Ephemeris: 08/15/2025 – The Milky Way on August evenings

August 15, 2025

This is Ephemeris for Friday, August 15th. Today the Sun will be up for 14 hours and 2 minutes, setting at 8:48, and it will rise tomorrow at 6:46. The Moon, 1 day before last quarter, will rise at 11:41 this evening.

August is the best time to see the most southern part of the Milky Way. The constellation of Sagittarius the Archer or for us moderns a Teapot is due South at 10:30 this evening . The Milky Way runs up from the South moving high in the east and ends up in the northeast and the constellation of Cassiopeia the queen which looks like the letter W. We will have to wait several months or stay up for several hours tonight to see the Milky Way cross overhead, but by then the southern part of the Milky Way will have begun to set in the southwest. So this is the time to enjoy looking towards the center our Galaxy which is located right above the tip of the spout of Sagittarius, but behind a cloud of dust.

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.
