet in the interim NBC signed off uncovering RRI Palangkaraya. Perhaps Ron or someone had kept listening and can confirm. Our sunrise now 1153 UT, latening at the rate of 5 or 6 minutes per week.

3325, Aug 20 at 1149 music at S8-S6, 1152 drops to S6-S5, tho similar weak music. Wonder if the same transition happened (Glenn Hauser, Enid OK, DX LISTENING DIGEST)

** COLOMBIA. 5910.368, Aug 19 at 0601, tropical song, S9-S8, better than usual, 0615 ID as ``Alcaraván Radio`` --- yes that`s what they really say, not Radio Alcaraván (Glenn Hauser, OK, DX LISTENING DIGEST)

** CUBA. 14680, Aug 20 at 0109, JBA talk, // 7340 as second harmonic of RHC; meanwhile, 14670 CHU is inaudible, even tho it is no longer on 7335. 2 x 7850 = 15700 where one should seek it if propagation ever be excellent. Not surprising, as K index is 4 amid G1 storms. Perhaps Sun will be putting on an unusual show if this keep up at totality (Glenn Hauser, OK, DX LISTENING DIGEST)

** CUBA [non]. 7365, August 20 at 0516, R. Martí playing rock song in English mixed with ``CW``, apparently SFX in the music rather than part of the jamming underneath. Various dits unseemed real Morse code (Glenn Hauser, OK, DX LISTENING DIGEST)

** MEXICO. 710, August 20 at 1133, promo news show lunes a viernes 5:40-6:45 am, on ``La Ranchera de Cuauhtémoc, 89.7 FM``, XEDP jingle and back to music. Dominant signal now.

620, Aug 20 circa 1135, no sign of XEBU, Chihuahua2, tho other NW Mexicans are in on 550, 650, 710, etc. So wonder if it`s still on AM? (Glenn Hauser, OK, DX LISTENING DIGEST)

** NEW ZEALAND. 9700, Aug 19 at 0617, surprised to find RNZI back here, during discussion of MAD; only a JBA carrier on 9630 where it moved July 28, presumably to avoid clash with Romania at 0600 on 9700 --- but nothing of that audible now underneath. 9630 now has a JBA carrier, probably the Brazilian apparition. RNZI sked as of Aug 19:
still show 9630 at 0459-0658, so did someone forget and go back to the old frequency? 7425 at 1146 is at good level, implying it`s 100 kW still/again on the NNE antenna rahther than the NNW.

9630, Aug 20 at *0459, Bell Bird from RNZI back here after switch to 9700 last night (Glenn Hauser, OK, DX LISTENING DIGEST)

** OKLAHOMA. 1040, Aug 19 at 1800 UT, YL with Fox News, running ahead of // 1000 KTOK OKC. Hmm, could this be WHO barely on groundwave, or the Metroplex station? NO! I forgot that local 960 KGWA puts spurs on plus/minus 80 kHz, as so IDed at 1805 UT. The other one is more blocked by KRVN, and neither can be heard at night (Glenn Hauser, OK, DX LISTENING DIGEST)

** OKLAHOMA. 1157 & 1183 kHz, Aug 19 at 1757 UT, IBOC noiseblobs peaking here, i.e. out of KFAQ 1170 Tulsa. Had not heard any IBOC from them, day or night, for many weeks/months (Glenn Hauser, Enid, DX LISTENING DIGEST)

** OKLAHOMA. 3450, Aug 20 at 1154, JBA talk on the R75 with preamp-2 but gone with 1 or none; suspect an image or harmonic mix --- CBS Sports Radio ID which means it`s from 1390 KCRC, but haven`t figured out the math of possible mix with 960 KGWA (Glenn Hauser, Enid, DX LISTENING DIGEST) 

** SOLOMON ISLANDS. 9545, Aug 20 at 0459 tune in just in time to hear a JBA carrier which cuts off at 0500, presumed SIBC, which Bryan Clark, NZ, recently reported reactivated on this band.

