June 2020 ->

A penumbral lunar eclipse occurred at the Moon’s ascending node of orbit on Friday, January 10, 2020,[1] with an umbral magnitude of −0.1146. 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 2.8 days before perigee (on January 13, 2020, at 15:20 UTC), the Moon's apparent diameter was larger.[2]

This eclipse was the first of four penumbral lunar eclipses in 2020, with the others occurring on June 5, July 5, and November 30.

## Visibility

[edit]

The eclipse was completely visible over east Africa, Europe, and Asia, seen rising over the west Africa and northern North America and setting over Australia and the central Pacific Ocean.[3]

## Eclipse season

[edit]

See also: Eclipse cycle

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.

### Lunar eclipses of 2016–2020

[edit]

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.[5]

The penumbral lunar eclipses on March 23, 2016 and September 16, 2016 occur in the previous lunar year eclipse set, and the penumbral lunar eclipses on June 5, 2020 and November 30, 2020 occur in the next lunar year eclipse set.

### Saros 144

[edit]

This eclipse is a part of Saros series 144, repeating every 18 years, 11 days, and containing 71 events. The series started with a penumbral lunar eclipse on July 29, 1749. It contains partial eclipses from March 28, 2146 through June 23, 2290; total eclipses from July 4, 2308 through January 28, 2651; and a second set of partial eclipses from February 8, 2669 through June 8, 2867. The series ends at member 71 as a penumbral eclipse on September 4, 3011.

The longest duration of totality will be produced by member 38 at 104 minutes, 53 seconds on September 7, 2416. All eclipses in this series occur at the Moon’s ascending node of orbit.[6]

Eclipses are tabulated in three columns; every third eclipse in the same column is one exeligmos apart, so they all cast shadows over approximately the same parts of the Earth.

### Tritos series

[edit]

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

[edit]

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

[edit]

A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[8] This lunar eclipse is related to two partial solar eclipses of Solar Saros 151.
