April 2005 lunar eclipse
Penumbral lunar eclipse 24 April 2005
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
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.
