On Monday, August 21 a total solar eclipse will darken the skies across the continental United States from Oregon to South Carolina. It's the first eclipse that will be seen from coast to coast in 99 years. The “Path of Totality,” where the sun appears to be completely covered, will be about 70 miles wide. Outside the Path of Totality, many of us will see a partial solar eclipse with only a portion of the sun covered by the moon. Here in Rochester and the Finger Lakes, we will see approximately 70% coverage of the sun. The partial eclipse will last about 2½ hours, beginning at 1:14 pm and ending at 3:52 pm. The maximum coverage will be at 2:35 pm.