5020, Aug 20 at 1157, very poor carrier in splash of 5025 Cuba, certainly SIBC and this one cuts off at 1200* sharp (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A [and non]. WORLD OF RADIO 1891 monitoring: confirmed Friday August 18 at 2330 on WBCQ, 9331.520v-CUSB, fair (Glenn Hauser, OK, DX LISTENING DIGEST)

Can anyone in Europe confirm whether HLR is back on 7265 as it is supposed to be? Via UTwente, nothing but noise heard instead of World of Radio at 1431 (Glenn, 1431 UT Sat Aug 19, dxldyg via DX LISTENING DIGEST)

Only China Radio International in Sinhala at 1441 on 7265 via Kashi, no signal from HLR & WOR -- 73! (Ivo Ivanov, Sofia, Bulgaria, Equipment: Sony ICF-2001D 30 m. long wire, ibid.)

Hi Glen[n], Yes, I'm just listening to World of Radio on there at the moment. Nothing was audible until around 1410 UT when it suddenly faded up here, average to fair signal at the moment.

I've often checked the Twente SDR during the afternoons and Channel 292 [6070] has not been audible on it, even though it was being received here in north west England. Just the propagation I think, it must be passing right over the Netherlands at that time of day, and I'm just in the right location for 6/7 MHz skip (Alan Gale, ibid.)

GERMANY, 7264.998, HLR via Schwerin Göhren, listen to the S=6-7 Signal in southern Germany, at 1448 UT on Aug 19. Glenn's WoRadio program in progress. 2 Hertz frequency lower side, Also S=5-6 poor signals from Asia adjacent, 7260 PBS Xinjiang Chinese from Urumqi China and 7270, some 3-4 different programmes mixture, terrible sound, TWN and CHN jamming, another Hohot Mongolian language sce, probably also AIR Madras in Sinhala ??? 73 wolfie df5sx (Wolfgang Büschel, ibid.)

WOR 1891 confirmed Saturday Aug 19 at 2230 on WBCQ, 9331.36v-CUSB, good. Also confirmed Sat Aug 19 at 2300 on WRMI 11580, S9+20 to S9. Also confirmed UT Sunday Aug 20 after 0200 on WRMI 11580, fair. Also confirmed UT Sunday Aug 20 starting 0331 on WA0RCR, 1860-AM, fair.

(Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 9930, Sat Aug 19 at 1800, WTWW-2 is still missing from this frequency, no `Theater Organ in the Ozarx`. 9475 WTWW-1 remains on but undermodulated/distorted. 12105 WTWW-3 remains totally off. It seems that the site may have had a lightning strike messing up at least two of the transmitters. Once modulation modules have been damaged, you can`t compensate by trying to force more audio thru them; that merely over-drives them, causing distortion, a symptom we encounter repeatedly at other SW stations (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 1130, Aug 19 at 1758 UT, weak signal of music? too weak to be KLEY nearby Wellington KS; also inferior to 1120, 1140 and 1150 stations. KLEY had been AWOL earlier, came back, and may have been off for some time again, not checked for recently. 

1130 KWKH Shreveport would not be playing music except incidentally during sports talk. There is another possibility, 25 kW direxional daytimer KTMR Converse TX (Houston market), listed last year as Spanish religion. Pattern is flattened with a null toward KWKH, of course, major lobes WNW/ESE, including some to the NNW, ourway. But really too far for daytime over-Texas groundwave, except maybe a remnant (Glenn Hauser, OK, DX LISTENING DIGEST)

