09/10/2012 – Ephemeris – The constellation Cepheus the king

September 10, 2012

Ephemeris for Monday, September 10th.  The sun will rise at 7:16.  It’ll be up for 12 hours and 45 minutes, setting at 8:01.   The moon, 2 days past last quarter, will rise at 2:25 tomorrow morning.

The stars of autumn are taking over the eastern evening sky as the equinox approaches.  Looking to the northeastern sky at 10 p.m. we find the W shaped constellation of Cassiopeia the queen.  It is opposite the pole star Polaris from the Big Dipper.  Above Cassiopeia is a dim church steeple shaped constellation of Cepheus the king.  The steeple is toppled to the left.  It also lies on the line between the bright star Deneb, the northeastern most star of the Summer Triangle and Polaris.  Cepheus is a king and the husband of the more notorious Cassiopeia.  The Milky Way flows through a corner of Cepheus.  One of its stars is Delta Cephei is the first of a type of variable star that have allowed us to measure distances to the galaxies.

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