Dr. Dobek has helped write lighting ordinances for governments here and around the nation. A star party will start around 8 pm, but only if it’s clear. The observatory is located south of Traverse City, on Birmley Road. The meeting is also available via Zoom. A link can be found on the society’s website, gtastro.org.
