A U.S. Flag in downtown Washington flies in front of the moon during a lunar eclipse, Sunday, Jan. 20, 2019. The entire eclipse will exceed three hours. Totality - when the moon's completely bathed in Earth's shadow - will last an hour. Expect the eclipsed, or blood moon, to turn red from sunlight scattering off Earth's atmosphere. (AP Photo/J.
