Relation to other eclipses[edit]

Lunar year series[edit]

It is the last of four lunar year cycles, repeating every 354 days.

Metonic series[edit]

This eclipse is the last of four Metonic cycle lunar eclipses on the same date, October 17–18, 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[edit]

A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[1] This lunar eclipse is related to two partial solar eclipses of Solar Saros 153.
