Ephemeris for Thursday, August 30th.  The sun will rise at 7:03.  It’ll be up for 13 hours and 18 minutes, setting at 8:21.   The moon, 1 day before full, will set at 7:12 tomorrow morning.

Let’s look ahead at the skies for September a couple of days early. The sun is moving at its greatest speed in its retreat to the south. Daylight hours in the Interlochen/Traverse City area and will drop from 13 hours and 12 minutes Saturday to 11 hours 44 minutes on the 30th. The altitude of the sun above the southern horizon at local noon will be 54 degrees Saturday, and will descend to 42 degrees on the 30th. Folks in the straits area will see the sun a degree lower than that.  The official season of summer is getting short too, so enjoy it while you can.  Summer ends and autumn begins at 10:49 a.m. on September 22nd.  That Harvest Moon will be on the 29th.  Tomorrows full moon will be the rare Blue Moon – More on that tomorrow.

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