Highlights of Solar and Geomagnetic Activity 27 April - 03 May 2026

Solar activity reached moderate levels on 27 and 18 Apr due to M-class (R1-Minor) activity from Region 4425 (N05, L=162, class/area=Ekc/320 on 28 Apr) and 4420 (S18, L=246, class/area=Eki/300 on 21 Sep). Region 4420 produced the strongest flare of the period, an M1.5/Sn (R1) flare at 28/1353 UTC. The region also produced two Type II radio sweeps alongside C-class activity. The ejecta associated with the activity originated from near the NW limb and was not suspected to contain an Earth-directed component. 

The other 13 numbered active regions on the visible disk were either mostly quiet or only produced C-class X-ray activity. No other Earth-directed CMEs were identified in available coronagraph imagery. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was normal to moderate levels over the past seven days. 

Geomagnetic field activity reached G1 (Minor) geomagnetic storm levels on 30 Apr and active levels on 01 May due to the influence of a negative polarity CH HSS. Total magnetic field strength reached a brief peak of 14 nT on 30 Apr, with Bz reaching as far south as -12 nT. Solar wind speeds peak at just over 500 km/s early on 01 May and gradually waned over the next two days. The remainder of the period was at quiet to unsettled levels. 

Forecast of Solar and Geomagnetic Activity 04 May - 30 May 2026

Solar activity is likely to be at low levels with a chance for M-Class (R1/R2-Minor/Moderate) throughout the outlook period due to the flare potential of multiple regions on the visible disk as well as multiple complex regions due to return from the farside.  

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is likely to reach high levels on 15-20 May due to influence from a recurrent, negative polarity coronal hole. The remainder of the outlook period is expected to at normal to moderate levels. 

Geomagnetic field activity is expected to reach G1 (Minor) geomagnetic storm levels on 15-17 May; active levels are likely on 08 May, 18 May, 23 May, and 27 May; unsettled levels are likely on 04 May, 09 May, 21-22 May, and 27 May. All enhancements in geomagnetic activity are forecast in anticipation of influence fron multiple, recurrent, coronal hole HSSs. The remainder of the outlook period is expected to be at mostly quiet levels.

DX Central - SEDAP: The World’s Most Advanced Sporadic Es Data Analysis Dashboard for the FM DX Community

 


SEDAP: The World’s Most Advanced Sporadic Es Data Analysis Dashboard for the FM DX Community

OR IMMEDIATE RELEASE
DX Central Unveils SEDAP: The World’s Most Advanced Sporadic Es Data Analysis Dashboard for the FM DX Community

MANDEVILLE, La. — April 29, 2026 — DX Central is proud to announce the official launch of version 2.0 of our popular Sporadic Es Data Analysis Project (SEDAP), a revolutionary, interactive intelligence dashboard designed to decode the mysteries of VHF propagation. Officially unlocking on Friday, May 1, 2026, at 7:45 PM CDT (0045 UTC May 2) at fmdxdata.com, SEDAP transforms nearly a decade of siloed radio loggings into a massive, cinematic data science suite, completely free of charge for the hobbyist and academic community.

Historically, analyzing Sporadic E (Es) propagation on the FM band has been an isolated effort, with individual DXers tracking their own localized season-over-season metrics and comparing notes with other DXers. SEDAP shatters that limitation by aggregating more than 95,000 North American FM broadcast logs and presenting them with brand new interactive visualizations to give DXers a whole new understanding of this elusive and magical propagation method.

"For years, our understanding of Sporadic E has been largely limited to individual observations," said Loyd Van Horn, founder of DX Central and creator of SEDAP. "By bringing all of this data together, we aren't just looking at spreadsheets anymore. SEDAP allows us to physically watch ionospheric clouds spawn, compress, and track across the continent in real-time. We can finally see what a typical season looks like on a macroscopic level."
Built on a Google Cloud BigQuery architecture, SEDAP boasts a sleek user interface featuring dynamic visualizations, including:

• The Es-Cloud Tracker: The newest and perhaps most exciting addition to the SEDAP dashboard.   The Es-Cloud Tracker is a cinematic, multi-day playback engine that maps the approximate geographic formation location of FM DX Sporadic Es ionization clouds over North America.  Openings can be “played” on a timelapse, allowing DXers to watch a simulation of the Es clouds as they develop, morph and transit throughout the day or a range of days.  
• Path Line Analysis:  In-depth analysis on the most common and productive paths to and from a DXer or station location.  Visually “see” the paths that evolved over the span of a day or date range.
• Frequency & MUF Forensics: An interactive "SDR Tuner" interface to interrogate large scale band yields, signal paths, and daily Maximum Usable Frequency (MUF) ceilings.
• Station & RDS Intelligence: Deep-dive forensics into the WTFDA station database, featuring PI-Code adoption maps, format/slogan correlation matrices, and gamified "Unheard Target" lists for US States and Counties.
• DXer Network Intelligence: Long-term seasonal performance audits and multiple normalized metrics to filter out observer bias as much as possible

