Solar Eclipse 2017

August 21, 2017

About The Eclipse:
A total solar eclipse occurs when the moon passes between the sun and Earth and blocks all or part of the sun. From start to finish this can take up to three hours and can be viewed at various locations. Along the path of this eclipse and from any given location the longest the moon will completely block the sun will be approximately two minutes and 40 seconds. A total solar eclipse doesn’t happen often, the last time the contiguous U.S. saw one was in 1979.

Anyone in North America will be able to see a partial eclipse. Visit to see, based on your zip code, the time the eclipse will happen and how much of the sun will be eclipsed in your area. In order to see a total eclipse, when the moon fully covers the sun for a short few minutes, you must be in the path of totality, which is a relatively thin ribbon, around 70 miles wide, that will cross the U.S. from West to East. The small path of totality will move across sections of 14 states.
