This was a weird cloud or something.

If you did not see this head over to Perfect Day Duluth blog and look at the two shots they have up,http://www.perfectduluthday.com/. I saw the circle as just a plain circle at one time in the sky and thought it was a bit odd. I did not see the second pic some one got and then posted on PDD.

I did however notice this circle changed many times. It was one very odd occurrence. Do you have any thoughts on this? Please lets be realistic here.
