Triangular formation of lights in the skyWhen I and my friends left our house to go to a party I saw a triangular formation of lights in the sky. Better to say: an angular formation of lights because there were no lights on the "back side" of the object. There were 4-7 white lights on both "sides" of the triangle. One light was in the "front corner". The object made no sound. It made a circling motion. The axis of this motion was close to one of the "sides" of the craft. After ca. 2 min it vanished either by turning off the lights or disapearing behind the clouds or both. ( the sky was semi clouded ). The size of the object ( it's altitude was at cloud layer ) must have been that of a passenger aircraft at least. I don't remember if the white lights were blinking. It looked like this: ( not sure about the number of lights ) The "X" represents the axis of motion. O X O O O O O O
