# June 1947 lunar eclipse

A partial lunar eclipse occurred at the Moon’s descending node of orbit on Tuesday, June 3, 1947, with an umbral magnitude of 0.0202. 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 3.2 days before apogee (on June 6, 1947, at 23:00 UTC), the Moon's apparent diameter was smaller.

## Visibility

The eclipse was completely visible over east and southern Africa, west, central, and south Asia, western Australia, and Antarctica, seen rising over Europe, west Africa, and eastern South America and setting over east Asia and eastern Australia.

## 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 May–June 1947 :
| May 20 Ascending node (new moon) | June 3 Descending node (full moon) |
| Total solar eclipse Solar Saros 127 | Partial lunar eclipse Lunar Saros 139 |

### Lunar eclipses of 1944–1947

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 February 9, 1944 and August 4, 1944 occur in the previous lunar year eclipse set.
Lunar eclipse series sets from 1944 to 1947 :

### Saros 139

This eclipse is a part of Saros series 139, repeating every 18 years, 11 days, and containing 79 events. The series started with a penumbral lunar eclipse on December 9, 1658. It contains partial eclipses from June 3, 1947 through August 7, 2055; total eclipses from August 17, 2073 through May 30, 2542; and a second set of partial eclipses from June 9, 2560 through August 25, 2686. The series ends at member 75 as a penumbral eclipse on April 13, 3065.
The longest duration of totality will be produced by member 31 at 102 minutes, 39 seconds on November 2, 2199. All eclipses in this series occur at the Moon’s descending node of orbit.

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

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.

### 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 146.
