RemarksWow, this was simply amazing to see, to give you an idea on the size, it was about as big as a cat if you were viewing the animal from about 7 ft away. Hope this helps. Kind regards, Andy.

RemarksThis was amazing to see, it was that big, it seemed at first like a firework rocket, cone shaped and bright emerald green with red sparks coming from its tail. Then when it went over the M1 the front split into 2 small red balls, and then it went out of view as if it had burned out. The best thing ive seen all my life. It looked to be only traveling at about 40 mpm from me and my friends perspective, that's why we thought it was a firework and dismissed as such. But when i read countless others had seen it, it gets even more strange. Please can someone confirm what it was.
