Bright red light seen in the skies of San Bruno, CA maneuvering slowly towards the west.

There was a red light which seemed to be moving slowly west, away from our location.  It stopped momentarily, changed directions as if it was going to turn and make a circle, stopped again, and then move a little more west.  It did this two or three times then came to stop for approximately 5 minutes.  Then began to move west again very slowly and steadily towards the coast until it disappeared out of sight over the San Bruno Hills.  The distance of the object was unknown.  We were located on El Camino Real at the Tanforan shopping center it was a little before 2300 when we noticed it.
