Pyramid formation lights above Matthews, NC.Just after midnight, I went out into my backyard to have a cigarette and I saw 3 lights in the sky, forming a sideways triangle or pyramid. At the front were two lights, nearly vertical and then about 300ft behind them, a single light, forming the point but at the rear. The three lights moved in unison, and at the same speeds. The lights were white with a bluish halo.I immediately called my wife and 8 year old daughter out and they both witnessed the event. I tried to capture it on my cellphone but was unable to get anything clear.Once the lights disappeared behind my neighbors roof, we lost track of it.
