Solar eclipse of August 21, 2017. A total solar eclipse will take place on Monday, August 21, 2017. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth.
The August 2017 eclipse will be the first with a path of totality crossing the USA's Pacific coast and Atlantic coast since 1918. Also, its path of totality makes landfall exclusively within the United States, making it the first such eclipse since the country's independence in 1776. (The path of totality of the eclipse of June 13, 1257, was the last to make landfall exclusively on lands currently part of the USA.)
