Bright triangle shape with iridescent "panel" type tail.I went outside before retiring for the night as I usually do to look at the stars. It was clear, no moon, no wind. Out of the corner of my eye I saw a bright object. When I looked at it, it was something I had never seen before. At first I thought it was a big meteor entering the atmosphere, but as I looked, it appeared to be about 500 feet up, and about 1/2 mile away, and about the size of a small business jet. It had a brilliant white ball of light at the front, and a 3 or 4 panel-like "tail" sections attached to it. The sections were distinct from each other, they were iridescent radiant colors in red, green, and blue and were roughly 6 times the length of the "head". It traveled smoothly from south to north, silent, and very steady. It looked very similar in shape to the Teston (Kent), UK/England, sighting of Saturday, August 13, 2016. I am an amateur astronomer, can identify most aircraft, and can tell the difference between n! atural occurring phenomena and a solid object. It was truly something like I have never seen before. It was awesome!
