four lights moving east then suddenly westWas letting dogs outside and saw four lights to the south of town. They all moved in formation to the east, almost in the shape of a rectangle. My husband saw this too. Shortly after moving a ways, they switched direction quickly and headed west. Each light flickered right after the other, they were spaced apart too, quite a bit. They moved together to the west until I couldn't see them anymore. Never seen this before in my life. The way they flipped direction is unreal to me.
