Bob Moler's Ephemeris Blog

This is Ephemeris for Friday, December 1st. Today the Sun will be up for 9 hours and 4 minutes, setting at 5:03, and it will rise tomorrow at 8:00. The Moon, halfway from full to last quarter, will rise at 8:51 this evening.

Tonight at this month’s meeting of the Grand Traverse Astronomical Society which will be at 8 pm at Northwestern Michigan College’s Rogers Observatory. I will be giving an illustrated talk about The Astronomy of the Ancient Greeks. The Greek astronomical view of the universe held sway in the western world sixteen hundred years into the Christian era. I’ll look at the early Greek astronomers from Thales, the first astronomer and philosopher in the 6th century BCE to Ptolemy in the 2nd century CE. Afterward if it’s clear we’ll have a star party starting about 9 pm. The meeting will also be available via Zoom, which I’ll be using to give the talk. Go to gtastro.org for instructions and a link.

The astronomical event times given are for the Traverse City/Interlochen area of Michigan (EST, UT –5 hours). They may be different for your location.
