Ephemeris: 01/02/2026 – I’ll try to talk about Ptolemy again tonight
The meeting has been changed to Zoom only due to the weather!
This is Ephemeris for Friday, January 2nd. The Sun will rise at 8:20. It’ll be up for 8 hours and 53 minutes, setting at 5:14. The Moon, 1 day before full, will set at 8:57 tomorrow morning.
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, the Bad and the Ugly. This was originally scheduled for the December meeting, which was canceled due to no heat in the building. So I’ll try again tonight. Ptolemy’s second century view of the universe held sway in the western world fourteen hundred years into the Christian era. 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 viewing of Saturn and Jupiter. 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 in this blog are for the Traverse City/Interlochen area of Michigan (Lat 44.7° N, Long 85.7° W; EST, UT – 5 hours) unless stated otherwise. Times will be different for other locations.
