The Great American Eclipse: Virginia Tech researcher grapples with a year’s worth of data

Stationed in an empty field at Shaw Air Force Base near Sumter, South Carolina, Virginia Tech electrical engineering professor Greg Earle and his team waited for the total solar eclipse of 2017. Rather than traveling toward the path of totality to see one of “nature’s most awe-inspiring sights,” Earle prepared to put his three-year-old hypothesis […]

via the ARRL: Space Weather Prediction Center Says Solar Phenomena May Continue

The Space Weather Prediction Center (SWPC) said today that G4 (Severe) geomagnetic storm levels were observed at 2350 UTC on September 7 and again at 0151 UTC and 1304 UTC on September 8, due to the effects of a coronal mass ejection (CME). A G3 (Strong) or greater warning was in effect until 1500 UTC […]

via the ARRL: Solar Flares Spark Radio Blackouts, Auroral Displays Possible

NOAA’s Space Weather Prediction Center (SWPC) has issued a strong (G3) geomagnetic storm watch for September 7 through September 9. The SWPC said the watch for September 7 remains in effect due to the arrival of a coronal mass ejection (CME) and the effects of a CME on September 4. “Additionally, a G3 watch is […]

More Professional and Citizen Research Suggests Eclipse Briefly Affected HF Propagation

Both professional and citizen scientists conducted formal and informal investigations into the effect of the August 21 solar eclipse on HF radio propagation. Nathaniel Frissell, W2NAF, of HamSCI, has said it will take some time to get a more scientific analysis of data compiled during the Solar Eclipse QSO Party. Frissell and others are investigating […]

Solar Eclipse QSO Party a Hit, Science Conclusions Await Additional Analysis

The 2017 Solar Eclipse QSO Party (SEQP) is history, and, while logs are still coming in, the preliminary participation numbers look good, according to Nathaniel Frissell, W2NAF, of HamSCI. “Although the final numbers are not yet in, preliminary reports show that over 670,000 spots were detected by the Reverse Beacon Network (RBN), and over 542,000 […]

Solar Eclipse QSO Party Signup So Far Has Attracted More Than 250 Eclipse Enthusiasts

The Solar Eclipse QSO Party (SEQP) now is just a week away — Monday, August 21 — and more than 250 radio amateurs in the US and elsewhere already have signed up to take part. The SEQP is a special operating event organized by the Ham Radio Science Citizen Investigation (HamSCI), led by Nathaniel Frissell, […]

via the ARRL: Amateur Radio Communication Resources to be Available during Eclipse Day

ARRL, the American Red Cross, and The Salvation Army Team Emergency Radio Network (SATERN) will partner on Monday, August 21, to provide a nationwide communication link for local and regional American Red Cross units should a communications failure occur during the solar eclipse. “Concern has been expressed by public safety, emergency management, and others that […]

via HACKADAY: Crowdsourcing The Study Of An Eclipse’s Effect On Radio Propagation

If you are an American, you’ll probably now find yourself in one of three camps. People who are going to see the upcoming solar eclipse that will traverse your continent, people who aren’t going to see the eclipse, and people who wish everyone would just stop going on incessantly about the damn eclipse. Whichever of […]

Will you be able to call 911 during the solar eclipse? Emergency managers prepare for cell towers to jam (Oregon)

When an expected 1 million people converge on Oregon for next month’s solar eclipse — what many call the most dramatic celestial event viewable from Earth — they will be calling, texting, tweeting and posting selfies of their experience to Snapchat and Instagram. Perhaps the only people not smiling at the thought of this solar […]

Arecibo Observatory Ionospheric Heating Campaign Under Way

Arecibo Observatory in Puerto Rico is conducting an ionospheric heating campaign July 24-31, using HF. “The new Arecibo ionosphere HF heater nominally transmits 600 kW net power and has a unique Cassegrain dual-array antenna design that increases gain of three crossed dipoles for each band, using the signature 1000-foot spherical dish reflector,” explained Chris Fallen, […]

Virginia Tech Expert to Study August Eclipse for Impacts on Radar, Ham Radio, GPS

August 21 is a once-in-a-lifetime opportunity for many in the U.S. to see a total eclipse — but for scientists and engineers, it’s a chance to conduct research on systems we rely on for communication, safety and even transportation. A Virginia Tech expert, backed by research funding from NASA and the National Science foundation, will […]

Many Special Events Will Be on the Air to Mark the Total Solar Eclipse in August

Radio amateurs from several states will gather in southern Illinois on August 17-21 to operate special event station W9E, leading up to and during the 2017 solar eclipse on August 21. W9E will operate from Marion, Illinois. “This will be the first total eclipse on American soil since 1991, the first on the mainland United […]

via the RSGB: Asteroid named after radio amateur

The International Astronomical Union has named a celestial body after a radio amateur. Space physicist and radio amateur Asta Pellinen Wannberg, SM3UHV, is a professor at the Department of Physics at Umea University. She has made a ground-breaking effort to use scattering radar when studying meteors that are activated when small particles penetrate the atmosphere. […]

Totality-minus-6 months: Ten ways to get fired up for an all-American solar eclipse

Six months from today, millions of Americans will watch the sun darken during a rare coast-to-coast eclipse – and it’s not too early to get into the spirit of totality. It’s definitely not too early to figure out where you’re going to be: Hotel rooms in the track of the total solar eclipse for the […]
