A blue orb taken in Wisconsin, USA

Recently, an American has found a mysterious and luminous orb on photos taken by his daughter, on October 3, 2013, in the State of Wisconsin. This UFO was a perfect blue circle flying in the sky.

Witness statement:

Not sure what it is these images were seen as I was going to delete landscape photos taken by my daughter months earlier. I was going to delete them from many photos or as I was deleting photos and something looked peculiar so I blew up area of photos that had these things and can't explain what they are so I'm sending them to you. They were taken with iPhone 4S they two photos with orbs in sky and one in grass in day time and another rectangular cloud like or silver box shaped effervescent with antennae . If you call I can email shots from phone if they don't appear or this attachment doesn't pick them up?
