A total lunar eclipse occurred at the Moon’s ascending node of orbit on Sunday, November 9, 2003,[1] with an umbral magnitude of 1.0197. 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 1.2 days before apogee (on November 10, 2003, at 7:00 UTC), the Moon's apparent diameter was smaller.[2]
This lunar eclipse is the second of a tetrad, with four total lunar eclipses in series, the others being on May 16, 2003; May 4, 2004; and October 28, 2004.
This was the last of 14 total lunar eclipses of Lunar Saros 126, which started on June 19, 1769 and ended on November 9, 2003.
The eclipse was completely visible over eastern North and South America, much of Africa, and Europe, seen rising over western North and South America and the Pacific Ocean and setting over east Africa and west, central, and south Asia.[3]

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.
This eclipse is the second of five Metonic cycle lunar eclipses on the same date, 8–9 November, each separated by 19 years:
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 133.
