A penumbral lunar eclipse

Lunar eclipse

A lunar eclipse occurs when the Moon passes behind the Earth so that the Earth blocks the Sun's rays from striking the Moon.

will take place on May 25, 2013, the second of three lunar eclipses in 2013. It will be visually imperceptible due to the small entry into the penumbral shadow.

This event marks the beginning of Saros series 150.

Visibility

Lunar year (354 days)

This eclipse is the one of five lunar eclipses in a short-lived series. The lunar year series repeats after 12 lunations or 354 days (Shifting back about 10 days in sequential years). Because of the date shift, the Earth's shadow will be about 11 degrees west in sequential events.
