A penumbral lunar eclipse occurred at the Moon’s descending node of orbit on Tuesday, March 14, 2006,[1] with an umbral magnitude of −0.0584. It was a relatively rare total penumbral lunar eclipse, with the Moon passing entirely within the penumbral shadow without entering the darker umbral shadow. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A penumbral lunar eclipse occurs when part or all of the Moon's near side passes into the Earth's penumbra. 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. Occurring about 2.2 days after apogee (on March 12, 2006, at 20:45 UTC), the Moon's apparent diameter was smaller.[2]

Visibility

[edit]

The eclipse was completely visible much of Africa, eastern South America, Europe, and west Asia, seen rising over North and South America and setting over much of Asia and western Australia.[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.

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 in nearly the same location relative to the background stars.

  2. 2025 Mar 14.29 - total (123)
  3. 2044 Mar 13.82 - total (133)

Saros 113

[edit]

The eclipse belongs to Saros series 113, and is the 63rd of 71 lunar eclipses in the series. The first penumbral eclipse of saros cycle 113 began on 29 April 888 AD, first partial eclipse on 14 July 1014, and total first was on 20 March 1429. The last total eclipse occurred on 7 August 1645, last partial on 21 February 1970, and last penumbral eclipse on 10 June 2150.[5]

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).[6] This lunar eclipse is related to two total solar eclipses of Solar Saros 120.
