Relations to other lunar eclipses

Eclipses of 1989

Lunar year series

This eclipse is the second of four lunar year eclipses occurring at the moon's ascending node.

The lunar year series repeats after 12 lunations or 354 days (Shifting back about 10 days in sequential years). Because of the date shift, the Earth's shadow will be about 11 degrees west in sequential events.

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, 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 series

It is the third of five Metonic cycle eclipses, each being 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.

Tritos series

The tritos series repeats 31 days short of 11 years at alternating nodes. Sequential events have incremental Saros cycle indices.

This series produces 23 total eclipses between June 22, 1880 and August 9, 2120.
