# January 1934 lunar eclipse

A partial lunar eclipse occurred at the Moon’s descending node of orbit on Tuesday, January 30, 1934, with an umbral magnitude of 0.1120. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A partial lunar eclipse occurs when one part of the Moon is in the Earth's umbra, while the other part is in 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 2.9 days after apogee (on January 27, 1934, at 18:55 UTC), the Moon's apparent diameter was smaller.

## Visibility

The eclipse was completely visible over Asia and Australia, seen rising over Africa and Europe and setting over western North America and the central Pacific Ocean.

## 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 January–February 1934 :
| January 30 Descending node (full moon) | February 14 Ascending node (new moon) |
| Partial lunar eclipse Lunar Saros 113 | Total solar eclipse Solar Saros 139 |

### Lunar eclipses of 1933–1936

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 March 12, 1933 and September 4, 1933 occur in the previous lunar year eclipse set.

### 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.
