07/25/2016 – Ephemeris – Hermes’ Harp

July 25, 2016

Ephemeris for Monday, July 25th.  The Sun rises at 6:21.  It’ll be up for 14 hours and 54 minutes, setting at 9:16.  The Moon, 1 day before last quarter, will rise at 12:34 tomorrow morning.

High up in the eastern sky at 11 p.m. can be found a bright star just north of a small, narrow, but very distinctive parallelogram of stars.  They are the stars of the constellation Lyra the harp.  The bright star is Vega, one of the twenty-one brightest stars, first magnitude stars.  Vega is actually the 5th brightest night-time star. The harp, according to Greek mythology, was invented by the Greek god Hermes.  The form of the harp in the sky, is as he had invented it: by stretching strings across a tortoise shell.  Hermes gave it to his half-brother Apollo, who in turn gave it to the great musician Orpheus.  In binoculars, near Vega, two stars appear together.  They barely appear to the unaided eye as one star, called Epsilon Lyrae.

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