During the total solar eclipse on Aug. 21, 2017, the moon will completely cover the disk of the sun from Lincoln Beach, Oregon to Charleston, South Carolina. This will be the first total solar eclipse in the continental U.S. in 38 years. The last one occurred February 26, 1979.
This solar eclipse will occur as the moon passes between the sun and Earth and blocks all or part of the sun for up to about three hours, from beginning to end, as viewed from a given location. For this eclipse, the longest period when the moon completely blocks the sun from any given location along the path will be about two minutes and 40 seconds.
Grants Pass will experience a roughly 90% partial eclipse around 10:15 am. Check out this simulator to see how the eclipse will look in different cities.
