'For the first time in 99 years, a total solar eclipse will be visible on Aug. 21 to spectators across the contiguous United States. As the moon moves between the Earth and the sun, the 68-mile-wide shadow it casts (called the “umbra”) will sweep across the Earth’s surface, moving around 1,200 mph along a path stretching from Oregon to South Carolina.People in the center of the shadow’s path will be plunged into darkness for no more than about two and a half minutes. The temperature may drop 20 or so degrees, depending on the location. The wind may suddenly change direction. Stars, planets and the moon will become visible. Some animals might prepare for bed. (Probably not cows, though. A 1999 study found eclipses have “little, if any effect” on the ruminants.) '
