02/16/2015 – Ephemeris – The Winter Circle

February 16, 2015

Feb 16.  This is Bob Moler with Ephemeris for President’s Day, Monday, February 16th.  The sun will rise at 7:42.  It’ll be up for 10 hours and 30 minutes, setting at 6:12.   The moon, 2 days before new, will rise at 6:25 tomorrow morning.

The winter skies are blessed with more first magnitude stars than any other season.  That’s a full one-third of the total are seen is a relatively small area.  Six of these stars lie in a large circle centered on the seventh.  This circle is up at 9 p.m.  Starting high overhead is Capella in Auriga the charioteer.  Moving down clockwise is Aldebaran in the face of Taurus the Bull.  Then down to Orion’s knee we find Rigel.  Down and left is the brightest star of all Sirius the Dog Star in Canis Major, lowest of these stars in the south-southeast.  Moving up and left is Procyon in Canis Minor, Above Procyon is Pollux in Gemini the twins.  All these are centered on Betelgeuse the bright red star in Orion’s shoulder.

Times are for the Traverse City/Interlochen area of Michigan.  They may be different for your location.
