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.

Saros series

Lunar Saros series 126, repeating every 18 years and 11 days, has a total of 70 lunar eclipse events including 14 total lunar eclipses. Solar Saros 133 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series.

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 total solar eclipses of Solar Saros 133.

gollark: AI is simply not good enough yet. The only solution is me as supreme eternal world dictator for life.
gollark: I see.
gollark: Maybe the design was bad or maybe people messed up the execution. But a good design factors in some degree of problems in the execution side.
gollark: The existence of working ways to modify them as needed isn't guaranteed.
