Penumbral Lunar Eclipse of 18-19 October 2013

17/10/2013 19:08

The last lunar eclipse of the year is a relatively deep penumbral eclipse with a magnitude of 0.7649. It should be easily visible to the naked eye as a dusky shading in the southern half of the Moon. The times of the major phases are listed below (Indian timings in bracket).

 

                                                                      Penumbral Eclipse Begins: 21:50:38 UT (19 Oct, 03:23 am)

                                                                      Greatest Eclipse: 23:50:17 UT (19 Oct, 05:20 am)

                                                                      Penumbral Eclipse Ends: 01:49:49 UT (19 Oct, 07:18 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. This would put the period of nominal eclipse visibility from about 23:30 to 00:10 UT. Keep in mind that this is only an estimate. Atmospheric conditions and the observer's visual acuity are important factors to consider. 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 Europe and Africa will also see the entire event, while eastern Asia misses the end because of moonset.

 

The October 18-19 penumbral lunar eclipse is the 52nd member of Saros 117, a series of 71 eclipses in the following sequence: 8 penumbral, 9 partial, 24 total, 7 partial, and 23 penumbral lunar eclipses (Espenak and Meeus, 2009).
