Ephemeris for Tuesday, July 15th.  Today the sun will be up for 15 hours and 13 minutes, setting at 9:24.   The moon, half way from full to last quarter, will rise at 11:19 this evening.  Tomorrow the sun will rise at 6:12.

Very 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 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.  The sun has a motion with respect to most stars around it. Its direction is towards the vicinity of Lyra.

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