I have never seen a fireball before, but have seen several "shooting stars". This was the largest (by far) and brightest thing I've ever seen in the sky at night as far as I can recall. It was hard to say the colors but I vividly remember green at the back of the ball and running through the trail it made. But it was so quick because I just saw the light then turned my head so it may have been there longer then the few seconds I saw. Still I have never seen anything like that.
