Very strange circular object sighted over Wellsburg

On April 10, 2015, a family living in Wellsburg (seat of Brooke County, West Virginia) has seen a very shinny circle-shaped UFO. Intermittently, this object changed colors. What is it?

Witness report:

I was playing basketball with my two sons. I told my youngest to shoot the ball but he was fixed on the sky. I turned up to see what he was looking at and I saw a very shinny object in the sky. I immediately took out my camera phone and started taking pics. I took about 5 before I started looking at the pics. When I zoomed in on the pics it looked very different from what I could see with my naked eye. From my naked eye it looked like one sphere. When zoomed in on there were spheres inside the the main sphere they would change placement on the object as well. In some pics the object seems to be breaking apart into smaller pieces but still remained the same size to the naked eye. This event lasted for around two hours then it got very cloudy out and couldn't make it out any longer. There were around 6 people who saw this including my kids.
