Not what OP saw but a super cool photo by billyhoag1
“Dear PoPville,
I was wondering if you have gotten any reports of 5 orange round shaped “lights” moving pretty low in a straight formation above the NW DC area. They aligned side by side and then vanished. I was with 4 girls on my friends rooftop and me and another girls saw the lights as well. We were on a roof top on Westminster looking over to the Shay building when we saw this.”
