Friday, September 9th.  The sun will rise at 7:14.  It’ll be up for 12 hours and 50 minutes, setting at 8:04.   The moon, 3 days before full, will set at 5:32 tomorrow morning.

Tomorrow is the Grand Traverse Astronomical Society’s 4th star party of 2011 at the Sleeping Bear Dunes National Lakeshore. This time we’ll be at the Dune Climb.  The bottom, not the top, in or near the parking lot.  We’ll have the bright moon early.  We’ll be also looking at binary stars, star clusters and the Ring Nebula.  Toward the end of the evening Jupiter will be high enough to view.  The event will be canceled if it’s too cloudy.  There will be another star party, this one to celebrate the Lakeshore’s 41st anniversary in October, so stay tuned for that one.  So far we’ve had no outright cancellations, but two of the nights were hampered by clouds.  Our one absolutely clear night cleared just after sunset, and after an earlier rain shower.

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