Bob Moler's Ephemeris Blog

Ephemeris for Tuesday, May 15th.  Today the sun will be up for 14 hours and 50 minutes, setting at 9:04.   The moon, 3 days past last quarter, will rise at 3:51 tomorrow morning.  Tomorrow the sun will rise at 6:13.

Sunday evening’s partial eclipse will begin within a minute of 8:19 p.m. for most locations in the IPR listening area.  The sun will be only about a 7 degree angle above the horizon at that time.  That’s slightly less than the width of your fist held at arm’s length.  At sunset, at about 9:10 p.m., with the flat horizon of Lake Michigan about 50% of the sun will be covered.  The farther inland you are, or east from the shore, the start of the eclipse will be about the same time, but sunset will be earlier one minute every 12 miles east you are.  An obstructed horizon will make sunset earlier.  Thursday and Friday I’ll have safe eclipse observing tips.  Or go to my May 8th entry at bobmoler.wordpress.com for an illustrated entry.

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