# October 2050 lunar eclipse

A total lunar eclipse will occur at the Moon’s descending node of orbit on Sunday, October 30, 2050, with an umbral magnitude of 1.0549. 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 1.9 days after perigee (on October 28, 2050, at 5:10 UTC), the Moon's apparent diameter will be larger.
This lunar eclipse is the second of a tetrad, with four total lunar eclipses in series, the others being on May 6, 2050; April 26, 2051; and October 19, 2051.
During the eclipse, NGC 877 will be occulted by the Moon over the southeast Pacific Ocean, South America and the Atlantic Ocean. Deep-sky objects are rarely occulted during a total eclipse from any given spot on Earth.$^{:161}$

## Visibility

The eclipse will be completely visible over North and South America, west Africa, and western Europe, seen rising over the central and eastern Pacific Ocean and setting over central and east Africa, eastern Europe, and west, central, and south Asia.

## 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 October–November 2050 :
| October 30 Descending node (full moon) | November 14 Ascending node (new moon) |
| Total lunar eclipse Lunar Saros 127 | Partial solar eclipse Solar Saros 153 |

### Lunar eclipses of 2049–2052

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 15, 2049 occurs in the previous lunar year eclipse set.

### Saros 127

This eclipse is a part of Saros series 127, repeating every 18 years, 11 days, and containing 72 events. The series started with a penumbral lunar eclipse on July 9, 1275. It contains partial eclipses from November 4, 1473 through May 18, 1780; total eclipses from May 29, 1798 through November 9, 2068; and a second set of partial eclipses from November 20, 2086 through June 17, 2429. The series ends at member 72 as a penumbral eclipse on September 2, 2555.
The longest duration of totality was produced by member 35 at 101 minutes, 46 seconds on July 23, 1888. 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.
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.
