I was outside at night to observe the ISS fly over as I do on occasion. It wasn't the best flyover as It was way north of my residence but I was able to observe it move from west to east. It was about five or ten minutes after this as I stood near my wife who was sitting on the porch, when I first saw the fireball as I was looking south southwest I was able to point it out and she quickly walked from porch and was able to see it looking south as it traveled east. Both of us exclaimed how we had never seen such an event. It was partly cloudy but we could see the fireball as it moved west to east and disappear briefly as the view would intermittently be obscured by a small cloud. As it traveled east we lost view because of a cloud.
