I was sitting in the hot tub looking at Orion the Hunter and noticed a line, more or less, of lights proceding in a NW-N direction, moving faster than a polar satellite, and somewhat dim considering the city light pollution. After a second or two the V-shape was apparent with five or more lights on the underside of each wing? of the craft. The V shape was wide, that is not cheveron shaped, and there was no sound associated with the sighting. It disapeared behind my house and into the haze in the direction of Boulder. The entire event took less than 15 seconds. This is my third sighting of an unidentified object and I knew exactly what I was looking at, although different than the first two.
