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.

Inex series

The inex series repeats eclipses 20 days short of 29 years, repeating on average every 10571.95 days. This period is equal to 358 lunations (synodic months) and 388.5 draconic months. Saros series increment by one on successive Inex events and repeat at alternate ascending and descending lunar nodes.

This period is 383.6734 anomalistic months (the period of the Moon's elliptical orbital precession). Despite the average 0.05 time-of-day shift between subsequent events, the variation of the Moon in its elliptical orbit at each event causes the actual eclipse time to vary significantly. It is a part of Lunar Inex series 40.

All events in this series shown (from 1000 to 2500 and beyond) are central total lunar eclipses.

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.

gollark: ... why would they do it *that* way? Does it not even say something like "would you like to allow this device access to your account: yes/no"?
gollark: I think they have *some* vague idea of economics and history, or have advisors who do, but don't care and do the good-sounding-if-you-don't-think-about-it-much thing.
gollark: I mean, if not technically FTL, they're a thing people think of when they think "FTL travel".
gollark: "Not FTL" how? I mean, they get you from A to B faster than you could with sublight travel.
gollark: Huh? It has FTL. Which is apparently... possible...