“We have certainly seen a huge growth in the number of DXers both reporting receptions and the amount of receptions they are reporting thanks to improved technology and resources from SDRs to propagation monitoring through Rabbitears and the FM DX Webservers,” says Van Horn.  “So while we are not here to say one season was better than another, we can give DXers insights into Sporadic Es season that can help them strategize antenna placement and bearing, timing of monitoring, potential paths based on different periods within the season and a whole lot more. This is about improving our understanding of what happens when the ionosphere sends those FM signals back down to Earth.”
SEDAP makes no claim of ownership over the raw data presented, acting strictly as an analytical engine. The platform owes its immense capabilities to the unprecedented collaboration and public data provided by FMList.org, and the Worldwide TV-FM DX Association (WTFDA).

To protect the integrity of the database and respect the bandwidth of its data partners, SEDAP is strictly governed by a non-commercial usage policy. Automated scraping and commercial monetization are prohibited, but users are highly encouraged to explore, share, and cite the dashboard's findings.
The Sporadic Es Data Analysis Project will be accessible to the public beginning May 1, 2026. To access the dashboard, view the real-time launch countdown, or read the full data usage policy, visit fmdxdata.com.

About DX Central: Based in Mandeville, Louisiana, DX Central is a premier hub for the radio monitoring community, dedicated to advancing the hobby of DXing through live streams, online receivers, regular DX challenges and contests, educational content, and data-driven propagation analysis.

Throwback Thursday - Radio Cook Islands: A Rare Voice from the South Pacific

 


Radio Cook Islands

For many shortwave listeners, Radio Cook Islands was once considered a prized catch from the South Pacific. Broadcasting from the island of Rarotonga, its distinctive mix of island music and local programming carried the sound of a truly remote corner of the world across thousands of miles to patient DXers. Today, the station’s shortwave signal is no longer heard, but recordings and QSL confirmations remain as reminders of a time when even the smallest Pacific voices could suddenly appear in our headphones.

The reception of Radio Cook Islands was never easy, which made confirmations especially meaningful. This QSL from my collection is a reminder of just how special it was to log one of the Pacific’s classic DX signals.
A rare QSL from 1983

A radio station operated by the local newspaper, one of the world's most exotic radio stations, and one that so many DXers wanted to QSL. Radio Cook Islands has its seashell trumpet call as a tuning signal. Just 500 watts on the tropical band channel 5045 kHz.

Many DX programs and DX magazines around the world reported some years ago the demise of the shortwave service from Rarotonga (RARE-a-TONG-ga) in the Cook Islands. A fire in May 1993 destroyed the transmitter building owned by Cable & Wireless. This building housed, among many other major items of electronic equipment, the old and small transmitter used by Radio Cook Islands for their shortwave service. Thus, Radio Cook Islands has been off the air on shortwave since then, and reports indicate that there is no move to reinstate this exotic little station.

The Cook Islands lie in the South Pacific about halfway between New Zealand and Hawaii. They are made up of some eight main islands which cover a total of less than 100 square miles. The capital city is Avarua (AH-va-ROO-a), which is located on the main island of Rarotonga, and the total population of some 30,000 people are mostly Polynesian.

Captain Cook, in the year 1773, is credited as being the first European explorer to visit the Cook Islands, after whom they were named. This island paradise is made up of volcanic mountains rising from the ocean floor, together with white coral reefs encircling most of each island. Whether seen from the air or from tourist beaches, they present exquisite scenes of visual, tropical beauty. For the DXer, a radio is of course a necessity, but in the Cook Islands, so is a camera.

Way back in the wireless era, at the end of World War 1 the callsign for the maritime communication station at Rarotonga in the Cook Islands was VMR. A few years later, additional stations were erected at Aitutaki (EYE-too-TAH-kee) and Mangala (mun-GAH-la), with the callsigns VLF and VLG.

