This was about 10:00 PM.I was standing on the southwest side of the house looking up at it and realized it was silent and was only about at the level of the treetops, say 20 feet up in the air.  
The next thing I was aware of was that I was back in my bedroom and the sun was coming up and I sensed it leave because the trees started whipping around and then stopped abruptly and I heard the sound of helicopters coming from the East.  They flew right over my house and had search lights combing the woods. They kept flying loudly to the West.
The next day I called my friend and before I could tell her anything she said that she was woken up by her dog barking at sunrise and looked out her back door and saw a brightly lit object above the trees to the north and heard helicopters coming from the East and then the object took off sudenly to the West and three helicopters followed it but were much too slow to keep up.

Witness indicates that date of incident is approximate.  PD
