A Total Solar Eclipse over Wyoming

Explanation: Will the sky be clear enough to see the eclipse? This question is already on the minds of many North Americans hoping to see tomorrow's solar eclipse . This question was also on the mind of many people attempting to see the total solar eclipse that crossed North America in August 2017 . Then, the path of total darkness shot across the mainland of the USA from coast to coast , from Oregon to South Carolina -- but, like tomorrow's event, a partial eclipse occurred above most of North America . Unfortunately, in 2017, many locations saw predominantly clouds . One location that did not was a bank of the Green River Lakes , Wyoming . Intermittent clouds were far enough away to allow the center image of the featured composite sequence to be taken, an image that shows the corona of the Sun extending out past the central dark Moon that blocks our familiar Sun . The surrounding images show the partial phase s of the solar eclipse both before and after totality.
