Ephemeris: 09/01/2023 – GTAS meeting tonight – Dr. Jerry Dobek goes over to the dark side

September 1, 2023

This is Ephemeris for Friday, September 1st. Today the Sun will be up for 13 hours and 14 minutes, setting at 8:19, and it will rise tomorrow at 7:06. The Moon, 2 days past full, will rise at 9:24 this evening.

Tonight at 8 p.m. at the meeting of the Grand Traverse Astronomical Society at Northwestern Michigan College’s Rogers Observatory, and on Zoom. Observatory Director Dr. Jerry Dobek will be giving a talk on what he calls dark material. This is from a new book he collaborated on: The Barnard Objects – Then and Now, a look at dark nebulae, comparing E. E. Barnard’s Black and White photographic plates to modern color digital photography. Dark nebulae are clouds of gas and dust seen in the summer Milky Way. After the meeting, at 9 p.m. the society will host a star party to view a rather bright night sky including Saturn. The observatory is located south of Traverse City on Birmley Road between Garfield and Keystone roads. Zoom instructions will be at gtastro (dot) org.

The astronomical event times given are for the Traverse City/Interlochen area of Michigan (EDT, UT –4 hours). They may be different for your location.
