Check out some of the observations your fellow astronomers made on iNaturalist!

The "Great American Eclipse" takes place on Monday, August 21, when the shadow of the Moon sweeps coast-to-coast across the United States. This is the first time since 1979 that a total eclipse will be visible from the continental United States—and the next time won't be until 2024.

For the roughly 12 million people who live along the narrow path of the Moon's shadow, or "totality," the entire Sun will be blocked from view. San Francisco isn't in the totality's path, but it will still be an incredible show: 80% of the Sun's diameter will be covered by the Moon between 9:01 am and 11:37 am.

Read on for a variety of ways to experience—and participate in—this incredible astronomical event.

Please note: Museum admission required for eclipse events at the Academy.
