Highlights of Solar and Geomagnetic Activity 08 - 14 July 2024



Solar activity was at low to strong levels during the period. R1 (minor) solar radiation storms were observed on 08, 10, 11, 13 and 14 Jul, R2 (moderate) storms were observed on 13 Jul and R3 (strong) storms were observed on 14 Jul. Regions 3738 (S09, L=213, class/area Fkc/1140 on 14 Jul), 3745 (S15, L=156, class/area Dro/020 on 13 Jul) and 3747 (S24, L=155, class/area Cso/180 on 13 Jul) contributed a majority of the activity. None of the activity resulted in any Earth-directed CMEs. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels. 

Geomagnetic field activity was at quiet to isolated unsettled levels with no discernible activity during the period. 

Forecast of Solar and Geomagnetic Activity 15 July - 10 August 2024

Solar activity is expected to be at low to moderate levels throughout the period. 

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at low to moderate levels. 

Geomagnetic field activity is expected to be at unsettled to active levels on 18-20 Jul due to recurrent CH HSS influences. Mostly quiet conditions are expected on the remaining days, pending CME activity.

Propagation update from the U.K.

 


RSGB
GB2RS News Team | July 12, 2024
We had another week of reasonably settled geomagnetic conditions and a high solar flux index.
The solar flux index was at 214 on Thursday 11 July, while the Kp index has been around 2 to 3 all week. That’s generally good news for HF.

However, a small coronal hole is now facing Earth and a solar wind stream flowing from this zone was predicted to reach Earth by the 13 July. This could result in an elevated Kp index and lower maximum useable frequencies, or MUFs for short. It probably won’t last too long, so expect conditions to be back to normal by tomorrow, the 15 July.

Active region 3738 is dominating the Sun’s surface but has only been the source of minor C-class solar flares and will remain a threat for moderate M-class flares. All other regions have been mostly stable.
The daytime MUF over a 3,000km path has often exceeded 24.9MHz, with some better-equipped stations reporting contacts into Australasia on the 10m band.

Nighttime MUFs over a similar distance are still consistently above 14MHz. Make the most of this as they are likely to drop as we head out of summer and into autumnal conditions.
The MUF is extrapolated from the Dourbes [DORB] ionosonde data and should only be used as a guide – it may often be higher, especially in some directions.

The most sought-after DX this week has been K8K/K8R in American Samoa. The DXpedition is testing out all systems on all bands, using CW, SSB and FT8, ahead of the upcoming Jarvis Island DXpedition. The station has been worked from the UK on the 30 to 10m bands, mainly by well-equipped stations, and has been testing the FT8 Superfox mode with some success.
Otherwise, contestants in the RSGB’s 80m SSB Club Championship on Wednesday 10 July reported fair conditions, but a very, very noisy band. Noise is often a limiting factor, especially on the lower HF bands.

Next week, NOAA predicts that the solar flux index may decline to the 180 to 190 range. Geomagnetic conditions may be unsettled today, the 14 July, with a Kp index of 4 at times. The second half of the coming week should be more settled, as long as we don’t have a coronal mass ejection.
VHF and up :

The overall picture is of unsettled weather still being around for the coming week, but there will be some temporary moments of weak high pressure to alleviate incessant rain.
As we end the current week, pressure will rise over western areas bringing a chance of Tropo for paths down the Irish Sea and across Biscay. There will also be a second period of high pressure for a time in the middle of next week, favouring the south. This gives us at least a chance of Tropo for this week’s UK Activity Contests on the 23cm and 4m bands.

The ‘unsettled’ part of the story is worth noting, especially if we get some heavy thundery downpours, which should be great for rain scatter. Continuing with scatter modes, there is always meteor scatter as a diversion and the advice is to look in the early hours before daybreak when random meteors are more likely.

Solar conditions are still not entirely settled so there remains a chance of aurora should the Kp index rise to 5 or more. The Sporadic-E season is still doing good business within Europe, but it feels as though it’s not been quite so noticeable as during June for UK stations.
The jet stream pattern is trying to help next week with several useful segments over northwest Europe, which should improve the chances of Sporadic-E paths from the UK into the continent.

