# May 2107 lunar eclipse

A penumbral lunar eclipse will occur at the Moon’s ascending node of orbit on Saturday, May 7, 2107, with an umbral magnitude of −0.9356. 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. The Moon's apparent diameter will be near the average diameter because it will occur 6.8 days after perigee (on April 30, 2107, at 10:00 UTC) and 6.9 days before apogee (on May 14, 2107, at 1:50 UTC).
This eclipse will be too small to be visually perceptible.

## Visibility

The eclipse will be completely visible over much of North and South America, western Europe, west and southern Africa, and Antarctica.

## 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. The first and last eclipse in this sequence is separated by one synodic month.

### Lunar eclipses of 2103–2107

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 eclipses on January 23, 2103 and July 19, 2103 occur in the previous lunar year eclipse set, and the penumbral lunar eclipses on April 7, 2107 and October 2, 2107 occur in the next lunar year eclipse set.

### Metonic series

The Metonic cycle repeats nearly exactly every 19 years and represents a Saros 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 series has 9 events centered on May 6th and October 30th: (saros number)
| Ascending node | Descending node |
| 2031 May 07.160 - penumbral (112) 2050 May 06.937 - total (122) 2069 May 06.380 - total (132) 2088 May 05.677 - partial (142) 2107 May 07.186 - penumbral (152) | 2031 Oct 30.323 - penumbral (117) 2050 Oct 30.139 - total (127) 2069 Oct 30.148 - total (137) 2088 Oct 30.125 - partial (147) |

### 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.
