Bob Moler's Ephemeris Blog

This is Ephemeris for Friday, July 10th. Today the Sun will be up for 15 hours and 21 minutes, setting at 9:28, and it will rise tomorrow at 6:08. The Moon, 3 days past last quarter, will rise at 2:38 tomorrow morning.

The Grand Traverse Astronomical Society will host its July meeting tonight at 9 PM at Northwestern Michigan College’s Joseph H Rogers Observatory. The later meeting time allows us to have viewing after the meeting starts in darker skies. The program is informal. The Artemis 2 mission brought back a treasure trove of photographs of the earth and the moon. We will be showing some of them and having everyone have a chance to comment on them, ask questions, explore them further, or explain them. This is the same topic that was proposed for the June meeting, which was canceled due to unforeseen circumstances. Afterward, about 10 PM, if it’s clear, there will be viewing of the heavens through the observatory’s telescopes. The observatory is located south of Traverse City, on Birmley Rd. The meeting is also on Zoom; see gtastro.org.

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; EDT, UT – 4 hours) unless stated otherwise. Times will be different for other locations.
