Summary
A total lunar eclipse occurred at the Moon’s descending node of orbit on Monday, May 16, 2022,[1] with an umbral magnitude of 1.4155. It was a central lunar eclipse, in which part of the Moon passed through the center of the Earth's shadow. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A total lunar eclipse occurs when the Moon's near side entirely passes into the Earth's umbral shadow. Unlike a solar eclipse, which can only be viewed from a relatively small area of the world, a lunar eclipse may be viewed from anywhere on the night side of Earth. A total lunar eclipse can last up to nearly two hours, while a total solar eclipse lasts only a few minutes at any given place, because the Moon's shadow is smaller. Occurring about 1.3 days after perigee (on May 17, 2022, at 11:30 UTC), the Moon's apparent diameter was larger.[2]

Because this event occurred near lunar perigee, it was referred to some in media coverage as a "super flower blood moon"[Note 1][3][4][5] and elsewhere as a "super blood moon",[6][7][8] a supermoon that coincides with a total lunar eclipse. This was the longest total lunar eclipse visible from nearly all of North America since August 17, 1989 until the next eclipse on November 8.[9][10]
The eclipse was a dark one with the northern limb of the Moon passing through the center of Earth's shadow. This was the first central eclipse of Lunar Saros 131.
This lunar eclipse was the third of an almost tetrad, with the others being on May 26, 2021 (total); November 19, 2021 (partial); and November 8, 2022 (total).
Visibility
editThe eclipse was completely visible over North and South America, seen rising over western North America and the central Pacific Ocean and setting over Europe and Africa.[11]

Eclipse season
editThis eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a fortnight.

Lunar eclipses of 2020–2023
editThis eclipse is a member of a semester series. An eclipse in a semester series of lunar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit.[13]
The penumbral lunar eclipses on January 10, 2020 and July 5, 2020 occur in the previous lunar year eclipse set.

Saros 131
editThis eclipse is a part of Saros series 131, repeating every 18 years, 11 days, and containing 72 events. The series started with a penumbral lunar eclipse on May 10, 1427. It contains partial eclipses from July 25, 1553 through March 22, 1932; total eclipses from April 2, 1950 through September 3, 2202; and a second set of partial eclipses from September 13, 2220 through April 9, 2563. The series ends at member 72 as a penumbral eclipse on July 7, 2707.
The longest duration of totality will be produced by member 38 at 100 minutes, 36 seconds on June 28, 2094. All eclipses in this series occur at the Moon’s descending node of orbit.[14]

 The greatest eclipse of the series will occur on 2094 Jun 28, lasting 100 minutes, 36 seconds.[15] |

Eclipses are tabulated in three columns; every third eclipse in the same column is one exeligmos apart, so they all cast shadows over approximately the same parts of the Earth.

Metonic series
editThis eclipse is the third of four Metonic cycle lunar eclipses on the same date, 15–16 May, each separated by 19 years.
The Moon's path through the Earth's shadow near its descending node progresses southward through each sequential eclipse. The second and third are total eclipses.
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.

Half-Saros cycle
editA lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[16] This lunar eclipse is related to two annular solar eclipses of Solar Saros 138.
