Farside Explosion reaches Earth

Imagine an explosion on the farside of the sun so powerful, we could feel it here on Earth. It happened on July 13th. The debris emerged in a circular cloud known as a ‘halo CME. When space weather forecasters first saw this explosion, there was a moment of excitement. It appeared to be heading directly toward Earth. However, data from NASA’s STEREO-A spacecraft indicated otherwise. The CME was heading directly away from us–a farside event.
Now for the interesting part: Although the explosion occurred on the farside, separated from Earth by the massive body of the sun, it still peppered our planet with high-energy particles. The Energetic and Relativistic Nuclei and Electron (ERNE) detector onboard SOHO recorded a surge in radiation not long after the CME appeared.
How did this radiation reach Earth? Rami Vainio, a professor of space physics at the University of Turku (Finland), who works with ERNE data says “it’s not possible to answer that question definitely without a detailed analysis involving multiple spacecraft.” However, she speculates that the lift-off of the CME may have created a global shock wave on the farside of the sun. Particles spilling over the edge might have spiraled toward our planet.
Of particular interest are the green data points (51 to 100 MeV). These are the most energetic protons ERNE can detect. An uptick in green after the CME indicates unusually “hard” radiation—the kind accelerated in the leading ed8ge of a fast-moving CME.
The source of the blast might have been the same sunspot (AR2838) that produced the first X-flare of Solar Cycle 25 on July 3rd. That sunspot is currently transiting the farside of the sun approximately where the CME came from. Within the next week AR2838 is expected to return–and then, maybe, the real fun begins. Stay tuned!

A big Glowing Cloud of MarsDust

Dust storms on Mars are bigger than we thought; they even spill into space. According to a recent paper in JGR Planets, Mars appears to be leaking dust, filling a huge volume of the inner solar system with gritty debris. You can see it with your naked eye. The bright triangle in this image from the Haleakalā Observatory in Hawaii is marsdust.

It’s called Zodiacal Light, and astronomers have long wondered what causes it. The usually faint triangle is sunlight scattered by dust in the plane of our solar system. The dust, it turns out, comes from Mars.

NASA’s Juno spacecraft flew through the dust cloud en route to Jupiter between 2011 and 2016. Dust grains smashed into Juno at about 10,000 mph, chipping off submillimeter pieces of spacecraft. Juno’s oversized solar arrays turned out to be excellent dust detectors, registering as many as 200 hits per day.

Ironically, the sandblasting allowed researchers to map the cloud for the first time. One theory of Zodiacal Light held that asteroids were responsible. Yet, as Juno flew through the asteroid belt toward Jupiter, impact rates sharply dropped, sometimes to zero. Asteroids were not the answer. Instead, they realized, the dust must be coming from Mars. Orbital elements of the dust grains essentially match that of the Red Planet.

Mars is the dustiest place in the Solar System, with dust storms that envelop the entire planet for months. But how does this dust escape? During storms, dust is sometimes launched to very high altitudes in the Martian atmosphere; researchers call it ‘rocket dust’. However, leaving Mars requires overcoming escape velocity (~5 km/s), and even rocket dust has trouble doing that. Dust grains would have an easier time launching from Phobos and Deimos; however, those small moons don’t produce enough dust to explain the Zodiacal Light.

So, there’s still a mystery here. Mars has the dust, but researchers haven’t yet figured out how Mars delivers it. Lead author John Leif Jørgensen (Technical University of Denmark) and colleagues hope other scientists will help them solve this final piece of the puzzle.

KL7RRC Alaska IOTA News

Sunday, July 4, 2021 2200UTC
Members of the Russian Robinson Club, operating as KL7RRC from Alaska’s Adak Island (NA-039) are sad to report that due to circumstances beyond their control, they will be cutting short this IOTA activation originally set to occur on both Adak and Kiska Island (NA-070).
You may recall that original plans were for the five member team to fly into Adak and be met by a chartered sailboat. Two weeks ago, SV Seal was one day from Dutch Harbor to pick up the team’s gear when an unfortunate medical emergency forced it to return and cancel the charger.
Tim NL8F, who lives in Dutch Harbor, AK was able to locate a suitable replacement vessel to take the team out the 240 miles to Kiska with the “new” vessel picking them up in Adak and transferring them to Kiska on July 6 or 7.
The team agreed to continue with the project and flew to Adak on Wednesday, June 30. For the past five days they have set up their stations and antennas and currently QRV with three stations.
However it was learned earlier today that a mechanical failure on this new vessel has forced it to cancel as well. Today, efforts were made in Adak trying once again to locate a suitable vessel. After exploring all possibilities and in consideration of safety factors involved with sailing out into some of the most difficult waters of the Bering Sea, it was collectively decided to not further pursue last-minute options. The team is obviously disappointed in this outcome but feel the decision being made is in the best interest of safety. They have also agreed to pursue another attempt to get to Kiska next year.
Meanwhile, KL7RRC will continue to operate from Adak until Friday, July 9 in hopes that everyone still needing NA-039 will find a way into the log.
Conditions from Adak have been good and their log shows over 5,200 QSO‘s following four days operation. But the real surprise has been conditions on 6 m. Yesterday (July 3-4 UTC), KL7RRC experienced a great 6m opening that resulted in 468 JA QSOs. A few stations were also worked from BY, DU and HL. They will continue to place emphasis on 6m during their remaining time on Adak.
Team leader Yuri N3QQ has indicated that due to the fact this IOTA Expedition emphasized the Kiska portion of the project, anyone who donated to the project wanting a refund, should contact him directly
QSL information can be found on the RRC website: https://na-234.com

