03/04/2022 – Ephemeris – Tonight, an illustrated Zoom talk: “Light Pollution: Cause and Effect”

March 4, 2022

This is Ephemeris for Friday, March 4th. Today the Sun will be up for 11 hours and 19 minutes, setting at 6:34, and it will rise tomorrow at 7:13. The Moon, 2 days past new, will set at 8:56 this evening.

The Grand Traverse Astronomical Society (GTAS) will hold a virtual meeting and program at 8 pm tonight via Zoom. For the program, Dr. Jerry Dobek, astronomy professor at Northwestern Michigan College, will present an illustrated talk – Light Pollution: Cause and Effect. The focus of the talk will be on the general causes and effects of light pollution, as well as examples of proper lighting. Dr. Dobek has helped write lighting ordinances for governments here and around the nation. A virtual star party will start around 9 pm, also hosted by Dr. Dobek, but only if it’s clear in Traverse City. It will feature the wonders of the winter and early spring sky. Instructions to join the meeting and a link can be found on the society’s website, gtastro.org. All are welcome.

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.

If COVID-19 stays tamped down this spring and summer, the GTAS will be working with the rangers of the Sleeping Bear Dunes National Lakeshore to schedule monthly sun and star parties. The areas of the park we observe from are generally northwest (above, left in the image above) of Traverse City, near the shore of Lake Michigan.
