X5-Class Solar Flare is the strongest of Solar Cycle 25

Many thanks to SWLing Post contributor, Troy Riedel, who shares the following news from Spaceweather.com:

GEOMAGNETIC STORM WATCH (G2): A CME launched into space by yesterday’s X5-class solar flare (see below) *does* have an Earth-directed component. According to a NASA model, it should strike our planet on Jan. 2nd. G2-class geomagnetic storms are possible when the CME arrives. CME impact alerts: SMS Text

MAJOR X-CLASS SOLAR FLARE: Mere hours after emerging over the sun’s eastern limb on Dec. 31st, big sunspot AR3536 erupted, producing a major X5-class solar flare. NASA’s Solar Dynamics Observatory (SDO) recorded the extreme ultraviolet flash:

This is the strongest flare of Solar Cycle 25 (so far) and the most powerful eruption the sun has produced since the great storms of Sept. 2017.

Radiation from the flare has caused a deep shortwave radio blackout over the Pacific Ocean: blackout map. Mariners and ham radio operators may have noticed loss of signal at all frequencies below 30 MHz for more than 60 minutes after the flare’s peak (2155 UT).

X2.8-Class Solar Flare: Strongest of this solar cycle

Many thanks to SWLing Post Contributor, Troy Riedel, who shares the following news via Spaceweather.com:

(UPDATED) STRONGEST FLARE OF THE CURRENT SOLAR CYCLE:

Sunspot 3514 erupted on Dec. 14th (1702 UT), producing a strong X2.8-class solar flare. This is the strongest flare of Solar Cycle 25 (so far) and the most powerful eruption the sun has produced since the great storms of Sept. 2017. NASA’s Solar Dynamics Observatory recorded the extreme ultraviolet flash:

Radiation from the flare has caused a deep shortwave radio blackout over the Americas: blackout map. Ham radio operators may have noticed loss of signal at all frequencies below 30 MHz for more than 30 minutes after the flare.

This explosion probably launched a fast-moving coronal mass ejection (CME) Soon after the blast, the US Air Force is reported a Type II solar radio burst, which typically comes from the leading edge of a CME. Based on the drift rate of the radio burst, the CME’s velocity could exceed 2100 km/s (4.7 million mph).

Confirmation: Newly-arriving images from the Solar and Heliospheric Observatory (SOHO) show a lopsided halo CME:

Although this CME is not squarely aimed at Earth, it does appear to have an Earth-directed component. A glancing blow is likely on Dec. 17th. Solar flare alerts: SMS Text

Abductees’ relatives record radio messages for broadcast to North Korea (NHK)

Family members of Japanese nationals abducted by North Korea have recorded encouraging messages for a radio broadcast aimed at the country.

The messages were recorded in Tokyo for Free North Korea Radio, a shortwave broadcaster. Its daily radio program is run by a group of people who defected from the North to South Korea.

The abductees’ relatives called on their loved ones never to give up until they are rescued.

The leader of the relatives’ group, Yokota Takuya, is a younger brother of Yokota Megumi, who was abducted in 1977 at the age of 13. He asked his sister how she is doing. He also said he is sorry that she has had to spend a long time in North Korea without freedom.

He added that the relatives will never give up until they achieve the return of all the abductees.

His twin brother, Yokota Tetsuya, told his sister about their parents. He said that their father, who died three years ago, thought about rescuing his daughter every day.

He added that their 87-year-old mother often falls over, but is doing well. He vowed to get back his sister and asked her to stay healthy until she can be reunited with her mother.

Japanese Prime Minister Kishida Fumio said last month that he wants to start high-level talks under his direct control to hold a summit with North Korea at an early date.

Yokota Takuya said after the recording that he wants the Japanese government to continue its steady diplomatic efforts until all the abductees are returned.

He expressed hope that a Japan-North Korea summit can be held and that North Korean leader Kim Jong Un will decide to hand over all the abductees. [Read the full story and watch the video here…]

New Book: Exploring Space Weather with DIY Magnetometers (Amazon)

Many thanks to SWLing Post contributor, Sten Odenwald, who writes:

Hi Thomas!

Thanks so much for your contribution to the History of Space Weather book I published several years ago!

