Bob Moler's Ephemeris Blog

This is Ephemeris for Friday, June 27th. Today the Sun will be up for 15 hours and 33 minutes, setting at 9:32, and it will rise tomorrow at 5:59. The Moon, 2 days past new, will set at 11:44 this evening.

Weather permitting, the Grand Traverse Astronomical Society and the Park Rangers will host a star party at Sleeping Bear Dunes National Lakeshore, at the Dune Climb starting around 9:00 PM. The parking lane closest to the dune will be blocked off for telescopes. Note… the start time is before actual sunset, however the Moon should be visible from near sunset and after until nearly 11 PM Also on tap will be binary stars, an interesting treat through the telescope. The Rangers leave around 11:00 PM however if it stays clear and there’s enough interest, society members with their telescopes will stay longer. Two other star parties are planned this summer: on July 26th and August 23rd.

The astronomical event times given in this blog are for the Traverse City/Interlochen area of Michigan (Lat 44.7° N, Long 85.7° W; EDT, UT – 4 hours) unless stated otherwise. Times will be different for other locations.
