Total Eclipse of the Sun, USA — August 21, 2017

See also the basic data page for this eclipse.

On the 21st of August 2017, the U.S.A. will be treated to a spectacular total solar eclipse which will cross the width of the US mainland from Oregon to South Carolina from 17:15:58–18:49:12 UT. This rare and spectacular event will be seen from a path of totality over 100 km (62.1 miles) wide, and will give watchers close to the centreline an amazing 2 minutes or more of total eclipse. A partial eclipse will be visible from the whole of North America and Hawaii, as well as northern South America.

Safety First!
A total solar eclipse is not safe to look at with the naked eye except during the few brief seconds or minutes of total eclipse, when the Sun itself is completely obscured by the Moon. At all other times, and if you are outside of the path of the total eclipse, you must use proper solar viewing protection. For more information, see our eye safety page.

This incredible eclipse is a wonderful event, but in fact the USA is blessed with total eclipses this century, seeing four total solar eclipses up to 2052, and 11 in the century. This is explained more on the USA Eclipse Bonanza page.
