Suddenly at 12:16 AM, our security lights came on. When I looked out the window an object cruised slowly in front of our home flashing multiple lights that were Red, Green, Orange, and White. The object appeared to be circular and had not visible means of propulsion and was completely silent. The security lights were enabled in sequence as the object cruised across our property with no other visible means triggering them on the ground. My wife also witnessed this seem event as well. The event took approx 5 minutes overall
