SIGHTING REPORT UFO sighting at Wolverhampton, West Mids. UK

All I could see was a very bright light. It could have been round but the light was so bright the true shape was probably hidden. Everything is orange outside due to the street lamps reflecting off the snow. This object was emmiting its own strong colours.
The angle I saw it come over the roof meant I did not really see it standing next to anything to make a good comparison. Anything from a large van to a small aeroplane. Could have been the height of low cloud formation.

It was a strange object full stop. It was very fast. It zipped in like a fly and zipped out just as fast. The object seemed to be clearer when it was hovering and just a blur when it went off into the distance. It did so quite quickly due to some clouds. Also like a camera flash, Ive still got the after image in my head....

The after image seems to be clear. If I close my eyes I can see some shape to the object, just some hazy lines. There is a trail coming off the object in the direction it had come and a faint one in the direction it was going.

I seem to have spent more time on the boiler than I should have. It should have only take 3 minutes, but I seem to have taken much longer. Im sure I only saw the thing buzz by pause for 2 seconds and then zoom off over a period of 5 seconds. Now it seems longer. I dont know im cold and confused. I also noticed that the air temperature was warm, it did not feel like there should be snow on the ground. Whats this damp patch on the back of my head? I did not feel anything at the time. If anybody out there wants to follow it up do your own research. Ive got a life to get on with. At the end of the day I am happy to stand back and say "WOW!" and carry on. No I will not take part in any more discussion of this subject. It has already taken up too much of my precious time.