BBC braces for backlash over North Korea service

The BBC is braced for a backlash from the North Korean government about the launch of a new service targeted at the country amid growing international tensions over its nuclear missile tests.
Francesca Unsworth, the director of BBC World Service, said the corporation was wary about launching the new North Korean service next month due to the likely opposition from the government but insisted the fragile political situation vindicated the move.
In an interview with the Guardian, she said: “We are reaching an incredibly febrile, dangerous atmosphere at the moment about that whole story, and isn’t it terrible for the people of North Korea that the only information that they getting about any of this is that woman who goes on North Korean television every night?
“We talked for many years about whether it was worthwhile doing something for the most in-need country of the world. This is right at the head of the BBC’s mission to bring independent news to people most in need – and Korea is the country most in need, followed by Ethiopia and Eritrea.”
The service will launch just weeks after Donald Trump, the US president, threatened to unleash “fire and fury” on North Korea, which responded by announcing a detailed plan to fire missiles at the US Pacific territory of Guam.
Korean is one of 12 new language services being launched by the BBCover the next few weeks in the biggest expansion of the World Service since the 1940s. The expansion involves hiring 1,400 staff and is backed by £289m of funding from the government. Other services that are launching include Pidgin, which is spoken by 75 million people in Nigeria, Punjabi and Serbian.
Tony Hall, director general of the BBC, said the new services marked “the start of a new chapter for the BBC” and called the World Service “one of the UK’s most important cultural exports”.
However, Unsworth said the North Korean embassy in London had told the BBC “in no uncertain terms” that they did not want the Korean service to be launched.
The service will broadcast a half-hour radio programme daily, that will go out in the middle of the night so that, in the words of Unsworth, “people have the opportunity to listen under their bedclothes without telling the neighbours”.
On the potential reaction of North Korea, she added: “I met with the embassy here in London and they told us in no uncertain terms that they didn’t want us to launch this service. But one of the things I did say to them, and I think that this is important, is that we are not dissident radio.
“We are there to explain their perspective on this, we are not there to be the voice of opposition. But of course we are not on the side of governments, we are there on the side of people. That is our remit and it always has been.
Half the Korean team will be based in London with the other half in Seoul. At least one person in the team has a North Korean background.
Unsworth said it was a “tough challenge” trying to ensure the service reaches audiences in North Korea but pointed to research by KBS, the South Korean broadcaster, which found that a third of defectors from the country claim to have had access to foreign broadcasts. She also said evidence suggests that young people in North Korea are not as beholden to the regime as their parents and there is an appetite for learning information not provided by the government.
Unsworth joined BBC local radio in 1980 before rising up the ranks to become home news editor, then head of political programmes and head of newsgathering. She was named the boss of the World Service in 2014.
Unsworth said the World Service has become even more important due to the spread of fake news and the expansion of state-backed services such as Russia Today and Chinese news providers in Africa.
“If RT were to criticise the Kremlin they would be off the air quite quickly, whereas if the BBC holds British foreign policy or anything up to scrutiny, well we are not going to be off the air,” she said. “The Foreign Office may be writing the cheques [to fund the World Service] but there is no question that they would be able to phone up and influence any editorial agenda that we are doing.
“In a way the ones that I am more worried about are the Chinese. The Chinese are investing in Africa for instance big time and and they really recognise that if you are going to put investment into infrastructure in these countries then the broadcasting media landscape goes alongside that.
“We are in danger of handing over the international media space to people who do not have the values of independence, free and fair without favour, and they are not impartial. All over the world I see our services operating in countries increasingly under pressure from governments clamping down on media freedom.”
World Service is expanding at a time when the BBC find itself under scrutiny about pay. The publication of the salaries paid to the BBC’s top earners led to criticism about a gender pay gap at the corporation while PwC, the accountancy firm, was hired to review apparent disparities between how much employees on the World Service are paid compared to those in the UK news department.
Unsworth refused to reveal the details about the review but said she would be writing to staff about it in the next few weeks. She added: “Obviously the staff think there is an issue or they wouldn’t have asked us to look at it. So we are looking at it.”
The World Service boss admitted that the publication of the list of salaries paid to stars such as Chris Evans had affected the mood at the BBC.
“I would be lying if I said it hadn’t. There is a bit of a febrile atmosphere I would say, in all truth,” she said. (The Guardian)
