Study Total Solar Eclipses With Ham Radio

Ham Radio Science Citizen Investigation (HamSCI) is inviting ham radio operators to make radio contacts during the 2024 total solar eclipse, probing the Earth’s upper atmosphere known as the ionosphere.

Both amateur and professional broadcasters have been sending and receiving radio signals around the Earth for over a century. Such communication is possible due to interactions between our Sun and the ionosphere, the ionized region of the Earth’s atmosphere located roughly 40 to 400 miles overhead. The upcoming total solar eclipse on April 8, 2024, provides a unique opportunity to study these interactions. As HamSCI members transmit, receive, and record signals across the radio spectrum during the eclipse, you will create valuable data to test computer models of the ionosphere.
