(Eclipse from 2:08pm - 4:35pm)

Caused by the shadow of the Moon lining up to temporarily blot out the Sun, solar eclipses have fascinated people for centuries. While eclipses actually occur somewhat frequently, they are not always viewable, making the times when people do get to see them all the more significant. Philadelphia is expected to see 90% coverage of the Sun, and won’t see an event like this again until 2078, so this is one celestial celebration you won’t want to miss!