Many years later, in the 1950s, the callsign VLF was used for a short while for one of the refurbished 100 kW transmitters at the Radio Australia facility located at Shepparton in Victoria. The callsign VLF was also the Australian callsign for the American communication station at North West Cape in Western Australia, though the American callsign is NMC. In addition, VLF is also the Line Callsign for a current 100 kw transmitter operated by Radio Australia at Shepparton.

The callsign VLG was taken over in 1941 as the callsign for the 10 kw home service shortwave transmitter at Lyndhurst in Victoria. Today this is the Line Callsign of a 10 kW transmitter located at Brandon in North Queensland, which carries the Pacific service of Radio Australia.
The first broadcast station in the Cook Islands was an unofficial wartime project as a service for Allied troops. A New Zealand radio engineer modified a longwave aircraft beacon on the island of Rarotonga back in 1944, and operated it as a temporary radio broadcasting service.

In April 1954, a radio broadcasting service was inaugurated using spare time on a local communication transmitter. This station went on the air as Radio Raratonga with school broadcasts lasting an hour each, twice weekly. This service on the tropical band channel, 3390 kHz, was so popular that entertainment programs were soon added using the channel 6180 kHz. The transmitter power was usually 100 watts, though on occasions the 500 watt transmitter was used. The original callsign was ZK1ZA, which in reality was an amateur callsign. Subsequent shortwave callsigns were in the series ZK2-ZK6.

The original transmitter location was at Black Rock, but in 1961, a new facility was constructed, closer to Avarua, the capital city, and just 3-1/2 miles from the original location.

Programming on shortwave was usually in parallel to the main mediumwave channel. This was made up of local productions, as well as many relays from the BBC London, Radio Australia, and Radio New Zealand. On one occasion, in 1976, Radio Cook Islands broadcast a special DX program for the benefit of the annual DX convention in New Zealand.

When the shortwave transmitter was destroyed in the fire, that left only one mediumwave and two FM channels on the air in the Cook Islands.
The islanders living in the capital city area can hear the two stations quite clearly, and those living on the outlying islands can readily hear their official AM station, 5 kw on 630 kHz; but the international listener can no longer tune in to the Cook Islands on shortwave. It is gone forever.

Back in 1989, the Ontario DX Association printed 500 QSL cards for Radio Cook Islands, using the same original design. The AWR historic collection in Indianapolis contains three QSL cards from the (Wavescan/March 12, 2000)

Radio Broadcasting on the Pacific Islands of Tonga

 
Beautiful beaches of Tonga

Jeff: One of the island groups that still maintains broadcasts on medium wave that can be heard by DXers is the South Pacific island nation of Tonga.  Here’s Ray Robinson with the story of radio broadcasting in that country.

Ray: Thanks, Jeff.  The many scattered islands that make up the kingdom of Tonga in the South Pacific are grouped in a roughly north/south line over about 500 miles. The entire cluster of 171 islands lie northeast of New Zealand at the same latitude as the central coast of the state of Queensland in Australia.  These islands are mostly volcanic in nature, surrounded by a coral reef, and the total land area for the whole country is only about 290 square miles.

Only 45 of the Tongan islands are inhabited, and the current population is about 106,000, although more than double that number of Tongans live overseas, mainly in the USA, New Zealand and Australia.  70% of the resident population lives on the main island, Tongatapu.  The name Tonga, in many Polynesian dialects, literally means ‘southwards’, and it is thought that the archipelago became known by that name because it is the southernmost group of all the island groups in western Polynesia.

Historians state that the Polynesian peoples migrated from the Asian mainland some 4,000 years ago, and they scattered out over the many small islands in the Pacific.  It is generally considered that Tonga was settled by seafarers from Samoa around 1,000 BC.

Tonga was discovered by Europeans in 1616; the Dutch were first with several visits in the 1600’s, including by Abel Tasman in 1643.  Then came James Cook and the British Royal Navy in the 1770’s, and because he arrived at the time of a local feast to which he was invited, the name of the island group in English became the ‘Friendly Islands’ – a name which is still used to this day.  In 1797, Protestant missionaries from England settled in Tonga, and it was through them that the island chief was designated as a king, taking the throne name King George, as in England at that time.  The islands unified into a single country around 1845.

Tonga has maintained its sovereignty and remains the only Pacific nation never to have been annexed by a European power, and to have retained its monarchical government.  The Tongan monarchy follows an uninterrupted succession of hereditary rulers from one family.  Historically, these Friendly Islands entered a ‘Treaty of Friendship’ with the British government in 1900 for defence and foreign policy purposes, but without surrendering their sovereignty.  This ended in June 1970, whereupon they joined the British Commonwealth of Nations.