Moon declination went negative again on Friday 12 July, which also corresponds to apogee, the point at which the Moon is furthest from Earth. So, Moon peak elevation and path losses will continue to fall again next week. 144MHz sky noise starts low early next week rising to a high of 2100 Kelvin on Friday.

Radio Luxembourg – The Early History, part 2

 


Thanks to Ray Robinson and Jeff White for sharing Part 2 on the history of Radio Luxembourg


Jeff: Last week, Ray Robinson reviewed some of the early history of Radio Luxembourg in Europe – specifically the year it first launched – 1933.  Now in the second part of this story, here’s Ray again continuing from January 1934.

Ray:  Thanks, Jeff.  The 1933 Lucerne Plan of long, medium and shortwave frequency allocations for radio stations in Europe became effective at 11pm UK time on Sunday, January 14th, 1934.  All over the continent during the early hours of Monday 15th, stations were adjusting their transmitters to comply with the new frequency allocations.  The Grand Duchy of Luxembourg, as we mentioned last week, had not been granted a long wave channel due to the small size of the country, and had only been assigned one medium wave channel instead.  But, when Compagnie Luxembourgoise de Radiodiffusion (CLR) opened transmissions of Radio Luxembourg that Monday, to many listeners’ surprise, they found the station had moved not to the medium wave frequency that had been allocated, but to 1304m / 230 kHz longwave.  This was a channel which under the new plan was allocated to Warsaw, Poland.  As you can imagine, this gave rise to yet more charges of piracy, even as the station continued to become more successful commercially.

It was also the 1933 Lucerne Plan which reallocated the channel used by the BBC National Programme from 1554m to 1500m / 200 kHz, which, give or take the minor adjustment that occurred in 1978 to 198 kHz, is the same channel on which it has operated for 90 years and continues to do so to this day.

Immediately after the implementation of the Lucerne Plan, chaos from interfering stations on both the long-wave and shortwave bands was noted by listeners.  Stations in a number of countries had refused to comply for various reasons, and a follow-up conference was needed to iron out the problems.  This was held in Geneva in late February 1934, and again the Government of Luxembourg sent its delegates.

On Friday 2nd March, it was announced in Geneva that a ‘pact for peace on the air’ had been reached by experts from 15 countries, including Luxembourg.  The agreement involved the changing of more than 12 long and short wavelengths in 10 countries, including the wavelengths for Radio Paris (which had been interfering with the BBC) and Radio Luxembourg.

Notwithstanding that announcement, however, it was actually Radio Warsaw that decided to shuffle down the band slightly, from 1304m / 230 kHz to 1339m / 224 kHz.  Although that was still not enough to provide 9 kHz separation to avoid interference completely, both were high power stations, and it was reported that adjacent channel splash was barely noticeable if the listeners off-tuned their wireless slightly.

During 1934, the International Broadcasting Company, which had been buying time for sponsored programmes on Poste Parisienne and Radio Normandy, began similarly buying time on Radio Luxembourg, which helped it expand its broadcast schedule considerably.  The station more than doubled its output from 40 hours/week in 1933 to 87 hours/week by 1935 and then grew to 104 hours/week in 1936.

Radio Luxembourg remained on 1304m for quite some time.  Program listings from April and May 1935, more than a year after the Geneva conference, showed the station was still on 1304m, at that time with programming in English on Sundays from 7:45am-12midnight, and during the rest of the week from 12noon-11pm.

Then, later program listings from 1938 show that by that time, Radio Luxembourg did change frequency once more, moving up the dial slightly from 1304m / 230 kHz to 1293m  / 232 kHz.  This then put an 8 kHz gap between them and Warsaw on 1339m / 224 kHz, which was enough to end the adjacent channel interference.  And, 232 kHz was the frequency on which the longwave transmitter in Luxembourg remained until the new band plan in 1978 required an adjustment to 234 kHz.

