silver ball with a yellow ring at the mid piont of the sphere hovering and then departing south at a fantastic rate.My father was doing yard work and I was playing somewhere close by when he drew my attention to a silver ball with a yellow ring encompasing it. It hovered for a short time then headed south at a fantastic rate of speed. no sound, no exhaust, no lights, no windows, no landing gear just the yellow ring at ate midpoint of the sphere.((NUFORC Note: Date is approximate.
