Blue blur UFO snapped near Hatch, Utah

On May 13, 2015, a father and his son made a road trip somewhere in USA. While they arrived near the little town of Hatch (Garfield County, Utah), the son sighted something in the sky. So the father took picture. On this photo, we can a mysterious blue blur UFO… What is it?

Witness report:

We were traveling north on hwy 89 near Hatch Utah. My son who is autistic and rarely speaks unless he has a question or gets excited was sitting in the rear passenger side of our vehicle. He says "dad look, dad look" I thought he was just excited by the cloud formation as he is enamored with clouds and weather. I was in the front passenger seat, we had the camera in the center console because we were shooting pictures on the way to Red canyon. I lowered my window and took the pic. I tried to reframe a second shoot but must have panned the camera and just got a blurred imaged. When I went to review the shot with him I noticed a blue blurred oval in the picture. Did not "notice" the blur when I went to take the picture.
