01/20/2017 – Ephemeris – Orion’s greater hunting dog

January 20, 2017

Ephemeris for Friday, January 20th.  The Sun will rise at 8:12.  It’ll be up for 9 hours and 22 minutes, setting at 5:35.  The Moon, 1 day past last quarter, will rise at 2:29 tomorrow morning.

The great winter constellation or star group Orion the Hunter, is located in the south-southeastern sky at 9 p.m.  His elongated rectangle of a torso is almost vertical.  In the center of the rectangle are three stars in a line that make his belt.  As a hunter, especially one of old, he has two hunting dogs.  The larger, Canis Major can be found by following the three belt stars of Orion down and to the left.  There lies the  brilliant star called Sirius, also known as the Dog Star.  It’s in the heart of a stick figure dog low in the southeast facing Orion that appears to be begging.  I’ll have more to say about Sirius in the future, but there’s a fine star cluster, called M41, at the 5 o’clock position from Sirius easily visible in binoculars or a small telescope.

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