Penumbral Lunar Eclipse of 25-26 April 2013

21/04/2013 01:58

      This is a deep penumbral eclipse with a penumbral magnitude of 0.9866 ( For comparison full moon has magnitude of -13 which can be seen at the end of this eclipse). It should be easily visible to the naked eye as a dusky shading in the northern half of the Moon. The times of the major phases are listed below (Indian timings in bracket).

                                                                 Penumbral Eclipse Begins:    18:03:41 UT        (25 Apr, 11:35 pm)

                                                                 Greatest Eclipse:                        20:08:37 UT        (26 Apr, 01:38 am)

                                                                 Penumbral Eclipse Ends:        22:11:23 UT        (26 Apr, 03:40 am)

        Note that the beginning and end of a penumbral eclipse are not visible to the eye. In fact, no shading can be detected until about 2/3 of the Moon's disk is immersed in the penumbra. An interesting exercise is to note when penumbral shading is first and last seen.

 

            Figure shows the path of the Moon through the penumbra as well as a map of Earth showing the regions of eclipse visibility. Observers in Asia (including INDIA), China, Africa will have the best views.

   

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. Complete details for the series can be found at:
