Lunar year series

Saros series

This lunar eclipse is part of series 133 of the Saros cycle, which repeats every 18 years and 11 days. Series 133 runs from the year 1557 until 2819. The previous eclipse of this series occurred on 21 February 2008 and the next will occur on 13 March 2044.

It is the 7th of 21 total lunar eclipses in series 133. The first was on 28 December 1917. The last (21st) will be on 3 August 2278. The longest two occurrences of this series (14th and 15th) will last for a total of 1 hour and 42 minutes on 18 May 2152 and 30 May 2170. Solar saros 140 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series.

Metonic cycle (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 be in nearly the same location relative to the background stars.

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 35.

Half-Saros cycle

A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).^[1] This lunar eclipse is related to two annular solar eclipses of Solar Saros 140.
