I was at home and went out onto the balcony of my apartment to look at the stars as I always do. When I looked up I saw the lights rotating and coming back to a center point, then spreading out and rotating again. At first I wondered if, because of the sparse cloud cover, if it might be spot lights from airport. It was a center light, a soft white light, edges mutted by a little cloud cover, then separated and broke off into 4 lights, expanding out into a large circle, rotating and then coming back again only to keep repeating. This went on for over 2 hours.I was a little spooked, but excited as I had not seen a ufo in many years.I lost signt of the object when I finally came indoors.
