I went out on my deck to bring my dog inside because she was barking. While waiting for her, I looked up at the clear night sky. I noticed two objects with blinking lights, and watched them for a while because they moved together at the same speed, in the same direction, which I had never seen before. They were higher than the commercial flight planes, but not as high as satellites. After the closest one started to move out of view, I noticed two small white (like stars) lights moving much higher in the sky. They made 2-3 tight circles around each other, and then moved in unison along the same plane, in opposite directions. The farthest one faded out of view, but closest one appeared to become stationary, like a star, and didn't move again for as long as I watched. I am a recently retired nurse, and have never seen anything in the skies like it before. It was the circling of the two lights and the fast and uniform movement in opposite directions that made me want to report it.
