Bob Moler's Ephemeris Blog

Ephemeris for Friday, December 6th.  The sun will rise at 8:04.  It’ll be up for 8 hours and 57 minutes, setting at 5:02.   The moon, 3 days before first quarter, will set at 9:40 this evening.

This evening’s meeting of the Grand Traverse Astronomical Society starting at 8 p.m. at Northwestern Michigan College’s Rogers Observatory will be a new December program.  In the past yours truly alternated between a program on the Star of Bethlehem and the cosmology of the Bible.  This year I’m presenting Ancient Cosmologies, a look at the cosmologies of many mostly pre-scientific cultures,  including how the Biblical world view was influenced by one of them.  Then we’ll see the beginnings of Greek scientific thought that codified by Ptolemy in the second century AD, held sway for 1,500 years.   At 9 p.m. there will be a star party at the observatory, and another program if it’s cloudy.  All are welcome.

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