The Earth will pass between the Moon and Sun from 09:45 to 12:52 UTC on May 26, 2021, creating a total lunar eclipse -- visible from eastern Asia, Australia, the Pacific, and the Americas. The total eclipse will last from 11:12 until 11:26 -- with the greatest eclipse at 11:18 UTC. This is 0.4 days after the Moon reaches perigee. During this eclipse, the Moon will be in the constellation of Scorpius. The synodic month in which the eclipse takes place has Brown Lunation Number of 1217, according to eclipse specialist Fred Espenak. The eclipse belongs to the Saros 121 and is number 55 of 82 eclipses in the series. All eclipses in this series occur at the Moon’s descending node. The Moon moves northward with respect to the node with each succeeding eclipse in the series and gamma increases. "This is a very shallow total eclipse," Espenak said. "It has an umbral eclipse magnitude of only 1.0095 and a duration of totality lasting 14.5 minutes. Gamma has a value of 0.4774." The eclipse is followed two weeks later by an annular solar eclipse on June 10, 2021.
