Turned off the lights outside to look at the stars and my boyfriend and I saw a strange boomerang shaped craft with what can only be described as a triangle that was barely reflecting from the moon. It was absolutely silent coming from the SW and it had no lights. The whole thing was cloaked in what looked like a white hue where it was bending light. At first I thought it was a fast moving cloud but I quickly realized it was something else. It wasn't an aircraft I've ever seen and with no lights and no sound we were completely stumped. It went in a straight movement but then it came back into our sight part and it did an interesting pattern like a falling leaf doing a loop d loop
