Thursday, September 15th.  The sun will rise at 7:21.  It’ll be up for 12 hours and 32 minutes, setting at 7:53.   The moon, 3 days past full, will rise at 8:56 this evening.

I don’t usually talk about the moon after it becomes full, but because of the harvest moon effect its still rises early.  The moon’s phase is now a waning gibbous, with the sunset line now crossing the moon from right to left.  Visible are the dark seas including to the upper right the scallop shell shaped Sea of Serenity.  In telescopes at its right edge will be the crater Posidonus a flat crater, 58 miles in diameter, with low walls with an inner partial crater ring within.  Larger telescopes may be able to see cracks or rilles in its floor.  The sea south of Serenity is Tranquility where Apollo 11 landed and by tomorrow night the sun will nearly have set there as well as having encroached on Serenity

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