Saros series

Lunar saros series 128, repeating every 18 years and 11 days, has a total of 71 lunar eclipse events including 57 umbral eclipses (42 partial lunar eclipses and 15 total lunar eclipses). Solar Saros 135 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series.

Greatest First

The greatest eclipse of the series occurred on 1953 Jul 26, lasting 108 minutes.[1]		 Penumbral Partial Total Central

Lunar Saros 128 contains 15 total lunar eclipses between 1845 and 2097 (in years 1845, 1863, 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.

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 annular solar eclipses of Solar Saros 135.
