October 2032 lunar eclipse

A total lunar eclipse will occur at the Moon’s descending node of orbit on Monday, October 18, 2032,^[1] with an umbral magnitude of 1.1039. 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 2.1 days after perigee (on October 16, 2032, at 17:25 UTC), the Moon's apparent diameter will be larger.^[2]

Eclipse season

See also: Eclipse cycle

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.

Lunar eclipses of 2031–2034

This 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.^[5]

The penumbral lunar eclipse on June 5, 2031 occurs in the previous lunar year eclipse set.

Saros 127

This eclipse is a part of Saros series 127, repeating every 18 years, 11 days, and containing 72 events. The series started with a penumbral lunar eclipse on July 9, 1275. It contains partial eclipses from November 4, 1473 through May 18, 1780; total eclipses from May 29, 1798 through November 9, 2068; and a second set of partial eclipses from November 20, 2086 through June 17, 2429. The series ends at member 72 as a penumbral eclipse on September 2, 2555.

The longest duration of totality was produced by member 35 at 101 minutes, 46 seconds on July 23, 1888. All eclipses in this series occur at the Moon’s descending node of orbit.^[6]

Tritos series

This eclipse is a part of a tritos cycle, repeating at alternating nodes every 135 synodic months (≈ 3986.63 days, or 11 years minus 1 month). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic 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.

Inex series

This eclipse is a part of the long period inex cycle, repeating at alternating nodes, every 358 synodic months (≈ 10,571.95 days, or 29 years minus 20 days). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee). However, groupings of 3 inex cycles (≈ 87 years minus 2 months) comes close (≈ 1,151.02 anomalistic months), so eclipses are similar in these groupings.

Half-Saros cycle

A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).^[8] This lunar eclipse is related to two partial solar eclipses of Solar Saros 134.
