It's was traveling horizontally and had a long comet type tail as it moved across in front of me and behind trees. The entire ball and tail were extremely pristeen white. I've never seen anything like it. It moved fast and I didn't have time to take picture because trees blocked my view after it moved a second or two and when visible again, it disappeared quickly. I don't think it was more than three seconds. I jumped out of car and took about four steps to the road and barely saw it's end. It was a beautiful experience. I know the time because I text a friend just afterwards.
