A total lunar eclipse will occur at the Moon’s ascending node of orbit on Saturday, September 19, 2043,[1] with an umbral magnitude of 1.2575. 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 2.8 days before perigee (on September 21, 2043, at 20:20 UTC), the Moon's apparent diameter will be larger.[2]
This lunar eclipse is the second of a tetrad, with four total lunar eclipses in series, the others being on March 25, 2043; March 13, 2044; and September 7, 2044.
Visibility
[edit | edit source]The eclipse will be completely visible over South America, western Europe, and west Africa, seen rising over North America and setting over east Africa, eastern Europe, and west, central, and south Asia.[3]

Eclipse season
[edit | edit source]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 2042–2045
[edit | edit source]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 October 28, 2042 occurs in the previous lunar year eclipse set.
Saros 128
[edit | edit source]This eclipse is a part of Saros series 128, repeating every 18 years, 11 days, and containing 71 events. The series started with a penumbral lunar eclipse on June 18, 1304. It contains partial eclipses from September 2, 1430 through May 11, 1827; total eclipses from May 21, 1845 through October 21, 2097; and a second set of partial eclipses from November 2, 2115 through May 17, 2440. The series ends at member 71 as a penumbral eclipse on August 2, 2566.
The longest duration of totality was produced by member 37 at 100 minutes, 43 seconds on July 26, 1953. 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
[edit | edit source]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
[edit | edit source]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.
