UFO?

Visited Broadway Tower today with Aliscotia and client Amy.  Got down on the grass and pointed up. Not until I looked at this in Lightroom did I see a curious image along side the tower - did I capture a UFO?
 
Anyway for those less concerned with extra terrestrial matters..

Broadway Tower is a folly on Broadway Hill, near the village of Broadway, in the English county of Worcestershire, at the second-highest point of the Cotswolds. Broadway Tower's base is 1,024 feet above sea level. The tower itself stands 65 feet high.  It was a beautiful day today to show off the Cotswolds to our new American friend.
