Tomorrow we’ll start the month when the promise of spring is finally fulfilled.  Daylight hours in the Interlochen/Traverse City area will increase from 14 hours and 15 minutes tomorrow to 15 hours 19 minutes on the 31st.  The altitude, or angle, of the sun above the southern horizon at local noon will ascend from 60 degrees today to 67 degrees at month’s end.  The altitude of the sun in the Straits area will be a degree lower than that but your daylight will be a few minutes longer.  Local apparent noon this month, when the sun passes due south, will be about 1:38 p.m.  The big event of this month will be a partial eclipse of the sun on Sunday May 20th, where we’ll see about 45 minutes of the eclipse as the sun sets.

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