One of the first announcers on Radio Luxembourg was Charles Maxwell, who first went out to the Grand Duchy in 1936.  Here he is speaking about his early recollections in a documentary about the station that was broadcast in 1974:

And if you’re wondering why he couldn’t fly directly to Luxembourg, it was because there was no airport there!  The first small grass airfield in Luxembourg wasn’t opened until the late 1930s.

When war broke out on September 3rd, 1939, all private stations in France were ordered to close by the government.  Radio Luxembourg was taken over by the Luxembourg government for a few more weeks for special news programming, but advertising revenue had stopped completely, so it was decided the station should close also, which it did, on Friday, September 22nd, 1939.

Early in 1940, an enterprising engineer at the transmitter site decided to bury four high-power amplification tubes from the transmitter in an adjacent field, to prevent them from being used by the Germans, and in case they should be needed again after the war.

Nazi German forces eventually overran Luxembourg in May 1940 and took control of the Radio Luxembourg studios and transmitter site.  They managed to reactivate the transmitter, and in July 1940 began using it for their own propaganda broadcasts by William Joyce (known as Lord Haw-Haw) and others.

Radio Luxembourg remained under the control of the Germans until early September 1944, when the advancing American forces entered and liberated the city of Luxembourg.  Before the Germans withdrew, they attempted to destroy the station.  Their attempt failed, but they did do severe damage.

The engineer who had buried the transmitter tubes in the field adjacent to the transmitter site in 1940 dug them up again, and the station was quickly refurbished.

Sadly, Radio Normandy on the coast at Fecamp was totally destroyed during the D-Day landings on June 6, 1944, and it was never rebuilt.  Radio Luxembourg was to be the only continental broadcaster of English language commercial programs which survived into the 1940s and 50’s.

In early 1945 under US Army control, the Luxembourg transmitter was used on a different frequency and with only 50 kW to broadcast ‘black propaganda’ programming into Germany, pretending to be a German station.  The station is identified in German by its wavelength, as ‘Hello, This is Twelve Twelve Calling’ (on 1212 metres).

William Joyce was captured, and after the war he was tried for treason and hanged at Wandsworth Jail in London in January 1946.  Control of Radio Luxembourg was returned to the Luxembourg Government, and then to CLR.  In February 1946, sponsored programs were back on the air, and in the summer of that year, English programs were heard once again on 1293 metres.  A small British staff worked wonders with records that had remained hidden during the German occupation.  They were very much out of date, but at least they told the listeners, 'Radio Luxembourg is BACK on the air!'

The longwave transmitter continued to carry English language programming until the new Copenhagen band plan of 1949 went into effect.  In that plan, Luxembourg was also allocated 208 metres medium wave, 1439 kHz, and the station decided to use the longwave frequency exclusively for French language programming.  From July 2nd, 1951, the medium wave channel became the home for all German language programming during the daytime, and English language programming during the evenings, from 7:45pm-3am UK time.  There was also a short block of programs in the early evening in Italian and Dutch after the German programs closed.

Shortwave transmissions were also introduced, with the French programming being relayed on 15350 kHz, and the daytime German programming on 6090 kHz.  During the evenings on 6090, religious programming was carried in various languages up until midnight, followed by a relay of the last three hours of the regular English language programming.

The English service ended on 30th December 1992, with the medium wave channel then carrying German language programming only, until the transmitter was finally turned off for the last time on 31st December 2015.

Radio Luxembourg in French is still heard on FM stations throughout France and on various digital platforms, but the longwave broadcasts on 234 kHz were discontinued on January 2nd 2023, at midnight UTC.

Highlights of Solar and Geomagnetic Activity 01 - 07 July 2024


Solar activity was at moderate levels for the last week. There were multiple low-level M-class flares. None of which resulted in any Earthbound CMEs or energetic particle events. The regions on the disk were mostly unremarkable. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels for the first time since 23 Dec 2023. A peak flux of 119 pfu was reached on 03 Jul. Normal to moderate levels were reached on the rest of the summary days. 

