HamSCI is seeking volunteers, especially in the Eastern Hemisphere, to help us collect data during the annular solar eclipse on June 21. There will be two data collection periods: A practice/control period on June 14 for participants to get their stations in order, and the main data collection period from June 20-22 UTC. 

Details of the experiment are found here: https://hamsci.org/june-2020-eclipse-festival-frequency-measurement
