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.

Half-Saros cycle

A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[2] This lunar eclipse is related to two total solar eclipses of Solar Saros 133.

gollark: CSS grid is very neat and sort of simplifies some positioning things.
