A total lunar eclipse will occur at the Moon’s descending node of orbit on Thursday, August 7, 2036,[1] with an umbral magnitude of 1.4556. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A total lunar eclipse occurs when the Moon's near side entirely passes into the Earth's umbral shadow. 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. A total lunar eclipse can last up to nearly two hours, while a total solar eclipse lasts only a few minutes at any given place, because the Moon's shadow is smaller. Occurring only about 11 hours after apogee (on August 6, 2036, at 16:00 UTC), the Moon's apparent diameter will be smaller.[2]

This lunar eclipse will be the second of an almost tetrad, with the others being on February 11, 2036 (total); January 31, 2037 (total); and July 27, 2037 (partial).

The southern tip of the Moon will pass through the center of the Earth's shadow. This is also the last central lunar eclipse of Saros cycle 129.

Visibility

[edit]

The eclipse will be completely visible over South America and west Africa, seen rising over much of North America and the eastern Pacific Ocean and setting over Africa, Europe, and west, central, and south Asia.[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. The first and last eclipse in this sequence is separated by one synodic month.

This is the 39th member of Lunar Saros 129. The previous event was the July 2018 lunar eclipse. The next event is the August 2054 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.

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