Ephemeris for Friday, July 17th.  Today the Sun will be up for 15 hours and 11 minutes, setting at 9:24.   The Moon, 2 days past new, will set at 10:07 this evening, and tomorrow the Sun will rise at 6:14.

High in the east at 11 p.m. can be found a bright star just above 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, called first magnitude stars.  Vega is actually the 5th brightest night time star. The harp, according to Greek mythology, was invented by the 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.

Looking westward tomorrow night the planet Venus will appear about 2 moon widths above the crescent Moon.

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