03/21/2017 – Ephemeris – Let’s find Cancer the crab

March 21, 2017

Ephemeris for Tuesday, March 21st.  The Sun will rise at 7:43.  It’ll be up for 12 hours and 13 minutes, setting at 7:56.  The Moon, 1 day past last quarter, will rise at 4:26 tomorrow morning.

At 10 this evening, the faint constellation, and member of the Zodiac, Cancer the crab is located in the south half way between the bright stars Castor and Pollux of the constellation Gemini, high in the south and the bright star Regulus in Leo the lion in the southeast.  Cancer is very dim, looking like an upside-down Y if it’s stars can be made out.  In the center of Cancer is a fuzzy spot to the unaided eye.  In binoculars or a low power telescope this fuzzy spot becomes a cluster of stars.  It is the Beehive cluster.  At 577 light years away, according to the latest measurements, it is one of the closest star clusters, but more distant than the Pleiades and Hyades the face of Taurus the bull off in the west.

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