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 Ptolemy: The Good, Bad and the Ugly. His second century view of the universe held sway in the western world fourteen hundred years into the Christian era. He was a geographer, astronomer, and an astrologer. His greatest work, which I will explore, is known as the Almagest, meaning The Greatest in Arabic (Not his title). 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.
