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.
