Friday, September 16th.  The sun will rise at 7:22.  It’ll be up for 12 hours and 29 minutes, setting at 7:51.   The moon, half way from full to last quarter, will rise at 9:27 this evening.

This evening the Grand Traverse Astronomical Society will host a viewing night at Northwestern Michigan College’s Rogers Observatory starting at 9 p.m.  The featured objects of the evening will be the planet Jupiter and the moon.  Jupiter is the largest planet and has 65 satellites, of which the four discovered by Galileo are large enough to be easily seen.  Three of these are larger than our moon.  The observatory is located south of Traverse City, on Birmley Road between Garfield and Keystone roads.  Also this weekend, tomorrow members of the society will bring their telescopes to the Leland Heritage Celebration to safely view the sun, which has recently become vary active.  Times for this event are 10 a.m to 3 p.m.

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