Driving at night near the Northern California Coast - six orange orbs in the skyWitness one - I was in the passenger seat of a car when I saw six orange orbs in the sky. They appeared to be floating slowly. Before the driver could pull over, four appeared to get further away (into space) and changed their color to blue, looking like any other star in the sky. Witness two - I was driving when witness one alerted me to the orange lights in the sky. By the time I was able to safely pull over and look, only two lights remained. The seemed to be moving slowly or they were a far distance away. One seemed to grow bigger as it got "closer." Suddenly one disappeared (like the other four), then one reappeared shortly after quite far from where the other disappeared. The remaining orb of the first two looked as if it was disappearing, but then it just changed to a bluish color that matched the night sky and made it look like a star. The other orb moved slowly and then shortly disappeared after the other one.
