Mechanical cogwheel looking large objects behind the cloud.

The cloud formation were so beautiful that day. So I was taking many pictures to show people on my Facebook. While I was taking pictures, I saw a little brown spot in the sky. Later, I enlarge the sky picture with the brown spot in my cell phone to see what that was. When I enlarge the brown spot, I could see the Mechanical cogwheel looking objects behind the clouds. I am a housemaker and I came this mall for shopping. I parked my car at the parking lot and took the pictures at the parking lot.
It's not birds, airplane or lights. Does not look like satellite things or space shuttle. I would like to know the answer please.
