May 2022 lunar eclipse

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. 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

edit

The 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

edit

This 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.

Saros 131

edit

Lunar Saros series 131, has 72 lunar eclipses. Solar Saros 138 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series.

This eclipse series began in AD 1427 with a partial eclipse at the southern edge of the Earth's shadow when the Moon was close to its descending node. Each successive Saros cycle, the Moon's orbital path is shifted northward with respect to the Earth's shadow, with the first total eclipse occurring in 1950. For the following 252 years, total eclipses occur, with the central eclipse being predicted to occur in 2078. The first partial eclipse after this is predicted to occur in the year 2220, and the final partial eclipse of the series will occur in 2707. The total lifetime of the lunar Saros series 131 is 1280 years. Solar Saros 138 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series.

Because of the ⅓ fraction of days in a Saros cycle, the visibility of each eclipse will differ for an observer at a given fixed locale. For the lunar Saros series 131, the first total eclipse of 1950 had its best visibility for viewers in Eastern Europe and the Middle East because mid-eclipse was at 20:44 UT. The following eclipse in the series occurred approximately 8 hours later in the day with mid-eclipse at 4:47 UT, and was best seen from North America and South America. The third total eclipse occurred approximately 8 hours later in the day than the second eclipse with mid-eclipse at 12:43 UT, and had its best visibility for viewers in the Western Pacific, East Asia, Australia and New Zealand. This cycle of visibility repeats from the initiation to termination of the series, with minor variations. Solar Saros 138 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series.

Lunar Saros series 131, repeating every 18 years and 11 days, has a total of 72 lunar eclipse events including 57 umbral lunar eclipses (42 partial lunar eclipses and 15 total lunar eclipses). Solar Saros 138 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series.

This is the first of the series that passes through the center of the Earth's shadow. The last occurrence was the May 2004 lunar eclipse. The next occurrence is the May 2040 lunar eclipse.

Metonic series

edit

This 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

edit

A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[14] This lunar eclipse is related to two annular solar eclipses of Solar Saros 138.
