March 2007 lunar eclipse

(Redirected from 3 March 2007 lunar eclipse)

A total lunar eclipse occurred at the Moon’s descending node of orbit on Saturday, March 3, 2007,[1] with an umbral magnitude of 1.2347. 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 2.9 days before apogee (on March 6, 2007, at 22:40 UTC), the Moon's apparent diameter was smaller.[2]

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.

Metonic series

edit

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.

  1. 1988 Mar 03.675 – Partial (113)
  2. 2007 Mar 03.972 – Total (123)
  3. 2026 Mar 03.481 – Total (133)
  4. 2045 Mar 03.320 – Penumbral (143)
  1. 1988 Aug 27.461 – partial (118)
  2. 2007 Aug 28.442 – total (128)
  3. 2026 Aug 28.175 – partial (138)
  4. 2045 Aug 27.578 – penumbral (148)
   

Saros 123

edit

Lunar saros series 123, repeating every 18 years and 11 days, has 25 total lunar eclipses. The first total lunar eclipse of this series was on July 16, 1628, and last will be on April 4, 2061. The two longest occurrence of this series were on September 20, 1736 and October 1, 1754 when totality lasted 106 minutes.


It last occurred on 20 February 1989 and will next occur on 14 March 2025.

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 130.
