10/04/2016 – Ephemeris – Celestial dolphin and Cupid’s arrow

October 4, 2016

Ephemeris for Tuesday, October 4th.  The Sun will rise at 7:45.  It’ll be up for 11 hours and 31 minutes, setting at 7:16.  The Moon, 4 days past new, will set at 9:28 this evening.

There’s two small constellations I’ve overlooked in the heat of Summer.  Located above the southernmost star of the Summer Triangle of three of the brightest stars in the sky, which is nearly overhead at 9 p.m., is the tiny constellation of Delphinus the dolphin, which is seen high in the south.  Delphinus’ 6 stars in a small parallelogram with a tail, really does look like a dolphin leaping out of the water.  The parallelogram itself has the name Job’s Coffin.  The origin of this asterism or informal constellation is unknown.  Of the dolphin itself: the ancient Greeks appreciated this aquatic mammal as we do.  There’s another tiny constellation to the right of Delphinus, Sagitta the arrow, which represents Cupid’s dart.

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