The HamSCI Festivals of Eclipse Ionospheric Science will occur October 14, 2023 and April 8, 2024 during spectacular North American solar eclipses.

The Festivals will consist of multiple events, each with a goal of increasing our understanding of sun-ionosphere-earth relationships.

Participants will include volunteer amateur radio operators, short wave listeners and science researchers from multiple US universities.

♦ HamSCI FoEIS Contests (Non-WARC Bands, 6-160 meters)

• The Solar Eclipse QSO Party (SEQP) using CW, FT4/8, SSB and other digital modes
• The Gladstone Signal Spotting Challenge (GSSC) using CW, WSPR and FST4W modes
• The HamSCI FoEIS Contest Info Page has all of the details

♦ HamSCI FoEIS Research Events (40, 75 and 160 meters)

• TDOA (Time Delay of Arrival) Event - The Use of Time Delay of Arrival (TDOA) Measurements to Profile Ionospheric Layer Height Changes During Solar Eclipses

♦ Grape Personal Space Weather Station (Monitoring WWV, WWVH, CHU)

• Using the Grape 1 and Grape 2 Low-IF receivers to measure Doppler Effects on the Reception of WWV and CHU (this is a long term experiment - monitoring and data gathering has research value on a 24/7/365 basis - beginning anytime before and continuing long after the eclipses)
