Partial Lunar Eclipse: April 25, 2013

Geographic Region: Europe, Africa, Asia, Australia

The first lunar eclipse of 2013 occurs at the Moon's ascending node in southern Virgo about 12° east of Spica (mv = +1.05).  It is visible primarily from the Eastern Hemisphere. The Moon's contact times with Earth's shadows are listed below.

 

Penumbral Eclipse Begins:   18:03:38 UT
Partial Eclipse Begins:   19:54:08 UT
Greatest Eclipse:   20:07:30 UT
Partial Eclipse Ends:   20:21:02 UT
Penumbral Eclipse Ends:   22:11:26 UT

 

At the instant of greatest eclipse the umbral eclipse magnitude will reach 0.0147.  This event is barely partial with just 0.5 arc-minutes of the Moon's northern limb dipping into umbral shadow.  Consequently, the partial phase lasts less than 27 minutes.

To catch the entire event, one must be located in eastern Europe or Africa, central Asia or western Australia.  At the instant of greatest eclipse the Moon will be at the zenith for an observer just east of Madagascar.  Eastern parts of South America will experience moonrise with the eclipse already in progress, but none of the eclipse is visible from North America.

The April 25 eclipse belongs to Saros 112, a series of 72 eclipses in the following sequence: 7 penumbral, 21 partial, 15 total, 22 partial, and 7 penumbral lunar eclipses (Espenak and Meeus, 2009).  In particular, the April 25 event is the last partial eclipse in Saros 112.
