Remarks I only saw a smoke trail, it looked like object came from sky, made a loop and continued down or toward south. Trail did not reach the ground. Trail was thinner higher, thicker lower or southern. Trail Ended high in sky. It was very bright, sky was dark and clear, some small clouds appeared dark compared to trail. Perhaps it was high enough for Sun, which already was set, to shine on it.
Terminal flash
