Fred Isberner is a retired healthcare professor in Carbondale, Illinois. But on 21 August, the 69-year-old will be collecting data about the Sun’s superheated outer atmosphere during a total solar eclipse. Isberner is one of thousands of people across the United States who plan to gather data during the event. Their combined efforts will be one of the largest, one-off citizen-science efforts yet.

“It absolutely has the potential to be the biggest,” says Scott McIntosh, director of the National Center for Atmospheric Research’s High Altitude Observatory in Boulder, Colorado.
