Get ready for the great American eclipse of 2017 with expert advice from "Mr. Eclipse", Fred Espenak.

On August 21, 2017, a total eclipse of the Sun will be visible from the contiguous United States for the first time since 1979. The track of the Moon’s shadow cuts diagonally across the nation from Oregon to South Carolina. Inside the 68-mile-wide path of totality, the Moon will completely cover the Sun as the landscape is plunged into an eerie twilight, and the Sun’s glorious corona is revealed for over 2 minutes.

Espenak presents a detailed preview of this exciting event with maps, photos and weather prospects along the eclipse path based on his recent book on the same subject. He will also share some of his eclipse experiences with us through photos and video. Find out what it’s like to stand in the Moon’s shadow and get ready for 2017.
