This lunar eclipse is first of a tetrad, four total lunar eclipses in series. The following tetrad is in 1985 and 1986, starting with a May 1985 lunar eclipse.

The Surveyor 3 probe landed on the moon during this eclipse.[2]

Tritos series

The tritos series repeats 31 days short of 11 years at alternating nodes. Sequential events have incremental Saros cycle indices.

This series produces 20 total eclipses between April 24, 1967 and August 11, 2185, only being partial on November 19, 2021.

Metonic series

This eclipse is the third of four Metonic cycle lunar eclipses on the same date, April 23–24, each separated by 19 years:

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).[3] This lunar eclipse is related to two annular solar eclipses of Solar Saros 128.
