The solar eclipse of August 21, 2017, was a total solar eclipse visible within a band that spanned the entire contiguous United States, passing from the Pacific to the Atlantic coasts. As a partial solar eclipse, it was visible on land from Nunavut in northern Canada to as far south as northern South America. In Africa and northwestern Europe, it was partially visible in the late evening. In Asia, it was visible only at the eastern extremity, the Chukchi Peninsula. Prior to this event, no solar eclipse had been visible across the entire contiguous United States since June 8, 1918; not since the February 1979 eclipse had a total eclipse been visible from anywhere in the mainland United States. The path of totality, up to about 70 miles (110 km) wide, touched 14 states, while the rest of the U.S. experienced a partial eclipse.
This picture shows the solar eclipse during totality as seen from outside Crowheart, Wyoming. The image is a composite of multiple exposures, bracketed to show both the Sun's corona and the surface features of the new moon itself, illuminated by earthshine. A few solar prominences are visible around the lunar limb.Photograph credit: Michael S. Adler
