strange shadow unexplained?

[mojo]

Please go to the 2:30 minute mark and help to explain this one. It might be a small bug on the camera or waterdrop but also might be an object shadow in the sky???

If you think of an extremely out of focus object -- it fits. If you consider that an object would have to be completely out of focus range - as in, the subject of the video image is distant scenery - to move out of the focal plane something would have to be extremely close to the lens. If we consider that something that close to the lens would have to be very small, insect or arachnid fits the bill perfectly.

99.999% confident it's something on the camera lens -- note how the object obscures cloud detail luminance -- a shadow from behind the cloud would not do that.

I've seen similar here in South London, day and night.
At night iv'e seen light patches that don't seen to be natural (I know that clouds can supposedly be self luminescent) I've even considered light coming up from ground/city features, but quite a lot don't fit the bill. There are often moving beams shining up from the ground, so i'm not fooled by them ;)

Who knows what really goes on behind/above them clouds.

In a place where I used to live I used to see a really freaky scene. In early evening on days where low cloud was present, I used to see the image of a window oping in the sky ).o
I investigated and found it to be a house window that was open in the evening, said wind used to be in direct line of car headlights while they where waiting at traffic lights :)
as cars moved off the image would change as if opening and closing.

So keep watching them sky's.
