The Moon's hourly motion across the Earth's shadow in the constellation of Virgo.

A penumbral lunar eclipse took place on Sunday 24 April 2005, the first of two lunar eclipses in 2005. At maximum eclipse, 86.5% of the Moon's disc was partially shaded by the Earth, which caused a slight shadow gradient across its disc; this subtle effect may have been visible to careful observers. No part of the Moon was in complete shadow. The eclipse lasted 4 hours and 6 minutes overall, and was visible from east Asia, Australia, and the Americas.

Metonic series

[edit]

This eclipse is the last of four Metonic cycle lunar eclipses on the same date, 23–24 April, 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 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).[1] This lunar eclipse is related to two solar eclipses of Solar Saros 148.
