How cool. I personally have never witnessed a fireball. I hope to some day. :-)

It was the second best I'd seen (out of two). The other one I saw was last year during the Leonids. It was a green, pupil-contracting splash in the low eastern sky over a hazy, light-polluted Philadelphia. Despite the bright sky, the trail it left in the sky glowed like a neon tube for almost a full minute. If I'd seen it with a dark sky, or if it had been overhead rather than near the horizon, it probably would have knocked me on my ass.
