Metonic series[]

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