Very oddly even though this sort of thing should fascinate me, I am a scientist who works for Manchester university, I saw the object was not in the least5 scared or interested. I looked at it for a very sort time and carried on home with my shopping, not even looking back to see if was still there. Only around and hour later it struck me as odd and i nipped back out to see if there was anything there, there was not. The whole thing is rather odd, have you heard of this reaction before? Any other reports from the same time, place. Thanks Gary
