2017 Total Solar Eclipse

Map of US Eclipses from 2017-2052

On 21 August 2017, a total solar eclipse will cause 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 is inviting amateur radio operators to participate in a large-scale experiment which will characterize the ionospheric response to the total solar eclipse and target open science questions.

Would you like to participate? Help 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 ways to get involved include 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.

I’ve received community feedback that people want more guidance on running JT-modes during the SEQP. As a result, we have revised rules. There are some also changes to provide guidance in other areas as well, including using SNRs or RSQs for digital mode signal reports. None of these changes affect the scoring procedure, but hopefully they will make the operating procedures more clear. Also, I’ve been made aware that there is currently a bug in N1MM+ that prevents SEQP signal reports from being saved to ECLIPSE Cabrillo files.

The real time packet communications system APRS will be used during the day of the eclipse as a national communications network for those involved in ham radio and eclipse observations to be able to track each other and see where other nearby ham observers are located.  Imagine the APRS map that day showing a clustering of mobile and portable positions all along the totality line.  Please use the station symbol SUNNY for this event so these stations will stand out among all others on the national tracking page http://aprs.fi.

The 2017 Great American Eclipse and the HamSCI Solar Eclipse QSO Party on August 21, 2017 are now just weeks away! This is a great oportunity to both enjoy ham radio and help scientists better understand how the ionosphere works. Are you ready? HamSCI member Ward Silver, N0AX is! He is shown here modeling his new SEQP tank-top and mug. We now have a variety of HamSCI and SEQP T-Shirts and mugs availble through the HamSCI RedBubble store.