Geomagnetic field activity was at quiet to unsettled levels.

Forecast of Solar and Geomagnetic Activity 08 July - 03 August 2024

Solar activity is expected to be at low to moderate levels throughout the period. 

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at low to moderate levels. 

Geomagnetic field activity is expected to be at unsettled to active levels on 08, 11 and 14 Jul due to recurrent CH HSS influences. Mostly quiet conditions are expected on the remaining days, pending
CME activity.

Shortwave Radiogram, Program 361

 


Hello friends

I'm just getting over my first-ever encounter with Covid. The symptoms nearly prevented me from producing last week's program 360. 

Thanks to Al WD4AH for watching over the @SWRadiogram X/Twitter account the past week, as I slept through almost all of the program's 360 transmissions.

It is perhaps because of the well-known Covid symptom brain fog (even more so than my usual everyday brain fog) that it did not dawn on my until too late that today is a holiday, Independence Day here in the United States. I uploaded program 361 to WINB, but there might not be anyone home at WINB because of the holiday. If we hear last week's show today at 2330 UTC (and maybe even Saturday 0230 UTC), that may be the reason. 

A video of last week's Shortwave Radiogram (program 360) is provided by Scott in Ontario (Wednesday 1330 UTC). The audio archive is maintained by Mark in the UK. The analysis is provided by Roger in Germany.

Here is the lineup for Shortwave Radiogram, program 361, 4-10 July 2024, in MFSK modes as noted:

 1:44  MFSK32: Program preview
 2:52  MFSK32: Cargo conveyor will replace 25,000 trucks*
 8:48  MFSK64: Record-Breaking Sea Temperatures Fuel Beryl

Radio Luxembourg – The Early History, part 1

 


Special thanks to Ray Robinson and Jeff White for sharing AWR Wavescan. Early DXers will recall the impact that Radio Luxembourg had on European listening.

Jeff:  You probably know that in the late 1960’s and 1970’s, Radio Luxembourg was a powerhouse Top 40 station in Europe with transmitters on LW, MW, SW and FM.  Their MW transmitter on 1439 kHz (208 metres) was rated at 1.2 MW, and in its heyday, it was by far the most successful station beaming programming in English to the British Isles, with a format and jingle package very similar to that of WABC in New York.  However, the station had a very colorful history, going right back to the early 1930’s, and Ray Robinson has been digging into the pre-World War II events that led to the creation of the station in the first place.  Here’s Ray.

Ray:  Thanks, Jeff.  Luxembourg is a small triangular-shaped country in north central Europe with a land area just under 1,000 square miles, about two-thirds the size of the U.S. state of Rhode Island.  It is squeezed between Germany in the east and Belgium in the west, and shares a short border with France in the south.  Luxembourg is one of the least densely populated countries in Europe with a total population of around 670,000.  Its government is a representative democracy headed by a constitutional monarch, Grand Duke Henri, making it the world’s only remaining sovereign grand duchy.  The city of Luxembourg lies about 117 miles from Brussels , 119 miles from Frankfurt, 230 miles from Paris, and just 300 miles from London.

I was recently researching in some British newspapers of the 1930’s for other purposes, and I came across a number of articles and program listings for Radio Luxembourg, that tell a story that I think is not well understood or documented elsewhere.  So, over the next couple of weeks, we’re going to take a look at that very interesting formative period in European broadcasting.

For our purposes, the general setting starts with the fact that the British Broadcasting Corporation (BBC) had been given its royal charter in 1927, with Scotsman Sir John Reith appointed as Director-General.  A staunch Presbyterian, Reith’s philosophy of broadcasting was that the purpose of the BBC was to inform, educate and entertain, in that order.  He greatly resisted American-style programming where the goal was to attract the largest audiences and thereby the greatest advertising revenue.  There was no advertising on the BBC (as indeed there still isn’t to this day), and most musical programming was classical in nature.  At a time when American, Canadian and Australian stations were drawing huge audiences with the broadcast of baseball, hockey and rugby games, the BBC carried little sports programming, not wanting to spend its limited airtime on football or cricket matches, regardless of how popular they may be.  On Sundays, there was no broadcasting at all before 12:30pm, so that people had time to attend church, and for the rest of the day, Sunday programming was always very somber and serious.

