UFO ?

I took this random photo out at the dump today around 1:30pm. The bottom picture is the original and the middle one is with enhancements of course. In the right lower side you can see a raven but above and to the left center is something else. Too windy and cold to be a bug. As I did not see it at the time I can't tell the size but it appears to be disc or cylinder shaped. The top photo was also taken at the same time ( within a few seconds ) and shows that it was not a smear on the lens.
