07/21/2022 – Ephemeris – Observing the heavens from the shore of Sleeping Bear Bay
This is Ephemeris for Thursday, July 21st. Today the Sun will be up for 15 hours and 3 minutes, setting at 9:20, and it will rise tomorrow at 6:18. The Moon, 1 day past last quarter, will rise at 1:35 tomorrow morning.
There’s an observatory on the shores of Sleeping Bear Bay near Glen Arbor that is open to the public twice a week on clear nights. It’s the Leelanau School’s Lanphier Observatory, which is open Wednesday and Thursday evenings weather permitting from 10 p.m. to midnight through August 25th. The Leelanau School is located at 1 Old Homestead Road, off M22, just north of Glen Arbor. The Observatory is behind the Student Center and across the Crystal River. It’s a bit of a hike. It will help to take a flashlight for heading back in the dark. The observatory dome contains a 14-inch telescope on a computerized mount, and smaller telescopes may be available on the observatory deck. The observatory is run by Norm Wheeler, retired instructor of the school. Get there early to enjoy the sunset on Lake Michigan.
The astronomical event times given are for the Traverse City/Interlochen area of Michigan (EDT, UT – 4 hours). They may be different for your location.
Addendum

07/28/11 – Ephemeris – GTAS Night at the Lanphier Observatory
Thursday, July 28th. The sun rises at 6:24. It’ll be up for 14 hours and 48 minutes, setting at 9:12. The moon, 2 days before new, will rise at 5:08 tomorrow morning.
The Lanphier Observatory in Glen Arbor is open Wednesday and Thursday nights through August but only on clear evenings from 10 to midnight. The observatory is located close to the beach at the Leelanau School, just east of Glen Arbor on M22. I was asked by Norm Wheeler, who is the director of the observatory to help him out tonight, so I’m also inviting the crew over from the Grand Traverse Astronomical Society to help out with me. The Delta Aquarid meteor shower is reaching peak around now. These will seem to come from the southeast in the morning. Also beginning to show themselves in the Perseid meteor shower. The full moon will dim their maximum on August 12th, but early meteors can be seen from now until then when the moon isn’t up.
