Light formation with large disk at center

I was on the north shore of Lake Superior later in the evening and over the lake came a formation of lights that at first appeared to be a very long/wide aircraft with two bright yellow lights and smaller green and orange lights on either side. It came in close very fast and had no sound at all. It appeared to stop and hover and a few smaller individual lights came shooting off and quickly faded and disappeared into the distance. All of this with absolutely no sound. The larger object then seemed to just get farther away as the lights eventually faded completely. It was hard to tell if the object was going up or away or turned away in a certain direction. The entire event lasted only a couple of minutes. What I remember most was the fact it was absolutely silent and seemed to hover very gracefully while the small lights shot out very quick and graceful as well.
