A total lunar eclipse occurred at the Moon’s descending node of orbit on Monday, November 29, 1993,[1] with an umbral magnitude of 1.0876. 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 4.75 days after apogee (on November 24, 1993, at 12:35 UTC), the Moon's apparent diameter was smaller.[2]

Visibility

The eclipse was completely visible over North America and western South America, seen rising over northeast Asia, eastern Australia, and the western and central Pacific Ocean and setting over eastern South America, much of Africa, and Europe.[3]

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.

Lunar eclipses of 1991–1994

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.[5]

The penumbral lunar eclipses on January 30, 1991 and July 26, 1991 occur in the previous lunar year eclipse set.

Saros 135

This eclipse is a part of Saros series 135, repeating every 18 years, 11 days, and containing 71 events. The series started with a penumbral lunar eclipse on April 13, 1615. It contains partial eclipses from July 20, 1777 through October 28, 1939; total eclipses from November 7, 1957 through July 6, 2354; and a second set of partial eclipses from July 16, 2372 through September 19, 2480. The series ends at member 71 as a penumbral eclipse on May 18, 2877.

The longest duration of totality will be produced by member 37 at 106 minutes, 13 seconds on May 12, 2264. All eclipses in this series occur at the Moon’s descending node of orbit.[6]

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.

Half-Saros cycle

A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[8] This lunar eclipse is related to two total solar eclipses of Solar Saros 142.