M0OXO Bureau Mailing 04th July 2021

M0OXO QSL Bureau Mailing (05/07/2021)
QSL cards have been posted to 85 World Bureaus – Monday 5th July 2021.
This mailing is a joint mailing between M0OXO Charles & M0URX Tim. (Thanks Chris G1VDP)
I would very much appreciate feedback from you when the QSL cards start arriving at World Bureaus or received by hams around the world?
This mailing had been delayed due to Covid-19 restrictions. The cost of air freight for this mailing is considerably higher due to the lack of air freight capacity at this time.
The parcels are sent by Priority Business Mail to get to the Bureaus quickly. Here’s the breakdown;
Total amount of QSL cards dispatched: 23,804
Via M0URX 9,139, Via M0OXO 14,050, Via MD0CCE 615,
Total Weight: 88.328 kgs  £645.93 – £7.31 per kg. (gross weight includes packaging)
Total Shipping Cost £645.93 – £7.31 per kg.
Average postage cost 2.71p per QSL card.
If possible please consider a donation towards out bureau ailing costs. We are trying to keep this service running despite the huge hike in Freight Costs post the Covid Pandemic – Thank you .

M0OXO QSL Bureau Service

A few months ago I considered closing the Bureau option on some of my call signs on OQRS as the demands and costs are getting unsustainable. I actually decided NOT to do that and at this current time, all Bureau cards are now ready to be dispatched in the next couple of weeks.

However, the global pandemic has caused a major restriction on air freight worldwide which has led to enormous increases in costs. For example, 10 small packages to ARRL have increased from £14 in total to £103, while the parcel to Japan JARL from £50 to £160, if you multiply the increases to all 90 IARU Bureau destinations the cost is quite a shock to bear.

I therefore had no choice but to introduce a $0.30c charge on Bureau cards on OQRS to help alleviate losses in my future Bureau mailings.

I appreciate to some, this may not be very popular but let me stress, this is NOT about making money. Applying a small charge/contribution will go a huge way to combat the deficit in Postage Costs to World Bureau’s. Without it the Bureau service will not be viable and will cease.

Thank you for your understanding…

3Y0J Bouvet 2023 Cancelled

To the global DX community.
We regret to inform you of the following news.
The global pandemic has impacted the expedition charter vessel business very hard; this includes the venerable RV Braveheart which has provided outstanding safety and service to many DXpeditions. As you know, we had signed a contract with Braveheart for 3Y0J.
Today, we were informed that Braveheart will be sold. As a result, Nigel Jolly will no longer be associated with the ship, our contract with the ship has been cancelled and our deposit will be refunded. This is a very disappointing development to all involved.
At this time, we are cancelling the 3Y0J Dxpedition. We have ceased accepting donations and we will begin refunding 100% of the donations using the same method they were received, i.e., PayPal, cash or check. This process will take several weeks to sort out, so please be patient.
We wish to thank our team for putting their trust in us. We wish to thank all of the donors and sponsors that gave generously to this project. We will continue to research other ships and possibly find another suitable vessel for a future project.

9N1DX Nepal – First Log received!

With many thanks to Teja 9N1DX in Kathmandu, Nepal, I have just received & uploaded her first log to M0OXO OQRS.
OQRS is now open for 9N1DX however, QSL Cards have to be designed and printed before I can issue any cards so please be patient.
Please also remember to use M0OXO OQRS ‘Missing Call’ service if you don’t find your QSO in the log. This system was introduces as it is the fastest way to get your missing/busted all enquiry resolved and it also saves on a huge email list in my inbox that may take a lot longer to reply to.
Please find her log here;

HK3X Colombia

I have just uploaded a log from Pedro, HK3X in Bogota, Colombia to M0OXO OQRS.
You can obtain a Paper QSL Card from M0OXO for contacts with this station. Please remember I am not the Manager for his DXpeditions but purely for HK3X and HK3JJH.
Qsl Cards are being printed and will be available in a few weeks time although OQRS is now open.

XT2AW Burkina Faso 2021


Harald (DF2WO) will again be qrv from Ouagadougou, Burkina Faso from the 13th June 2021. He will remain there or 3 weeks where as well as Radio, he will be helping local Children with their studies.
Harald will be operation CW, FT8 and also SAT modes. He said SSB will be used but only when conditions allow propagation.
Please QSL via M0OXO OQRS or Direct Post Mail. Bureau QSL Cards are not required and any sent to me via the Bureau will not arrive here.

NL0H Alaska

Henry NL0H is now very active again from St. Lawrence Island / Sivuqaq (IOTA NA-040 ITU Zone 1/CQ Zone 1).His recent antenna upgrades have given him quite a boost on the air and his signals are now being received Worldwide. Henry uses a 2014 Honda Rancher 420 mobile power supply, Yaesu FT-891, and portable super antenna. Usually only on 20, 30 & 40 meters. Also now using a end-fed for radio in the village with decent results thanks to finding a somewhat quiet location although still electrical noise bothering receive.

Henry’s mode of choice is SSB but sadly under current conditions, his 70/100 watts on SSB doesn’t always do the job and he finds himself dropping onto FT8 just to get his rare IOTA and Zone out to the many Chasers who need it.

His antenna modifications have now seen him log VK, ZL, ZS, 3W and many stations in EU including the UK.

Please support Henry by giving him a call when you hear him but again, please be patient, weather conditions in Alaska can be very hard work in the cold weather he is trying is best to accommodate everyone around his busy work schedules.

You can find his Log available to search and request QSL Cards on M0OXO OQRS (Click Logo on the right side of this screen).
