I was driving due west when I saw the fireball. It became visible in the top left of my windshield (SW) and proceeded towards the horizon on the right (WNW). It was already quite bright when entering my field of vision from the top of my windshield. When arriving home two minutes later, a smoke trail was visible in the sky due south and parallel to the horizon/roof of my house. I have two additional photos of the smoke trail available. Highest exposure photo provided.
