October 2005 lunar eclipse
Partial lunar eclipse 17 October 2005
A partial lunar eclipse took place on Monday 17 October 2005, the second of two lunar eclipses in 2005. A tiny bite out of the Moon may have been visible at maximum, though just 6.25% of the Moon was shadowed in a partial eclipse which lasted for nearly 56 minutes and was visible over east Asia, Australasia, and most of the North America. A shading across the Moon from the Earth's penumbral shadow should have been visible at maximum eclipse.

Metonic series
This eclipse is the last of four Metonic cycle lunar eclipses on the same date, 17–18 October, 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.

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 partial solar eclipses of Solar Saros 153.
