Description: I live in Pennsylvania and around 9:30 PM this evening 12/12/2013 I observed a very large “V” shaped grey silent steady moving object in sky. It was moving south. I did not see any lights on object. The size of object appeared to be very large. It was moving at a steady speed and then just disappeared into the night sky. If you have any questions or if you have any information on what I observed you may reply to my email.
