Bob Moler's Ephemeris Blog

This Ephemeris for Thursday, September 26th. Today the Sun will be up for 11 hours and 56 minutes, setting at 7:31, and it will rise tomorrow at 7:36. The Moon, 2 days past last quarter, will rise at 2:02 tomorrow morning.

High in the northeast sky at 9:00 PM can be found the constellation of Cassiopeia the queen. Its stars make a letter W in the sky. It is circumpolar, meaning that it never sets, as it appears to move around the North Pole of the sky. In the summer it is a W low in the north. It becomes kind of an open and angular number 3 in the autumn. In the winter it is overhead and looks like an M. In springtime it looks like the Greek capital letter Sigma in the northwest. I will visit Cassiopeia later this autumn and relate her story and other autumn constellations including her daughter Andromeda, husband King Cepheus, future son-in-law Perseus and his horse Pegasus, and the sea monster, Cetus.

The astronomical event times given are for the Traverse City/Interlochen area of Michigan (EDT, UT – 4 hours). Times will be different for other locations.
