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
