While driving home, I observed 3 orange lights floating over the interstate.While driving home, I observed 3 orange lights in the sky. At first I only noticed 1 and it looked like the distant glow of a fire. As I continued driving however I noticed 2 others. I was driving east and the lights appeared to be moving very slowly in a southern direction. This was how I realized that they were not fires. Based on how their position relative to me changed as I was moving, I would estimate their position to be approximately 1 mile away and ½ to 1 mile in elevation. They appeared to be moving over the interstate. I observed the lights for about 5 minutes, until I passed beneath the interstate. Upon reaching the other side of the interstate, I looked back and the objects were gone.
