01/31/2013 – Ephemeris – Preview of February Skies

January 31, 2013 Comments off

Ephemeris for Thursday, January 31st.  The sun will rise at 8:02.  It’ll be up for 9 hours and 48 minutes, setting at 5:50.   The moon, 3 days before last quarter, will rise at 11:06 this evening.

February is the shortest month, even so the daylight hours through out the month will be getting longer.  Daylight hours will increase from 9 hours and 50 minutes tomorrow to 11 hours and 7 minutes on the 28th.  The sunrise time will decrease from 8:00 tomorrow to 7:21 at months end.  The sunset times will increase from 5:51 tomorrow to 6:28 on the 28th.  Along with that the altitude of the sun at noon will increase from 28 degrees today to nearly 38 degrees at month’s end.  It will be a degree lower for folks in the Straits area because they are a degree of latitude farther north.  Local noon, by the way for Interlochen and Traverse City is about 12:55 p.m. We are expecting clearer skies later this month as the lakes cool.

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