In the late 1920’s, a number of privately owned stations in France took advantage of this to broadcast programming of a more popular nature – dance band music, showtunes and the like – across the Channel to the British Isles.  These included Poste Parisienne, Radio Lyons, Radio Toulouse, Radio Paris, Radio Eiffel Tower, Radio Normandy and others.  But, these were not high powered stations, and could typically only reach the south of England by ground wave at night, and the north of England by sky wave.  The Midlands generally didn’t receive any signals at all from the continental stations, and of course nothing could be heard from them anywhere at all in the British Isles during the daytime.
 
To exploit this opportunity at a whole new level, a new company was set up in Luxembourg in 1930 called Compagnie Luxembourgoise de Radiodiffusion (CLR), with a franchise from the Luxembourg government to create a new radio station of not less than 100 kW, with advertising allowed to be carried, as well as foreign language broadcasts.
 
To coordinate frequency allocations in the countries of Europe, a Convention had been held in Prague in 1929.  The Government of Luxembourg had not attended, but in their absence they had been allocated the medium wave channel of 1346 kHz, or 223 metres.  This, the Convention deemed, was adequate to cover the small country.

However, the new company, CLR, had ambitions for coverage much greater than just of the country of Luxembourg itself, and had set about constructing a high powered long wave station.  They had succeeded in raising capital of 5 million French Francs, mainly from investors in France, who could see the commercial possibilities for broadcasting to the British Isles.  CLR bought a large area of land on the Junglinster plateau about 10 miles NE of Luxembourg city, and there set about constructing its first transmitter site.  Studios were built in the city itself.

Setup and construction took a couple of years, but finally on Sunday March 19th, 1933, the new station was heard.  In the UK the next day, the Nottingham Evening Post reported “The new giant transmitter, Radio Luxembourg, blossomed out into the open with a vengeance last evening, and is on a par with Radio Paris as regards strength and quality.”  At 7:35pm, they announced they were using a wavelength of 1191 metres (252 kHz) with 200 kW, the power being generated by two 800 hp diesel engines.

They remained in test mode for several months, carrying no advertising, and identifying the station as Radio Luxembourg Experimental.  Programs on Sunday evenings were in English, on Mondays they were in Italian, and in other languages on other days of the week.  Newscasts were carried nightly in French, German and English.

On Friday April 7th, about three weeks after the first tests began, a reporter in the Manchester Evening News wrote:  “Every night now I am getting fine signals from Luxembourg – Radio Luxembourg Experimental as it is announced in French.  Almost every language of importance in Europe seems to figure in these announcements.  I have heard German, English, French, Dutch, Italian and Luxembourgish (a local dialect of Flemish).  For the past two Sundays I have heard excellent gramophone record concerts announced in English for practically the whole evening.  The wavelength is definitely 1191 metres, just above Kalundborg (Denmark, which was on 1153 metres, 260 kHz – only 8 kHz higher).  I sincerely hope the station gets this or some equally good wavelength officially.  It promises to be a station of high entertainment value.”

On Sunday April 9th, it was reported that the station operated from 7-11pm with one short breakdown and one record played on the wrong side!