I have just published a new book I think you might be interested in. It’s called Exploring Space Weather with DIY Magnetometers, and it’s now available at amazon.com (see below). It provides step-by-step designs for building six sensitive instruments for under $60.00 that can measure real-time changes in Earth’s magnetic field.

If you are interested in such a building project, or you know of a family member, teacher, or even a student looking for a science fair project, this book will show you how to build these instruments. I also provide examples of storm events that were actually detected by each design so you can see what typical data looks like. For additional examples and updates, visit my blog page at http://sten.astronomycafe.net/diy-magnetometers/

Thanks again for your help!

Many thanks to SWLing Post contributor, Paul Walker, who shares the following tip:

It appears they are now operating at US night times now. For the longest time, as you may be aware, they were only on 9275 kHz during the day.

Sometime around mid last week, they were being reported on 15150 kHz as well.

And I finally logged them too.. nice signal on 15150 kHz here just after 0400!!

Radio Waves: Waves Around Earth’s Core, New Australian Communications Minister, Shipping Forecast Future, and Hams Accused of Being Spies

Radio Waves:  Stories Making Waves in the World of Radio

Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!


Giant Magnetic Waves Have Been Discovered Oscillating Around Earth’s Core (Science Alert)

Earth’s interior is a far from quiet place. Deep below our surface activities, the planet rumbles with activity, from plate tectonics to convection currents that circulate through the hot magmatic fluids far underneath the crust.

Now scientists studying satellite data of Earth have identified something inside Earth we’ve never seen before: a new type of magnetic wave that sweeps around the surface of our planet’s core, every seven years.

This discovery could offer insight into how Earth’s magnetic field is generated, and provide clues of our planet’s thermal history and evolution – that is, the gradual cooling of the planetary interior.

“Geophysicists have long theorized over the existence of such waves, but they were thought to take place over much longer time scales than our research has shown,” says geophysicist Nicolas Gillet of the Université Grenoble Alpes in France.

“Measurements of the magnetic field from instruments based on the surface of Earth suggested that there was some kind of wave action, but we needed the global coverage offered by measurements from space to reveal what is actually going on.

“We combined satellite measurements from Swarm, and also from the earlier German Champ mission and Danish Ørsted mission, with a computer model of the geodynamo to explain what the ground-based data had thrown up – and this led to our discovery.”

Earth’s magnetic field is the subject of much fascination for scientists. Research to date suggests that the invisible structure forms a protective ‘bubble’ around our planet, keeping harmful radiation out and the atmosphere in, thus allowing life to thrive. [Continue reading…]

‘A link across time’: how shipping forecast will outlast Radio 4 long wave (The Guardian)

Boats have not needed the broadcast for decades but radio bosses know nostalgia for it runs deep

Radio 4’s shipping forecast is a national institution, with millions of listeners reassured by the thought that, somewhere out at sea, British fishers are patiently waiting by their radios to find out whether there is a gale warning in Rockall or Cromarty.

Yet the announcement that Radio 4’s long wave signal will be shut down as part of the BBC’s latest cuts has left many wondering how the country’s fishing fleet will cope without access to the four-times-a-day updates.

The slightly less romantic reality, according to Mike Cohen of the National Federation of Fishermen’s Organisations, is that his members have not needed Radio 4 for decades. Modern fishers have far more accurate devices to warn them about the wind and rain: “Even the small 15-metre boats in Bridlington have satellite internet these days. I’ve had video calls from people in the middle of the sea.”

Yet that does not mean they are immune to the charms of Sailing By, the music that heralds the forecasts and was designed to help captains adjust their radios: “That theme tune is a link to other times, other people, other places. There’s as much a fondness among fishermen for that as there is for the rest of us.”

When the fishers’ trade body asked its members how they felt about the shipping forecast one said it “acted as a link across communities, a link across time”. Another added: “For us it is a bygone age but for many older folk it is a reassuring connection to the past.”

The BBC plans to end dedicated programming on its Radio 4 long wave frequency next year, which could mean the loss of two of the current four shipping broadcast updates. The early morning and late night forecasts will remain on FM, DAB and online broadcasts. But the loss of the long wave signal – accessible far from the British mainland – confirms they will essentially be nostalgia pieces, more about waking the nation up or lulling listeners to sleep.

