Night time - could not see structure of ufo only the lights 2 flashing white lights on either side (slightly blue/green tinge) and 2 red lights top and bottom

flew towards us and then rolled over 90 degres as if to turn but just stopped and hovered briefly before fly back in the direction it had come from - was some 200 to 300 ft from the ground - was completely silent and approx width 60 to 100ft maybe larger

as the ufo turned (if a plane it would have flipped its wings one straight down and the other straight up) it hung in the sky and turned slowly on its axis. if the light had been better we could have seen the structure but the sky was very dark as was the ufo - if indeed my mind could piece together is was either prism or a classic disc shape distance between white lights 60 to 100 ft, The red lights were approxamitely 1 fifth of the span
