Saros series
[edit]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
[edit]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.
