10/06/2015 – Ephemeris – Deneb our home-town star

October 6, 2015

Ephemeris for Tuesday, October 6th.  The Sun will rise at 7:46.  It’ll be up for 11 hours and 27 minutes, setting at 7:14.   The Moon, 2 days past last quarter, will rise at 2:36 tomorrow morning.

We, here in Traverse City, Michigan have a pretty unique relation to the bright star Deneb, as is any location near 45 degrees north latitude.  Tonight at 9:23  Deneb will be three-quarters of a degree due north of the zenith.  Due north means that it’s on our meridian, a line you may remember from your school days.  For astronomers it passes from the north point on the horizon, through the overhead point or zenith to the south point on the horizon.  Also due to our latitude Deneb is circumpolar, meaning that it doesn’t quite set on a clean northern horizon.  Deneb and 56 other stars are used for celestial navigation, which is still taught in case the GPS system goes down due to solar or enemy action.

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