Neighbor having a party, I looked out of his door from his garage that leads to his back yard. 3 orange/white lights in a triangle formation rotating counter clockwise were noted. I had 2 other neighbors witness as well. No sound noted, the object or objects were just above the tree line. Suddenly the lights began to move to the west and then all 3 lights went out. After the lights were not visible, there was 1 light that came into view, almost as it were to trail the previous object or objects.
