Partial Eclipse of the Moon

October 17, 2013; 4:05 PM ET

A eclipse of the Moon, officially called a penumbral eclipse, will occur the night of the 18th into the 19th.

It will be visible from the Americas (for the end), Europe, Africa and most of Asia (the beginning of the eclipse will be visible in east Asia). The western part of the Philippines (including western Luzon and Palawan) can see the penumbral eclipse at moonset.

The eclipse will last for about four hours. Being a penumbral eclipse, will be hard to see to the untrained eye.

A penumbral eclipse occurs when the Moon passes through the Earth's penumbra. The Earth's penumbra is the region in which only a portion of the light source is obscured by the occluding body. The penumbra causes a subtle darkening of the Moon's surface.
