Saros series

Lunar Saros 111, repeating every 18 years and 11 days, has a total of 71 lunar eclipse events including 11 total lunar eclipses. The first total lunar eclipse of this series was on April 19, 1353, and last was on August 4, 1533. The longest occurrence of this series was on June 12, 1443 when the totality lasted 106 minutes.

Metonic series

The Metonic cycle repeats nearly exactly every 19 years and represents a Saros cycle plus one lunar year. Because it occurs on the same calendar date, the earth's shadow will in nearly the same location relative to the background stars.

Half-Saros cycle

A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[2] This lunar eclipse is related to two solar eclipses of Solar Saros 118.

April 30, 1957 May 11, 1975