The first radio communication station in Tonga was established under the callsign VSB in the national capital, Nuku'alofa in 1921.  Other subsidiary communication stations were soon afterwards established on other islands, including Vava'u Island with the British callsign GON.

The first radio broadcasts from Tonga came from the American eclipse expedition on Tin Can Island in 1930, with the relay of news and commentaries back to the United States on shortwave via RCA Hawaii.

Another notable broadcast took place in May 1933 when Tonga produced a short segment that was transmitted on shortwave from station VSB and picked up by AWA near Sydney, Australia for inclusion in a very memorable program for that era, the "South Seas Broadcast."

On July 4, 1961, the Tonga Broadcasting Commission (TBC), solely owned by the government of Tonga, inaugurated the first regular radio broadcasting station in Tonga under the callsign ZCO with 10 kW on 1020 kHz.  This callsign was changed to A3Z exactly fourteen years later, and the medium wave channel was changed to 1017 kHz five years later again.  There were actually two 10 kW medium wave transmitters installed in the new radio station at Nuku'alofa, one as the active unit and the other for standby usage.

In the late 1980’s, TBC inaugurated a new shortwave service in Nuku'alofa in an endeavor to bring national radio coverage to all of the islands in the Tonga group.  The initial temporary shortwave unit was made locally and it was rated at just 200 watts.  A more substantial transmitter was installed shortly afterwards and it operated with 1 kW on the 60 metre band channel 5030 kHz, and an alternate channel of 6012 kHz SSB with carrier.  The antenna system was a horizontally polarized dipole beamed to the north.

However, the Tongan shortwave service was continually plagued with problems.  The transmitter was said to be faulty, and spare parts from the manufacturers in France took a long while to arrive.  A storm destroyed the antenna system in 1993, after which the United Nations UNESCO agency provided a new 1 kW transmitter and antenna system.  However, four years later again, Cyclone Hina caused further damage to the antenna systems and to the transmitter itself.
  
The shortwave broadcasts from Nuku'alofa were always a relay of the medium wave service, and the last known broadcasts on shortwave occurred in June 1997.  By this time, a new FM service was on the air, and FM relay stations were installed on the outlying islands.

In the late 1980’s, UCB, the United Christian Broadcasters in New Zealand, announced that they had received approval to install several radio stations in Tonga; on medium wave, FM and shortwave.  It was apparently their intent to operate a shortwave station that could be heard throughout the Pacific.  A lot of preliminary work was performed, and UCB did open a medium wave station with 5 kW on 738 kHz on Tongatapu.  Ultimately, though, they decided to concentrate on FM coverage only, with low power transmitters on several of the islands.


TBC Studios and Broadcast Tower, Nuku’alofa, Tonga


I said at the beginning that the Tongan islands are mostly volcanic in nature, and in January 2022, the Hunga volcano, 40 miles north of the main island of Tongatapu, erupted, causing a tsunami which inundated parts of the archipelago, including the capital Nuku?alofa.  Comparable to the size of the 1883 eruption of Krakatoa, the Hunga volcano produced an atmospheric explosion never before documented in the modern geophysical record.  The eruption affected the kingdom heavily, cutting off most communications and killing four people in Tonga.   It took around five weeks to repair a submarine fiber optic cable used for internet and telephone connectivity.

Electricity in Tonga is mostly generated by power stations fueled by imported diesel.  As a result of the current high energy prices caused by the conflict in Iran, they are now having to ration electricity through rotating power outages called load shedding, although this seems to be mainly during overnight hours.

Today, TBC operates two free-to-air TV channels (Television Tonga and Television Tonga 2), one AM commercial radio station (TBC Radio 1, also known as Radio Tonga), one FM commercial radio station (TBC Radio 2, also known as Kool 90FM), and a 24-hour Radio Australia relay station (FM103).  The funding of TBC relies mainly on profits from its TV & radio advertising sales.

The full formal ID of Radio Tonga is:  "THIS IS THE CALL OF THE FRIENDLY ISLANDS, RADIO TONGA 1 (A3Z), NUKU’ALOFA, TONGA."

 Here’s an audio clip of Radio Tonga a few weeks ago on Saturday March 21st.  The languages used are both Tongan and English – listen out for ‘The Call of the Friendly Islands’.

