Lunar Eclipse November 28 2012

Penumbral Lunar Eclipse of November

The last lunar eclipse of 2012 is a deep penumbral eclipse with a magnitude of 0.9155. 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.

Penumbral Eclipse Begins: 12:14:58 UT
Greatest Eclipse: 14:33:00 UT
Penumbral Eclipse Ends: 16:51:02 UT

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 eclipse visibility from approximately 14:00 to 15:00 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 6 shows the path of the Moon through the penumbra as well as a map of Earth showing the regions of eclipse visibility. Eastern Canada and the USA will miss the eclipse entirely since it begins after moonset. Observers in western Canada and the USA will have the best views with moonset occurring sometime after mid-eclipse. To catch the entire event, one must be in Alaska, Hawaii, Australia, or East Asia.

The November 28 penumbral lunar eclipse is the 11th member of Saros 145, a series of 71 eclipses in the following sequence: 18 penumbral, 10 partial, 15 total, 20 partial, and 8 penumbral lunar eclipses (Espenak and Meeus, 2009). Complete details for the series can be found at:

Good morning Susie77:
I'll be watching for the partial eclipse but our forecast is: rain, Rain....Oops: 28th you say?
I looked for the moon earlier this morning and it may well have been ecplipsed but there is mist and trees. I went out just now and "the moon is down" here.
