I was driving northbound M6 and I saw the light in my right hand corner of my windscreen appear. The light was larger than air craft and also just appears then moved downwards in an odd gradient (that I haven’t seen from aircraft before). It was quite bright as in noticeable like you’d notice the moon (but not as big) but to my eyes slightly green. When it moved it had a tail and resembled your drawings in the examples. It disappeared before it hit anything or was masked by trees or buildings. It was too high in the sky for it to have hit anything or gone behind something. I didn’t hear a noise. I remember thinking if it was aircraft it was going to crash. But it just vanished. 21:40ish 18/02/21
