A totallunar eclipse will occur at the Moon’sdescending node of orbit on Sunday, March 13, 2044,[1] with an umbralmagnitude of 1.2050. A lunar eclipse occurs when theMoon moves into theEarth'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 6.2 days afterperigee (on March 7, 2044, at 15:30 UTC), the Moon's apparent diameter will be larger.[2]
This lunar eclipse is the third of atetrad, with four total lunar eclipses in series, the others being onMarch 25, 2043;September 19, 2043; andSeptember 7, 2044.
The eclipse will be completely visible overeast Africa,eastern Europe, and much ofAsia, seen rising overwest Africa,western Europe, and easternSouth America and setting overnortheast Asia andAustralia.[3]

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.[5]
The penumbral lunar eclipse onOctober 28, 2042 occurs 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 in nearly the same location relative to the background stars.

This eclipse is a part ofSaros series 133, repeating every 18 years, 11 days, and containing 71 events. The series started with a penumbral lunar eclipse on May 13, 1557. It contains partial eclipses from August 7, 1683 through December 17, 1899; total eclipses fromDecember 28, 1917 through August 3, 2278; and a second set of partial eclipses from August 14, 2296 through March 11, 2639. The series ends at member 71 as a penumbral eclipse on June 29, 2819.
The longest duration of totality will be produced by member 35 at 101 minutes, 41 seconds onMay 30, 2170. All eclipses in this series occur at the Moon’sdescending node of orbit.[6]

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.
