UFO OVER ONTARIO, OREGON

I had just left the state park north of Ontario, Oregon and was just crossing over I-84 Highway when I noticed a cool cloud formation, I usually stop to take these kind of pictures besides sunsets.
I pulled off the side of the road and put my window down to take a picture of the cloud formation.  I took only one picture then I got my window up and continued on my way into town and home.  When I got home and parked I looked at the picture and thought it looked cool.  I happen to notice a black dot way over on the bottom left of  the picture.  I expanded the image and noticed it looked like a disc tilted and facing my way when I had taken the picture.  I was excited to have captured this.  Looks like a disc to me.  You be the judge,I  will be sending the picture email with this report.
