I took this photo at the corner of Riverside Dr. and Eastland Ave. in Nashville, TN at 2144 CST on 5 June 2011. There was a large triangular form with lights at each point. It appear to be massive, over a football field in size. It also appeared to be over the river or close to it. It gained altitude while rotating clockwise and the "faded out" while heading NW. The rear lights faded before the front one.
