Bodiam Castle - Orb #2 - Look up, and to the left, underneath the window on the opposite wall to where I'm taking the picture. The light on the right is cast by the sun shining through the window on that side, but there's no way that the light would be cast that far to the left, and the shape of it is all wrong for a window. You might need to save the pic to your documents if you wish, which is fine by me, then zoom in to it.
