By now I'm sure you've heard ...
Two weeks from today on 21 August 2017 there will be a total eclipse of the sun across the United States. The moon will pass between Earth and Sun, casting its shadow on our continent.
In a narrow band 70 miles wide, from Oregon to South Carolina, the sun will disappear completely for about two minutes. Folks eager to witness the total eclipse have made plans to visit sites in its path including Nashville, TN and Charleston, SC.
Pittsburgh will see only a partial eclipse but there will be plenty to watch. The moon will move across the sun from 1:10p to 3:55p with maximum coverage resembling the crescent below at 2:35p. Don't watch without special glasses and, for your scope and camera, special filters! See below.
