May 2087 lunar eclipse
A total lunar eclipse will occur at the Moon’s ascending node of orbit on Saturday, May 17, 2087,[1] with an umbral magnitude of 1.4568. 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 about 2 days after apogee (on May 15, 2087, at 15:25 UTC), the Moon's apparent diameter will be smaller.[2] VisibilityThe eclipse will be completely visible over east and southeast Asia, Australia, and Antarctica, seen rising over much of Africa, central and eastern Europe, and west, central, and south Asia and setting over the central and eastern Pacific Ocean.[3] Eclipse detailsShown below is a table displaying details about this particular solar eclipse. It describes various parameters pertaining to this eclipse.[4]
Eclipse seasonThis 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.

Saros 132Lunar saros series 132, repeating every 18 years and 11 days, has a total of 71 lunar eclipse events including 44 umbral lunar eclipses (32 partial lunar eclipses and 12 total lunar eclipses).
There are 11 series events between 1901 and 2100, grouped into threes (called an exeligmos), each column with approximately the same viewing longitude on earth.
Inex seriesThe 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 40. All events in this series shown (from 1000 to 2500) are central total lunar eclipses.
Half-Saros cycleA lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[6] This lunar eclipse is related to two total solar eclipses of Solar Saros 139.
