At twenty five past 11pm I was sitting on my front veranda having a smoke when something in the north caught my attention. A very large object was crossing the sky from east to west. It was what I considered round due to all the lights that were flashing on and off around the object. Being on the flight path, I know what the airplanes look like and this object was much bigger and round, like a huge wheel. I heard no sound as I would with aircraft. When all the lights flashed, they flashed in unison around the whole object.
