Very large, very bright light moving incredibly fast, diminished into a light orange color and disappeared.As I was walking my golden retriever down the golf course, a light from the sky draw-ed my attention to look up. For a brief moment I glimpsed a very large blue light illuminating beautifully moving as fast as a shooting star. It was a little smaller than the moon, as it traveled for about 2 seconds it diminished quickly into a light orange color and in a flash the light was gone. However for a brief moment I saw the object in the sky without the lights on then I lost track of it in the darkness. They were airplanes in the vicinity that had no similarity whatsoever to what I saw.
