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. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometers wide.
This eclipse is the 22nd of the 77 members of Saros series 145, the one that also produced the solar eclipse of August 11, 1999. Members of this series are increasing in duration. The longest eclipse in this series will occur on June 25, 2522 and last for 7 minutes and 12 seconds.
The eclipse will have a magnitude of 1.0306 and will be visible from a narrow corridor through the United States. The longest duration of totality will be 2 minutes 41.6 seconds at 37°35′0″N 89°7′0″W / 37.58333°N 89.11667°W in Shawnee National Forest just south of Carbondale, Illinois and the greatest extent will be at 36°58′0″N 87°40′18″W / 36.96667°N 87.67167°W near Cerulean, Kentucky between Hopkinsville and Princeton, Kentucky. It will be the first total solar eclipse visible from the southeastern United States since the solar eclipse of March 7, 1970.
