A total lunar eclipse took place at the Moon's descending node of the orbit on Tuesday, May 24, 1910 with an umbral eclipse magnitude of 1.09503. A total lunar eclipse takes place when the Earth comes between the Sun and the Moon and its shadow covers the Moon. Eclipse watchers can see the Moon turn red when the eclipse reaches totality. Total eclipses of the Moon happen at Full Moon when the Sun, Earth, and Moon are aligned to form a line. The astronomical term for this type of alignment is syzygy, which comes from the Greek word for being paired together. The Moon does not have its own light but shines because its surface reflects the Sun's rays. During a total lunar eclipse, the Earth comes between the Sun and the Moon and blocks any direct sunlight from reaching the Moon. The Sun casts the Earth's shadow on the Moon's surface. A shallow total eclipse saw the Moon in relative darkness for 49 minutes and 29.5 seconds. The Moon was 9.503% of its diameter into the Earth's umbral shadow, and should have been significantly darkened. The partial eclipse lasted for 3 hours, 35 minutes and 22.9 seconds in total.

Eclipse season

This event followed the total solar eclipse of May 9, 1910.

Visibility

It was completely visible over Australia, the Americas, Europe and Africa, seen rising over Australia and setting over Europe and Africa.

Saros series

Lunar saros series 129, repeating every 18 years and 11 days, containing 71 events, has 11 total lunar eclipses. The first total lunar eclipse of this series was on May 24, 1910, and last will be on September 8, 2090. The longest occurrence of this series was on July 16, 2000 when totality lasted 106 minutes and 24.6 seconds.

It last occurred on May 11, 1892 and will next occur on June 3, 1928.

This is the 32nd member of Lunar Saros 129, and the first total eclipse. The next event is the June 1928 lunar eclipse. Lunar Saros 129 contains 11 total lunar eclipses between 1910 and 2090. Solar Saros 136 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series.

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).^[1] This lunar eclipse is related to two total solar eclipses of Solar Saros 136.

May 18, 1901	May 29, 1919