 To hear the audio clip of  Radio Tonga 1, go to the audio link for April 26, 2026  at:  https://www.podomatic.com/podcasts/wavescan

The station has always been a good verifier with a distinctive QSL card, both under the old callsign ZCO, and under the current callsign A3Z.  Many of the QSL cards issued by the station carry unique postage stamps, such as one in the circular shape of a camera lens, and another in the shape of a banana.  So, if anyone manages to log this exotic MW DX catch on 1017 kHz, please let us know, and we’ll mention it here on Wavescan.

 Besides the TBC stations, there are also a half dozen or so privately owned 100 or 200 Watt FM stations, along with FM transmitters carrying China Radio International and the aforementioned Radio Australia.

 Back to you, Jeff.

Thanks to Mike Barraclough of BDXC for posting the following

Page 1 
 
At the center of the VOA’s Greenville 4,800,000 watt broadcast¬ ing complex is “Site C,” the receiving station whose courtyard is seen above. Incoming programs from Washington, D.C., pass through the Site C control console to transmitting Sites A and B. Incoming overseas teletype and voice feeds are sent to Washington.
Remotely operated rf switchgear, one of two identical units, channels nearly 3 megawatts of power to an antenna field which covers two miles and more in length ... and contains huge curtain antennas rising nearly 300 feet, and rhombics over a quarter of a mile long. Both rhombics and curtains, used interchangeably, are beamed at such distant cities as: Moscow, Prague, Cairo, Lagos, Rio de Janeiro, Santiago and Tegucigalpa.

Highlights of Solar and Geomagnetic Activity 20 - 26 April 2026


Solar activity ranged from low to high levels. The strongest events of the period were an X2.4 flare (R3-Strong) at 24/0107 UTC and an X2.5/2B (R3) at 24/0813 UTC from Region 4419 (N14, L=314,
class/area=Eki/360 on 17 Apr). The X2.4 flare had an associated Tenflare and CME signature. Modeling of the CME indicated possible influence from the far periphery of the event on 26 Apr. The X2.5
flare had an associated Type II (est 1,293 km/s), Type IV, and Tenflare (570sfu) as well as a CME signature in coronagraph imagery. Modeling of this event suggested the primary bulk of the plasma was
not on the Sun-Earth line. 

Other major X-ray events included an M6.4/1F (R2-Moderate) at 24/1815 UTC from Region 4419. The resulting CME was off the Sun-Earth line. An M6.0 (R2) flare 26/2257 UTC from Region 4420
(N16, L=225, class/area=Fki/400 on 25 Apr). As associated Type II (est 834 km/s) was reported with this event as well as a 30,000sfu burst on 245MHz. No CME signature was identified in subsequent
coronagraph imagery. 

13 other M-class (R1-Minor) events were observed over the past week with many producing radio and CME signatures. However, those events that were associated with CMEs did not contain an Earth-directed component. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 20-24 Apr and remained at normal background to moderate levels for the remainder of the report reporting period. 

Geomagnetic field activity reached G1 (Minor) storm levels on 20-21Apr due to the influence of a negative polarity CH HSS. Solar wind speeds peaked around 550 km/s and total magnetic field strength
increased to a brief peak of 10 nT on 20 Apr. The Bz component reached as far south as -8 nT during the HSS. Quiet to unsettled conditions were observed over 22-25 Apr. A negative polarity coronal
hole, with possible weak embedded influence from a CME that left the Sun on 24 Apr, caused isolated active levels on 26 Apr. Solar wind speeds remained below 500 km/s with this coronal hole. 

Forecast of Solar and Geomagnetic Activity 27 April - 23 May 2026

Solar activity is expected to reach moderate levels (R1-R2/Minor-Moderate), with a slight chance for high (R3/Strong), from 27 Apr - 04 May due to the flare potential from multiple active regions on the solar disk. The remainder of the outlook period is likely to be at low levels, with a slight chance for M-class (R1-R2). 

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels on 12 Apr, 29 Apr - 05 May, 08-14 May, and 17-21 May due to the anticipated influence from multiple, recurrent, CH HSS. The remainder of the outlook period is likely to be at normal to moderate levels. 

Geomagnetic field activity is expected to reach G1 (Minor) geomagnetic storm levels on 07 May and 15-16 May. Active conditions are likely on 27 Apr, 30 Apr, 08 May, 17-18 May, and 23 May.
Unsettled conditions are likely on 29 Apr, 01 May, 03-04 May, 09 May, and 21-22 May. All enhancements in geomagnetic activity are due to the anticipated influence of multiple, recurrent, CH HSSs. The remainder of the outlook period is expected to be at mostly quiet.
