November 2003 lunar eclipse

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.

Visibility

edit

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]

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.

Lunar eclipses of 2002–2005

edit

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 eclipse on June 24, 2002 occurs in the previous lunar year eclipse set.

Saros 126

edit

This eclipse is a part of Saros series 126, repeating every 18 years, 11 days, and containing 70 events. The series started with a penumbral lunar eclipse on July 18, 1228. It contains partial eclipses from March 24, 1625 through June 9, 1751; total eclipses from June 19, 1769 through November 9, 2003; and a second set of partial eclipses from November 19, 2021 through June 5, 2346. The series ends at member 70 as a penumbral eclipse on August 19, 2472.

The longest duration of totality was produced by member 36 at 106 minutes, 27 seconds on August 13, 1859. All eclipses in this series occur at the Moon’s ascending 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.

Metonic series

edit

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

The Metonic cycle repeats nearly exactly every 19 years and represents a Saros cycle plus one lunar year. Because it occurs on the same calendar date, the Earth's shadow will be in nearly the same location relative to the background stars.

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).[8] This lunar eclipse is related to two total solar eclipses of Solar Saros 133.
