I was driving home from work on A303 heading towards picket twenty as I came round the motor way bend it appeared over the car and I watched it as it fell behind the tree line. It looked like an falling arrow as it headed towards the ground with bright green coming off each edge of the arrow points at the front diagonally going out from tip of the arrow and there was a duller orangey red sparkling trail coming off the back much longer and narrower than the green flashes. It was beautiful and definitely the largest meteor ive ever seen. If it gets found or if anyone manages to find it please email me back id love to know what happens! Hope my account helps.
