Bob Moler's Ephemeris Blog

Ephemeris for Tuesday, July 23rd.  The sun rises at 6:19.  It’ll be up for 14 hours and 58 minutes, setting at 9:17.   The moon, 1 day past full, will rise at 9:38 this evening.

The Lanphier Observatory of the Leelanau School is open this summer from 10 p.m. to midnight on Wednesday and Thursday evenings until Labor Day but only if it’s clear.  The Leelanau School is located off M22 east of Glen Arbor.  The observatory is located at the edge of the beach.  Tomorrow night the Grand Traverse Astronomical Society will be hosting the viewing night at the Lanphier Observatory.  Celestial wonders to be viewed will be Venus and Saturn, plus some of the brighter wonders of the night sky beyond the solar system.  My informal connection with the Lanphier Observatory goes back to 1975 shortly after the Ephemeris program began.  It was a gift to the school by then summer resident Charles Lanphier.

Times are for the Traverse City/Interlochen area of Michigan.  They may be different for your location.
