Excerpt: 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.

Total solar eclipses occur about once every 18 months, but they often pass over remote areas such as the ocean. The 21 August eclipse is rare because it will be visible over a heavily populated landmass — the continental United States. About 12 million people live in the path of totality, which stretches from Oregon to South Carolina. Scientists and volunteers plan to take advantage of the situation to gather data and encourage the public to participate in research.
