EclipseMob has collected nearly 500 recordings from locations across the United States. We will post results here as we analyze the data that has been collected. We would like to thank you using the words of the scientists who led the historic first attempt at a crowdsourced eclipse measurement, 92 years ago:


"We are deeply grateful to all of [our] collaborators. They have sent us data of great value. We hope that the knowledge of a good job well done will prove to them a satisfactory reward for their effort and time."

-Scientific American Eclipse Party, "The Effects of the Eclipse on Radio," Scientific American, April 1925

EclipseMob Participants map

EclipseMob is a collaborative effort to conduct a crowdsourced measurement of low-frequency radio wave propagation during the August 2017 solar eclipse.

Our guides will help you build your own radio receiver system!

Find out more about how eclipses happen, radio waves work, and the ionosphere behaves! 

(For Educators: Activities & lesson plans can be found here)

Connect with other participants and get tips on how to communicate your results!

Take part in a nation-wide experiment! Explore ways to experiment with your receiver after the eclipse and/or reconfigure your receiver system parts to try out your own investigations.

Find the latest updates on upcoming webinars, Q & A events, experiment logistics, etc.
