A total lunar eclipse will occur at the Moon’s ascending node of orbit on Sunday, April 25, 2032,[1] with an umbral magnitude of 1.1925. 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. The Moon's apparent diameter will be near the average diameter because it will occur 6.7 days after apogee (on April 18, 2032, at 23:00 UTC) and 8.1 days before perigee (on May 3, 2032, at 16:45 UTC).[2]

This lunar eclipse is the first of a tetrad, with four total lunar eclipses in series, the others being on October 18, 2032; April 14, 2033; and October 8, 2033.

Visibility

The eclipse will be completely visible over east Asia, Australia, and Antarctica, seen rising over east and central Africa, eastern Europe, and west and central Asia and setting over the eastern Pacific Ocean and western North America.[3]

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 122

This eclipse is a part of Saros series 122, repeating every 18 years, 11 days, and containing 74 events. The series started with a penumbral lunar eclipse on August 14, 1022. It contains partial eclipses from April 10, 1419 through June 24, 1545; total eclipses from July 5, 1563 through May 6, 2050; and a second set of partial eclipses from May 17, 2068 through July 21, 2176. The series ends at member 74 as a penumbral eclipse on October 29, 2338.

The longest duration of totality was produced by member 39 at 100 minutes, 5 seconds on October 11, 1707. All eclipses in this series occur at the Moon’s ascending node of orbit.[6]

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.

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.
