11/23/2015 – Ephemeris – An occultation of Aldebaran by the Moon will be visible to much of the northern US Thursday morning

November 23, 2015

Ephemeris for Monday, November 23rd.  The Sun will rise at 7:49.  It’ll be up for 9 hours and 18 minutes, setting at 5:08.   The Moon, 2 days before full, will set at 5:58 tomorrow morning.

Thursday morning, Thanksgiving Day here in the US, the Moon will occult or pass in front of the bright star Aldebaran for the northern half of the United States, and Canada.  I have a special post on my blog dated yesterday, November 22nd.  It’s titled Aldebaran Occultation November 26, 2015 from Northern Michigan (click here) with all the details.  My blog is bobmoler.wordpress.com, or do an Internet search for Bob Moler, That’s Moler spelled M-O-L-E-R, no extra letters.  Aldebaran is the bright orange star in the face of the constellation Taurus the bull.  You will need at least a pair of binoculars to pick out Aldebaran next to the Moon.  Aldebaran will disappear at about 5:38 a.m. and reappear about 6:29 a.m. for Interlochen and Traverse City.

Times are for the Traverse City/Interlochen area of Michigan. They may be different for your location.  The November 22 post has instructions on how to calculate the occultation  times for your location, and has a map to see if you can view the occultation at all.

Addendum
