Solar Eclipse QSO Party 2017


On August 21, 2017, a total solar eclipse caused the shadow of the moon to traverse the U.S. from Oregon to South Carolina in just over 90 minutes, causing dramatic changes in both the ionosphere and HF propagation. The Solar Eclipse QSO Party (SEQP) was a HamSCI-ARRL sponsored operating event to generate data to study ionospheric changes during the eclipse. Not a ham radio operator yet?

Science Results

  • Initial SEQP Science Results using RBN data have been published by Frissell et al. (2018) in Geophysical Research Letters. The figures below are excerpts from the paper, showing RBN spot coverage during the SEQP and propapagtion effects relative to maximum eclipse time on the 1.8, 3.5, 7, and 14 MHz bands.

2017 Hamvention SEQP Presentation


The SEQP was coordinated by Nathaniel Frissell, W2NAF, at the New Jersey Institute for Technology Center for Solar Terrestrial Research (NJIT-CSTR) with support from the National Science Foundation grant AGS-1552188/479505-19C75 and the NJIT-CSTR. Thanks to the many collaborators, including those at Virginia Tech, Montclair State University, the MIT Haystack Observatory, the Johns Hopkins University Applied Physics Laboratory. Special thanks to the American Radio Relay League for publicizing the SEQP and the Reverse Beacon Network and PSKReporter for extra support in data collection.
