When & Where

Eclipse PosterOn Monday, August 21, 2017, all of North America will be treated to an eclipse of the sun. To see a total eclipse, where the moon fully covers the sun for a short few minutes, you must be in the path of totality. The path of totality is a relatively thin ribbon, around 70 miles wide, that will cross the U.S. from West to East.  The first point of contact will be at Lincoln Beach, Oregon at 9:05 a.m. PDT. Totality begins there at 10:16 a.m. PDT.  Over the next hour and a half, it will cross through Oregon, Idaho, Wyoming, Montana, Nebraska, Iowa, Kansas, Missouri, Illinois, Kentucky, Tennessee, Georgia, and North and South Carolina.  The total eclipse will end near Charleston, South Carolina at 2:48 p.m. EDT.  From there the lunar shadow leaves the United States at 4:09 EDT.

 

This celestial event is a solar eclipse in which 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.  The last time the contiguous U.S. saw a total eclipse was in 1979.

Below are some maps and diagrams that give you an idea of the eclipse’s time and place, as well as where the sun will be when the eclipse happens.
