Bob Moler's Ephemeris Blog

Ephemeris for Tuesday, October 1st.  The sun will rise at 7:40.  It’ll be up for 11 hours and 41 minutes, setting at 7:22.   The moon, 3 days before new, will rise at 5:10 tomorrow morning.

Let’s look at the skies for the month of October.  The sun will still be moving south rapidly.  Daylight hours in the Interlochen/Traverse City area will drop from 11 hours and 41 minutes today to 10 hours 13 minutes on the 31st.  The altitude of the sun above the southern horizon at local noon will be 42 degrees today, and will descend to 31 degrees on Halloween, also in the Interlochen/Traverse City 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/Traverse City.  Comet ISON is currently about a sixth as bright as original estimates would predict.  However comets can unpredictable in their brightness.  So we will know for sure in two months.

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