October 2005 lunar eclipse

A partial lunar eclipse took place on Monday, October 17, 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, October 17–18, 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.
