Saros series edit

This eclipse is part of Saros cycle 146.

Metonic series edit

This eclipse is the last of four Metonic cycle lunar eclipses on the same date, 28–29 October, 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.

Metonic events: May 4 and October 28
