it changed but generally looked like an egg shape/sausage shape- it had a random greeny/yellow flashing light - it looked as though it had some rays of light as it was so bright - you know like when you have tears in your eyes and look at something bright

it hovered for ages - we followed it up through Sheep Walk in shepperton (we had the best view of it here) we headed towards chertsey and as we approached Chertsey bridge it sped off suddenly and we lost it. We drove ona bit trying to see if we could see it through the hosues, nothing - we turned around on ourselves and went back to where we had seen it best! It was back in the sky but further away from where we'd seen it before. we carried onw atching it - I had goosebumps and then suddenly like a blink of an eye it shot off and we never saw it again! It was so cool!
