May 13, 2016 Comments off

Ephemeris for Friday, May 13th.  Today the Sun will be up for 14 hours and 46 minutes, setting at 9:02.   The Moon, at first quarter today, will set at 2:59 tomorrow morning.  Tomorrow the Sun will rise at 6:15.

The Grand Traverse Astronomical Society will host a public viewing night for Astronomy Day tomorrow night, that’s Saturday the 14th, starting at 9 p.m.  It will be at Northwestern Michigan College’s Joseph Rogers Observatory.  If its clear the slightly gibbous moon will be featured along with Jupiter, Mars and the ringed planet Saturn and other wonders of the spring sky.  The observatory is located south of Traverse City, on Birmley Road between Garfield and Keystone roads.  For the society these, twice monthly star parties at the observatory and sidewalk astronomy outings by members, to the Sleeping Bear Dunes National Lakeshore and other locations are what they do.

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

Other thoughts

I was checking out the Solar and Heliospheric Observatory (SOHO) LASCO C3 animation and Venus is making an entrance from the right as it heads for superior conjunction on June 6.  June 6?  Hmm. Wasn’t that last transit or Venus on June 5th 2012.  We and Venus should be near the line of nodes again, where the planes of our respective orbits cross.  I cranked up Stellarium, and sure enough the Sun will occult Venus that day… Not that we could see it.
