Approximately 15 lights appeared in the sky and the craft began doing maneuvers in which I could see that it was disk shaped.

I was on my porch at 9 pm looking at the Moon when the 15 lights appeared in the sky and the craft began doing maneuvers in which I could see it was disk shaped with lights around the edges of the craft. It then slowly moved across the sky to the Northwest until I could no longer see the lights. There was no color to the lights and I heard no sounds. I am a graduate student in psychology at Fort Hays State University. I enjoy watching the stars at night and this was the first object I've seen that I have no idea what it was.
