A totallunar eclipse occurred at the Moon’sascending node of orbit on Tuesday, November 8, 2022,[1] with an umbralmagnitude of 1.3607. It was acentral lunar eclipse, in which part of theMoon passed through thecenter of theEarth'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 asolar eclipse, which can only be viewed from a relatively small area of the world, a lunar eclipse may be viewed from anywhere on thenight 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'sshadow is smaller. Occurring about 5.6 days beforeapogee (on November 14, 2022, at 1:40 UTC), the Moon's apparent diameter was smaller.[2]
This eclipse surpassed theprevious eclipse as the longest total lunar eclipse visible from nearly all ofNorth America sinceAugust 17, 1989, and untilJune 26, 2029.[3][4][5][6] A lunaroccultation ofUranus happened during the eclipse.[7] It was the first total lunar eclipse onElection Day in US history.[8][9] The next Election Day total lunar eclipse won't occur until November 8, 2394.[9] This event was referred in media coverage as a "beaver blood moon".[10][11]
This lunar eclipse was the last of what was almosta tetrad, with the others being onMay 26, 2021 (total);November 19, 2021 (partial); andMay 16, 2022 (total).
The eclipse was completely visible overnortheast Asia andNorth America, seen rising overAsia andAustralia and setting over eastern North America andSouth America.[12]

This eclipse is part of aneclipse 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 afortnight.

This eclipse is a member of asemester series. An eclipse in a semester series of lunar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternatingnodes of the Moon's orbit.[14]
The penumbral lunar eclipses onJanuary 10, 2020 andJuly 5, 2020 occur in the previous lunar year eclipse set.

TheMetonic cycle repeats nearly exactly every 19 years and represents aSaros 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.

This eclipse is a part ofSaros series 136, repeating every 18 years, 11 days, and containing 72 events. The series started with a penumbral lunar eclipse on April 13, 1680. It contains partial eclipses from July 11, 1824 throughSeptember 14, 1932; total eclipses fromSeptember 26, 1950 through July 7, 2419; and a second set of partial eclipses from July 18, 2437 through October 3, 2563. The series ends at member 72 as a penumbral eclipse on June 1, 2960.
The longest duration of totality will be produced by member 35 at 101 minutes, 23 seconds on April 21, 2293. All eclipses in this series occur at the Moon’sascending node of orbit.[15]

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

This eclipse is a part of atritos cycle, repeating at alternating nodes every 135synodic months (≈ 3986.63 days, or 11 years minus 1 month). Their appearance and longitude are irregular due to a lack of synchronization with theanomalistic month (period of perigee), but groupings of 3 tritos cycles (≈ 33 years minus 3 months) come close (≈ 434.044 anomalistic months), so eclipses are similar in these groupings.
