# March 2024 lunar eclipse

A penumbral lunar eclipse occurred at the Moon’s descending node of orbit on Monday, March 25, 2024, with an umbral magnitude of −0.1304. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A penumbral lunar eclipse occurs when part or all of the Moon's near side passes into the Earth's penumbra. 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. Occurring about 2.2 days after apogee (on March 23, 2024, at 11:45 UTC), the Moon's apparent diameter was smaller.
This was the deepest penumbral eclipse overall since May 5, 2023, and the deepest for North and South America since February 11, 2017.

## Visibility

The eclipse was completely visible over North and South America, seen rising over eastern Australia and northeast Asia and setting over west Africa and western Europe.

## 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 2024 :
| March 25 Descending node (full moon) | April 8 Ascending node (new moon) |
| Penumbral lunar eclipse Lunar Saros 113 | Total solar eclipse Solar Saros 139 |

### Lunar eclipses of 2024–2027

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 July 18, 2027 occurs in the next lunar year eclipse set.
Lunar eclipse series sets from 2024 to 2027 :

### Saros 113

This eclipse is a part of Saros series 113, repeating every 18 years, 11 days, and containing 71 events. The series started with a penumbral lunar eclipse on April 29, 888 AD. It contains partial eclipses from July 14, 1014 through March 10, 1411; total eclipses from March 20, 1429 through August 7, 1645; and a second set of partial eclipses from August 18, 1663 through February 21, 1970. The series ends at member 71 as a penumbral eclipse on June 10, 2150.
The longest duration of totality was produced by member 38 at 103 minutes, 6 seconds on June 5, 1555. All eclipses in this series occur at the Moon’s descending 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.

### 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.
