# May 2069 lunar eclipse

A total lunar eclipse will occur at the Moon’s ascending node of orbit on Monday, May 6, 2069, with an umbral magnitude of 1.3242. It will be a central lunar eclipse, in which part of the Moon will pass through the center of the Earth's shadow. 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 2.3 days after apogee (on May 4, 2069, at 1:40 UTC), the Moon's apparent diameter will be smaller.
This lunar eclipse will be the third of an almost tetrad, with the others being on May 17, 2068 (partial); November 9, 2068 (total); and October 30, 2069 (total).
This will be the first central eclipse of Lunar Saros 132.
The Moon will also occult the bright star Alpha Librae as seen from the southern hemisphere a few hours before greatest eclipse.

## Visibility

The eclipse will be completely visible over western North America, Antarctica, and the eastern Pacific Ocean, seen rising over east Asia and Australia and setting over central and eastern North America and South America.
* The moon's hourly motion across the Earth's shadow in the constellation of Libra.

## 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.
Eclipse season of April–May 2069 :
| April 21 Descending node (new moon) | May 6 Ascending node (full moon) | May 20 Descending node (new moon) |
| Partial solar eclipse Solar Saros 120 | Total lunar eclipse Lunar Saros 132 | Partial solar eclipse Solar Saros 158 |

### Lunar eclipses of 2067–2070

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 27, 2067 occurs in the previous 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)

### 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.

### 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 :
| 1807 May 21 (Saros 108) | 1807 May 21 (Saros 108) | 1818 Apr 21 (Saros 109) | 1818 Apr 21 (Saros 109) | 1829 Mar 20 (Saros 110) | 1829 Mar 20 (Saros 110) | 1840 Feb 17 (Saros 111) | 1840 Feb 17 (Saros 111) | 1851 Jan 17 (Saros 112) | 1851 Jan 17 (Saros 112) |

### 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.

### Half-Saros cycle

A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros). This lunar eclipse is related to two total solar eclipses of Solar Saros 139.
