# April 2033 lunar eclipse

A total lunar eclipse will occur at the Moon’s ascending node of orbit on Thursday, April 14, 2033, with an umbral magnitude of 1.0955. 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 2.9 days before apogee (on April 11, 2033, at 22:30 UTC), the Moon's apparent diameter will be smaller.
This lunar eclipse is the third of a tetrad, with four total lunar eclipses in series, the others being on April 25, 2032; October 18, 2032; and October 8, 2033.

## Visibility

The eclipse will be completely visible over east Africa, most of Asia, and western Australia, seen rising over west and central Africa, Europe, and eastern South America and setting over northeast Asia and Australia.

## Eclipse season

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.
Eclipse season of March–April 2033 :
| March 30 Descending node (new moon) | April 14 Ascending node (full moon) |
| Partial solar eclipse Solar Saros 120 | Total lunar eclipse Lunar Saros 132 |

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

### Saros 132

This eclipse is a part of Saros 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 through March 24, 1997; total eclipses from April 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 on June 9, 2123. All eclipses in this series occur at the Moon’s ascending node of orbit.

### 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.
Series members between 1801 and 2200 :

### 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.