Two Brits arrested in Albania as police accuse them of spying after seizing radio gear (Southgate ARC)

Two Britons were quizzed on allegations of espionage by officers at Tirana International Airport in Albania after police discovered sophisticated Kenwood radios in their luggage

Two Britons have been arrested by Albanian spooks and accused of spying after border police found radio transmitters in their luggage.

The pair were quizzed on allegations of espionage by officers at Tirana International Airport after they discovered sophisticated Kenwood radios in their luggage.

They told the officials they were IT engineers who were carrying the amateur gear to indulge their hobby while on holiday in Albania.

One suspect was registered as using a “ham radio” in the Tirana region on online profiles, which also say he specialises in “electronic warfare”.

Albanian police confirmed that they have opened a probe over allegations of “spy activities” and “espionage”.

A source said: “It’s highly unusual to be carrying this sort of equipment and even more strange for someone to be stopped and accused of being a covert agent.”

The two Britons were held on May 30 and then allowed to return to the UK. However they remain under investigation, police say. The electronic kit by Kenwood – which makes a range of cutting edge communication devices – was sent to the Albanian Criminal Laboratory for further examination.

“Cannibal CME” to hit Earth during early hours of March 31, 2022

Many thanks to SWLing Post contributor, Ed, who writes:

Readers of the SWLing Post blog might be interested in leaning that a “Cannibal CME” is approaching Earth. The Wikipedia page about the Carrington Event says it was probably 2 CME’s in rapid succession -like this description from SpaceWx of what’s coming:

Estimated time of arrival: March 31st

Space Weather News for March 29, 2022
https://spaceweather.com
https://www.spaceweatheralerts.com

A ‘CANNIBAL CME’ IS APPROACHING EARTH: A strong G3-class geomagnetic storm is possible later this week when a ‘Cannibal CME’ hits Earth’s magnetic field. It’s a ‘cannibal’ because it ate one of its own kind en route to our planet. The mash-up of two CMEs could spark naked-eye auroras visible from northern-tier US states.

RNZ and TVNZ to merge (RadioInfo)

New Zealand’s Minister for Broadcasting and Media Kris Faafoi has announced the government’s decision to create a new public media entity by merging RNZ and TVNZ.

According to Faafoi, ensuring New Zealanders continue to have access to reliable, trusted, independent information and local content sits at the heart of the decision.

“The public media sector is extremely important to New Zealanders in providing them with high quality, independent, timely and relevant media content,” Faafoi said.

“But we know the media landscape is changing and the sector is having to adapt to increased competition, changing audience demands and ways of accessing media, falling revenue, and new and emerging digital platforms. We need public media which is responsive to these changes and can flourish.

“RNZ and TVNZ are each trying to adjust to the challenges, but our current public media system, and the legislation it’s based on, is focused on radio and television.

“New Zealanders are among some of the most adaptive audiences when it comes to accessing content in different ways; like their phones rather than television and radio, and from internet-based platforms. We must be sure our public media can adapt to those audience changes, as well as other challenges that media will face in the future.”

“The new public media entity will be built on the best of both RNZ and TVNZ, which will initially become subsidiaries of the new organisation. It will continue to provide what existing audiences value, such as RNZ Concert, as well as better reaching those groups who aren’t currently well served; such as our various ethnic communities and cultures,” Faafoi said[…]

Technologies old and new keep Ukrainians in touch with the world (The Economist)

Battery radios and satellite internet both have jobs to do

In communist Eastern Europe a shortwave radio was a vital piece of equipment for anyone wanting to stay ahead of the censors. Stations such as the bbc World Service, Radio Free Europe and Voice of America broadcast news, entertainment and rock-and-roll across the Iron Curtain.

After the cold war ended, shortwave radios gave way to television and the internet, and the broadcasts were wound down. But on March 3rd, in the aftermath of Russia’s invasion of Ukraine, the bbc announced their return. The World Service has begun nightly news broadcasts into Ukraine and parts of Russia (see map).

Significant X-class solar flare (Southgate ARC)

There was a global eruption on the sun today. It started with a powerful X1-class solar flare from sunspot AR2887.

The blast created a massive tsunami of plasma in the sun’s atmosphere, which rippled across the entire solar disk. A CME is probably heading for Earth, raising the possibility of a geomagnetic storm on Halloween. More information and updates @ Spaceweather.com.
