Sun Unleashes Monster Solar Flare, Strongest in a Decade

By Sarah Lewin, Space.com Associate Editor


This article was updated at 5:44 p.m. EDT to indicate that a coronal mass ejection was observed coming from the site of the solar flare.

Early this morning (Sept. 6), the sun released two powerful solar flares — the second was the most powerful in more than a decade.

At 5:10 a.m. EDT (0910 GMT), an X-class solar flare — the most powerful sun-storm category — blasted from a large sunspot on the sun’s surface. That flare was the strongest since 2015, at X2.2, but it was dwarfed just 3 hours later, at 8:02 a.m. EDT (1202 GMT), by an X9.3 flare, according to the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center (SWPC). The last X9 flare occurred in 2006 (coming in at X9.0).

ARISS SSTV (Update)

In commemoration of the 20th anniversary, the ARISS team is planning to transmit a set of 12 SSTV images that capture the accomplishments of ARISS over that time. While still to be scheduled, they anticipate the SSTV operation to occur around the weekend of July 15. This is now scheduled for Thursday, July 20 until Monday July 24 1800 UTC.
(I record the received audio and then later decode it using a program like MMSSTV)

An SSTV image sent from the ISS on Sunday 7/23/2017 around 10:00 PM Pacific. This was a visible pass of the ISS so it was easily tracked with the naked eye, making it easy to aim the antenna.

Amateur Radio Payloads Share Ride into Space with Soil Moisture Monitoring Satellite

Four NASA Educational Launch of Nanosatellites (ELaNA-X) CubeSats carrying Amateur Radio payloads launched successfully January 31 from California’s Vandenberg Air Force Base. The primary payload for the Delta II launcher was the Soil Moisture Active Passive (SMAP) satellite. SMAP’s onboard radar will share Amateur Radio spectrum at 1.26 GHz. Amateur Radio is secondary on the 23 centimeter band, which covers 1240 to 1300 MHz.

Two Astronauts Get Their Ham Ticket

Even though they aren’t scheduled to go to the International Space Station (ISS) until 2013, two astronauts — Chris Cassidy and Luca Parmitano — are now licensed amateurs. Cassidy, who received the call sign KF5KDR, is scheduled to head to the ISS in March 2013 as part of Expedition 35. Parmitano, who is KF5KDP, goes up three months later in May, as part of Expedition 36.

Amateur Radio Operators remembered for volunteering during Columbia Disaster

NACOGDOCHES, TX (KTRE) – When the Space Shuttle Columbia disintegrated over East Texas in 2003, hundreds came forward to help with recovery efforts.

Some of those volunteers were ham radio operators who set up communication with law enforcement across East Texas. Saturday, the Nacogdoches Amateur Radio Club held a special event to say thank you.

NANOSAIL-D EJECTS: NASA SEEKS AMATEUR RADIO OPERATORS’ AID TO LISTEN FOR BEACON SIGNAL

HUNTSVILLE, Ala. — Wednesday, Jan. 19 at 11:30 a.m. EST, engineers at Marshall Space Flight Center in Huntsville, Ala., confirmed that the NanoSail-D nanosatellite ejected from Fast Affordable Scientific and Technology Satellite, FASTSAT. The ejection event occurred spontaneously and was identified this morning when engineers at the center analyzed onboard FASTSAT telemetry. The ejection of NanoSail-D also has been confirmed by ground-based satellite tracking assets.
