Relations to other lunar eclipses

Lunar year series

This eclipse is the second of four lunar year eclipses occurring at the moon's ascending node.

The lunar year series repeats after 12 lunations or 354 days (Shifting back about 10 days in sequential years). Because of the date shift, the Earth's shadow will be about 11 degrees west in sequential events.

Lunar eclipse series sets from 1988-1991

Metonic series

It is the third of five Metonic cycle eclipses, each being 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.

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

This series produces 23 total eclipses between June 22, 1880 and August 9, 2120.
