woke for some reason at 03:30, my bed is right by my window which was open and faces NNW. I looked out the window and just above treetop level I saw a black triangular object that was silent and moving slowly to the NNW.It was quite large probably about the size of a 737. It had no wings it was just a triangle shape. There was two very bright lights at the rear of the triangle, that seemed to me to be as big as the craft was deep. I did not note any flashing marker lights, it slowly just moved off in the direction I noted with no sounds of any kind. Where I stay It is very quiet at that time of the morning so if it had made any type of noise I would have heard it.
