We were driving in complete darkness and the initial flash was so bright. I was in the passenger seat and instinctively turned my head to the right and back an saw the fireball shooting west/northwest. We heard a big boom. I just remember how bright fluorescent green it was. It lasted 1-3 seconds after the initial blast.
