I've seen a UFO ...
Coming out of my brothers house, I was going towards the car when I noticed a orange orb floating at a constant speed across the black sky, fortunately my brother was there to notice.
Orange orb surrounded by a orange haze (fog) of consistant width, no sound, constant speed, about the height of a block of flats (UK size). Pulsing from the centre, there was no aircraft lights, e.g. white or red. Direction Walthamstow towards the City.
Size of the object, about a mini-car in width.
Let me know your thoughts,