There were 14 stations that could be heard on long wave in the UK in 1933:

Leningrad, Russia on   857 m, 350 kHz,
Oslo, Norway   with   60    kW on 1083 m, 277 kHz,
Moscow, Russia (II) on 1115 m, 269 kHz,
Kalundborg, Denmark with      7.5 kW on 1154 m, 260 kHz,
Luxembourg with 200    kW on 1191 m, 252 kHz,
Motala, Sweden with    30    kW on 1348 m, 222 kHz,
Warsaw, Poland with 120    kW on 1411 m, 212 kHz,
Paris (Eiffel Tower) with    13    kW on 1446 m, 207 kHz,
Moscow, Russia (I) on 1481 m, 202 kHz,
BBC National Programme with    25    kW on 1554 m, 193 kHz,
Berlin (Deutschlandsender) with    60    kW on 1635 m, 183 kHz,
Paris, France (Radio Paris) with    75    kW on 1725 m, 174 kHz,
Lahti, Finland on 1796 m, 167 kHz, and
Huizen, Netherlands with       8.5 kW on 1875 m, 160 kHz.

In short – just 14 stations on LW, compared to over 30 on MW from outside the UK, plus another 6 BBC MW transmitters carrying the National Programme and the London, Midlands, North, West and Scottish Regional Programmes.

In the summer of 1933, with the growing need for more frequencies for more stations in more countries, another frequency coordination conference was convened in Lucerne, Switzerland, under the authority of the League of Nations.  This time, Luxembourg was a participant.  The BBC under John Reith was staunchly opposed to what they considered Luxembourg’s brash commercial style of programming, and considered them to be a pirate.  They asked the UK government to bring pressure to bear in Lucerne to prevent Luxembourg from being formally allocated a long wave frequency.  Whether they did or not isn’t recorded, but the upshot was that the Conference did not approve of the use of long wave frequencies for international broadcasting, preferring only to allocate them to geographically larger countries which could not adequately provide national coverage from just one or two medium wave transmitters.

Thus the Conference didn’t think the size of Luxembourg justified a long wave allocation and only assigned them a medium wave channel of 240m, 1249 kHz.  The Luxembourg delegates were dismayed and became non-signatories to the Lucerne Plan.

Radio Luxembourg’s popularity and commercial success grew steadily during 1933, primarily because it was broadcasting popular dance band music of a type not heard on the BBC, especially not on Sundays!  Broadcast hours expanded to 8am-11pm UK time, and the powerful long wave signal was comfortably heard throughout most of Great Britain during the daytime.

On Wednesday 10th January 1934, just four days before the Lucerne Plan was due to take effect, a column appeared in the Nottingham Evening Post saying:

“Although the transmissions from Radio Luxembourg are for the most part electrical recordings and in consequence ‘thin’ compared with live band concerts, they are extremely popular, the reason being the class of music put over.

During each Sunday dinner hour (meaning lunchtime) there are dance records, and in the afternoon until about 8 o’clock these electrical recordings of further dance music are radiated, all being sponsored.

Then follows a tip-top program of English music, free from advertising material, and contributed by the station orchestra.  The difference in quality – for the better – is very marked.

However, it cannot be denied that Luxembourg is a very popular station, and its popularity has been won by the BBC – on Sundays, of course, simply by the type of music transmitted.  It will be extremely interesting, therefore, to watch what happens in the Grand Duchy.”

And that’s where we’ll pick up the story next week in part 2.

AI Is Saving Money for Transmitter Users

 


Houzé: Optimized power consumption generates multiple benefits

BY RW STAFF
PUBLISHED: JUNE 26, 2024

A current Radio World ebook explores the use of artificial intelligence in radio broadcasting. This is an excerpt.

In 2018 WorldCast Systems released its first technology with artificial intelligence for FM transmitters, SmartFM, to optimize RF power based on the audio content, in real time. The company says benefits include lower power costs, reduced cooling, less maintenance, longer transmitter life and a smaller carbon footprint.

David Houzé is a product manager for WorldCast.

David Houzé
Radio World: What’s the most important recent or current trend in how artificial intelligence is being used in radio and audio?

David Houzé: We are still at the beginning of artificial intelligence in radio broadcasting but the trendiest use of AI is mainly in the studio and concerns the script generation for shows, news or weather reports.

