I stepped out into my backyard and turn to the left. (nw). in the distance, rather low in the sky i saw bright lights, about 20 feet long and it was the lights coming at me, mayb 70 feet high. ii stood in my yard and i watched it till i came right above me. it was huge (20-(30 ft circumference ) round circular and i could see right through it i could see inside to like a cockpit area where there is like maybe a command center and then it turned to the left (east) and it just slowly left. none or little sound.
