Three lights travelling in a clockwise pattern behind my home.On the 23 of January, 2009 at approximately 2330 hours while in the rear of my home in Kenner, Louisiana I looked out almost exactly due west of my home and saw what appeared to be two or three lights in the sky circling in a clockwise pattern over what I know to be swamp, and open water. It appeared that all the lights though holding a steady pattern were travelling at different speeds since one seemed to be overtaking the others. Occasionally one light would come slightly into the forefront before disappearing behind clouds towards what would be the west from my vantage point. One light appeared to almost change shapes as it travelled at times looking almost like a bird and at others looking only like a round or oval piece of light. I do not know what it was; however, as a 5-year veteran of law enforcement in this area I know I have never seen anything like it.
