1999-11-15 - Yuma, AZ - Circle

I awoke at approx. 5:30 am and was going into San Luis Mexico for dental work and saw a circular object in the sky.

I thought that it was a cloud but it was too perfect and there were no other clouds in the sky. It was as big a a very large house would be and perfect in shape and whitish in color. It was as if someone took paint brushes and painted a perfect circle in the sky and just left it there. And at one point I thought it might be con trails that just came together in a perfect circle but that would be hard to do. I have been a pilot and know that it would be impossible. I watched it for some ten minutes and then it was just gone. There was no sound to it at all and at that time of the morning there was no one out that I could see to confirm this with someone else. It has taken me so long to report this but I was away from home and didn't return until this evening. And there seemed to be some light going around the object but they seemed to blend into the object.
