Was driving mid morning and saw 6 spheres flying together and moving around each other. They were shiny and silver looking. No protrusions, just spheres. They would be in the formation of a V, then 2 on each side would move around the sides to come in the front and they held that formation for a sec then moved around again. They were not stationary but kept moving in a small general area. They also each had a hazy halo in a circle around them. Then they disappeared
