On 25 April 2013, a partial lunar eclipse will be visible in Africa, Australia, Europe and most of Asia. In Egypt, the eclipse will start at 20:03:38, when the Moon enters the pale outer component of Earth’s shadow, the penumbra. The partial phase, during which only a tiny portion of the Moon will be darkened, will start at 21:54:08, when the Moon skims the inner dark component of Earth’s shadow, the umbra.
 
The brief partial phase will last about 27 minutes. The eclipse will end shortly after the beginning of the 26 April, when the Moon exits Earth’s shadow completely, at 00:11:26.
