The total eclipse begins at about 10:15am Pacific daylight time on the westernmost Oregon beach within the dark shadow of the Moon, and ends at about 2:48pm Eastern daylight time on the easternmost cape in South Carolina.  It will take about 90 minutes to cross the U.S. and the shadow will move at an average speed of 1450 mph, faster than commercial jets travel.  If you are wondering how 10:15am to 2:48 pm could be a total time of only about 90 minutes, keep in mind that the eclipse will move across the four time zones of the U.S.  Be prepared, come to the Clearwater Public Library for the Cosmosphere presentation on Wednesday, August 2nd at 6:00PM.  All that attend will receive a pair of NASA approved Solar eclipse glasses and may even win a door prize!  Door prizes include a Yardstick eclipse set and tickets to the Lake Afton Observatory.
