I noticed this bright orangey white light in the sky but as driving on a motorway was unable to take video with a phone etc. so checked the dashcam footage after. It wasn't far from Heathrow airport so considered a plane but it didn't seem to move and seemed too bright. A helicopter wouldn't create such a bright large light at that distance I wouldn't have thought. You can see how it shines through a number of trees. Also it seems to just materialise whereas a plane would have had the lights on the whole time. I ruled out the moon or a star as too big for a star the sky was clear so the moon wouldn't just appear in that way. Fireworks or a Chinese lantern wouldn't just appear like that and stay in the sky either, especially as bright as that. My only conclusion was space debris or a meteorite although very slow moving if at all and no stream or tail as such. Either that or a UFO....?
