A total lunar eclipse took place on Wednesday, May 3, 1939. A shallow total eclipse saw the Moon in relative darkness for 1 hour and 2 minutes. The Moon was 18% of its diameter into the Earth's umbral shadow, and should have been significantly darkened. The partial eclipse lasted for 3 hours and 27 minutes in total.

Saros series

Lunar saros series 130, repeating every 18 years and 11 days, has a total of 71 lunar eclipse events including 56 umbral lunar eclipses (42 partial lunar eclipses and 14 total lunar eclipses). Solar Saros 137 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series.

Greatest First

The greatest eclipse of the series will occur on 2029 Jun 26, lasting 102 minutes.[1]

Inex series

The inex series repeats eclipses 20 days short of 29 years, repeating on average every 10571.95 days. This period is equal to 358 lunations (synodic months) and 388.5 draconic months. Saros series increment by one on successive Inex events and repeat at alternate ascending and descending lunar nodes.

This period is 383.6734 anomalistic months (the period of the Moon's elliptical orbital precession). Despite the average 0.05 time-of-day shift between subsequent events, the variation of the Moon in its elliptical orbit at each event causes the actual eclipse time to vary significantly. It is a part of Lunar Inex series 35.

Half-Saros cycle

A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[2] This lunar eclipse is related to two solar eclipses of Solar Saros 137.

April 28, 1930 May 9, 1948
