Camping out watching stars, shape seemed to "materialize" directly overhead near cygnus over a period of about one half second, and as soon as it did, went from stationary to incredible speed with noacceleration and dissapeared behind roofline of adjacent house. travelling directly north. & or 9 lights connected in a acute triangle/chevron/v shape, with one leading light, and the leg closest to me being shorter than the other by one light. no lights defining rear of triangle. no sound, object seemed to be very high, either at jetliner altitude or above atmosphere even. the size was about the width of two fingers on a hand held at arm's length and the lights were as bright and about the same size as a top-magnitude star and although white in color, appeared in comparison to be a little yellower than the stars. most definitely not a firework, flock of birds, weather balloon, satellite, space x launch, swamp gas, hallucination or otherwise. completely sober.
