Friday, September 30th.  The sun will rise at 7:38.  It’ll be up for 11 hours and 46 minutes, setting at 7:25.   The moon, half way from new to first quarter, will set at 9:14 this evening.

Let’s look at the skies for the month of October which starts tomorrow.  The sun will still be moving south rapidly.  Daylight hours in the Interlochen/Traverse City area will drop from 11 hours and 43 minutes tomorrow to 10 hours 14 minutes on the 31st.  The altitude of the sun above the southern horizon at local noon will be 42 degrees tomorrow, and will descend to 31degrees on Halloween, also in the Interlochen area.  The Straits area will have the sun a degree lower.  Local noon, when the sun is due south will be about 1:30 p.m. in Interlochen.  The planet Jupiter will move higher in the southeast in the evening next month.  I’m hoping with the sun’s activity increasing we’ll get a shot at seeing some northern lights next month.
