Solar Saros 133 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series. First penumbral lunar eclipse: 18 July 1228 First partial lunar eclipse: 24 March 1625 First total lunar eclipse: 19 June 1769 First central lunar eclipse: 11 July 1805 Greatest eclipse of the lunar saros 126: 13 August 1859, lasting 106 minutes.

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.
