Is it Possibility of UFO...!!!

This strange photo was taken by Dr. Dave Oester (Author of the ghost hunting formula in Jerome, AZ), who was taking photos of the sunset effects on the local cloud formation. While viewing this photo, Dr. Sharon noticed the strange airborne anomaly on the left side of the photo. When this was blown up and cropped, the anomaly appears to be saucer shaped and does not correspond to any aircraft shapes or shapes of flying insects. No wings are visible. This was taken at sunset without flash. The reason the foreground is blurry is that the camera focus was set for the distant clouds, and not for the foreground. The camera was the 8 MB Sony Cyber-shot DSC T-70 using Super Steady Shot.

Was this strange flying anomaly what is called an UFO? You be the judge.
