Lunar Saros 128 contains 15 total lunar eclipses between 1845 and 2097 (in years 1845, 1867, 1881, 1899, 1917, 1935, 1953, 1971, 1989, 2007, 2025, 2043, 2061, 2079 and 2097). Solar Saros 135 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series.

Metonic cycle (19 years)

This eclipse is the second of four Metonic cycle lunar eclipses on the same date, September 7, 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.
