2017 Total Solar Eclipse

Map of US Eclipses from 2017-2052

On 21 August 2017, a total solar eclipse caused the shadow of the moon to traverse the United States from Oregon to South Carolina in just over 90 minutes. Although the ionospheric effects of solar eclipses have been studied for over 50 years, many unanswered questions remain. HamSCI invited amateur radio operators to participate in a large-scale experiment which characterized the ionospheric response to the total solar eclipse and targeted open science questions.

Hundreds of ham radio operators helped out by getting on the air with the Solar Eclipse QSO Party, a contest-like operating event designed to generate data for studying the eclipse. Other HamSCI experiments included making HF Frequency Measurements, recording HF spectra, setting up a Reverse Beacon Network Receiver, particpating in VLF/LF receiving experiements, and listening to AM broadcast stations. See our Eclipse Get Involved for more information.

Are you curious about how prior total solar eclipses affected the ionosphere? Read about radio experiements during the 1999 United Kingdom Total Solar Eclipse coordinated by the Rutherford Appleton Laboratory.

Our sense of sound can be a powerful tool in exploring and analysing data collected from satellites. But what is the best way to make this data audible? Space science researchers at Imperial College London are asking for input from communities with relevant expertise (including Audio, Citizen Science, Music, Public Engagement, and Science Communication) to help us choose the best method of making Ultra-Low Frequency waves around the Earth audible. Fill out our quick survey telling us which you think sounds best. It shouldn’t take more than 10 minutes. Your valuable feedback and recommendations will help space scientists around the world to improve science communication, public engagement, and citizen science.

If you would like further information please contact Dr Martin Archer, Stephen Hawking Fellow in Space Physics at Imperial College London via m.archer10@imperial.ac.uk. Thank you for your help!

The 40th annual ARRL and TAPR Digital Communications Conference (DCC) will take place September 17–18, 2021. Due to the coronavirus pandemic, this year’s conference will be held online. Registered DCC attendees participating via Zoom will be able to interact with presenters and other attendees via a chat room as well as raise a virtual hand to ask questions. Click here to register (you don’t need a Zoom account to register). Non-registered DCC attendees can watch the live stream for free on YouTube and can chat and ask questions via the moderator monitoring the channel. No registration is required for YouTube access (the YouTube URL will be announced and posted on this webpage preceding the DCC). DCC registration is free for TAPR members and $30 for non-members. Members receive a 100% discount at checkout. Click here to register. Non-members who would like to join TAPR and receive the free DCC pass can simply add TAPR membership and DCC registration to their shopping carts. After checkout, they will receive the free DCC pass when their membership is processed.

Call for Papers and Speakers: Technical papers are being solicited for presentation. Papers will also be published in the Conference Proceedings. Authors do not need to participate in the conference to have their papers included in the Proceedings. The submission deadline is August 15, 2020. Submit papers via email to Maty Weinberg, KB1EIB, maty@arrl.org. Papers will be published exactly as submitted, and authors will retain all rights.

HamSCI's Kristina Collins KD8OXT, a PhD student a Case Western Reserve University, was interviewed by Steve Ford WB8IMY in the March 11, 2021 epsiode of ARRL's Ecletic Tech podcast. In the podcast, Kristina talks about the upcoming 2021 HamSCI Workshop, the Grape Personal Space Weather Station, and the Festivals of Frequency Measurement. The Festivals of Frequency Measurement are large-scale experiments to observe ionospheric and propagation variablity by measuring small Doppler shifts in signals received from standards stations such as NIST's WWV. Kristina's recently published a feature article on the HamSCI work in the American Geophysical Union's EOS magazine and initial results of the 2019 WWV Centenial Festival of Frequency Measurement in IEEE Geoscience and Remote Sensing Letters. Great job, Kristina!
