A totallunar eclipse will occur at the Moon’sascending node of orbit on Thursday, April 14, 2033,[1] with an umbralmagnitude of 1.0955. 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 2.9 days beforeapogee (on April 11, 2033, at 22:30 UTC), the Moon's apparent diameter will be smaller.[2]
This lunar eclipse is the third of atetrad, with four total lunar eclipses in series, the others being onApril 25, 2032;October 18, 2032; andOctober 8, 2033.
The eclipse will be completely visible overeast Africa, most ofAsia, and westernAustralia, seen rising overwest andcentral Africa,Europe, and easternSouth America and setting overnortheast Asia and Australia.[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 onJune 5, 2031 occurs in the previous lunar year eclipse set.

This eclipse is a part ofSaros series 132, repeating every 18 years, 11 days, and containing 71 events. The series started with a penumbral lunar eclipse on May 12, 1492. It contains partial eclipses from August 16, 1636 throughMarch 24, 1997; total eclipses fromApril 4, 2015 through August 2, 2213; and a second set of partial eclipses from August 13, 2231 through November 30, 2411. The series ends at member 71 as a penumbral eclipse on June 26, 2754.
The longest duration of totality will be produced by member 36 at 106 minutes, 6 seconds onJune 9, 2123. All eclipses in this series occur at the Moon’sascending node of orbit.[6]

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.
