I was sitting on my sofa watching t.v. on July 16, 2016 at 10:14 P.M. I glanced out my window toward the North East and noticed what I first thought was an airplane. Then I noticed several red and blue lights which appeared to be rotating and pulsating at time same time from lift to right. Then I realized it couldn’t be an airplane. I really couldn’t be sure if the object was actually moving. After about 4 seconds the object disappeared as I was looking at it. I know it didn’t disappear into the clouds, because their were no clouds in the sky at the time. It was there then it was gone in a flash. Very exciting to witness.
