one large light moved slowly across the sky at a very high altitude. four smaller lights seemed to come from within the large light as it came to a stop. these four smaller lights made looping motions around the larger light. each made simaler movements in differant directions to cover a wide area around the larger light. after a couple of hours it was taking about 15 minutes for the smaller lights to make there loop it had gotten so large. we were all turning and watching differant ones as they traveled outward.I would guess they were traveling 10 to 15 miles out from the center. finally the four small lights came back in position around the large light in the center and one at a time they went back to the larger light. after a few minutes the larger light went straight up into the sky until it was out of sight.