Focus on clandestine radio - Voice of Fano

 

Uploaded June 30th to YouTube by SWL, Andre from South Africa, 29 minutes 32:

Clandestine radio stations operate underground for various reasons. They often target countries with high degrees of censorship, are used by political movements or during times of conflict by opposing sides. But how do these stations operate, and why are they founded? You can find answers to these questions in this video, in my interview with a presenter and producer from Voice of Fano.

There are a number of clandestine or underground stations targeting Ethiopia, because of the ongoing conflict situation between various ethnic groups there. I caught Voice of Fano on 15215 kHz some time ago. It is a rare station, only transmits twice a week. You can watch my first video here (Introduction and recording of station May 1st, 6 minutes 46) 

I had the opportunity to interview one of the presenters and producers, who told me the story of the station, how it operates, how programming is produced, who listens to them and more. He also provided context about the current situation in Ethiopia and the conflict against the Amhara people. There is a genocide going on in Ethiopia and very few people pay any attention. This is a rare look behind the scenes of a clandestine radio station during this time of conflict.

Voice of Fano can be heard on Wednesdays and Saturdays, from 17:00 to 18:15 UTC, on 15215 kHz. It transmits from Issoudun. This station is not listed anywhere, except in the World Radio and TV Handbook. But the time in the WRTH is incorrect, the station now transmits for 75 minutes, not 30 minutes as listed in the WRTH.

AM Radio for Every Vehicle Act to Receive Minor Technical Update

 



There will be no substantive changes to the legislation

BY RANDY J. STINE
PUBLISHED: JULY 2, 2024

A bill in the House of Representatives that would mandate AM capability in new vehicles is about to be revised, according to a person familiar with the developments. 

New information indicates that one of the original co-sponsors of the bill, Rep. Frank Pallone (D-N.J.), plans to introduce an amendment to the bill (H.R. 8449). Changes would only include minor technical updates. 

The planned amendment to the AM Radio for Every Vehicle Act comes on the heels of last week’s last-minute cancellation of a planned vote by the House Energy and Commerce Committee, which could have advanced the legislation to the full House for a vote. 

Pallone’s amendment will include “no substantive” changes to the legislation, according to the insider, and will be introduced at the next full committee markup. The amendment will clarify that the bill applies to new vehicles manufactured and sold in the United States, as well to vehicles manufactured abroad and sold in the U.S.; however, vehicles built in the U.S. but sold overseas would not be required to include AM capability.

Highlights of Solar and Geomagnetic Activity 24 - 30 June 2024

Solar activity reached moderate levels on 24-25 Jun. The largest flare was an M1.8 flare from Region 3712 (S26 L=170, class/area=Eao/220) at 24/0417 UTC. Other M1 flares were observed from Regions 3713 (S14 L=153, class/area=Ekc/360), 3720 (S06 L=54,
class/area=Dai/150), and 3723 (S19 L=08, class/area=Fai/210). Solar activity was at low levels for 26-30 Jun, with only C-class flares observed. Other notable activity included an approximately 35 degree filament erupted late on 24 Jun, centered near S19W58. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels. 

Geomagnetic field activity was reached G4 (Severe) storm levels on 28 Jun due to the arrival of a CME that lifted off the Sun on 24 Jun. Total field strengeth reached 30 nT and the Bz component reached -22 nT. Solar wind speeds increased steadily from near 300
km/s to approximately 490 km/s. Active levels were reached early on 29 Jun due to continued CME influences. Quiet to unsettled levels were observed on 24-27 Jun, and 30 Jun. 

Forecast of Solar and Geomagnetic Activity 01 July - 27 July 2024

Solar activity is expected to be low levels, with occasional M-class flares for the duration of the period. 

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at moderate levels from 01-27 Jul. 

Geomagnetic field activity is expected to be at unsettled to active levels on 01-03 Jul due to possible glancing influences from multiple CMEs. Unsettled to active levels are expected on 14-16 Jul due to influence from a recurrent, positive polarity coronal hole
high speed stream (CH HSS). Quiet to unsettled levels are expected on 05-13 Jul and 17-27 Jul.
