Small dark UFO spotted over Arizona

On November 4, 2014, in the early hours, an automobilist went to work when he has noticed something of unusual in the sky, in Arizona. At first, he thank that it was a small cloud. But, after a few seconds, he realized that it was UFO…

Witness report:

I was just leaving for work, approximately 6:15am on Nov 4th, and as I drove along in the neighborhood (NE Mesa, AZ), the object caught my attention. I'm not sure why I even noticed it, but at first I thought it was a small cloud. It hit me, though, there was not a cloud in the sky. Maybe it was the contrast of a perfectly clear sky and then this shape. I watched it the whole drive out of my subdivision trying to figure out what it was. I don't believe it moved, but I was moving so not sure. It finally hit me that this might be a UFO, so I took a picture as I was leaving my subdivision. I didn't think to zoom in before taking it, so it's difficult to see unless you zoom. It's in the middle of the photo, about 2/3 of the way up. After taking the picture, I continued onto work, so didn't see what happened to it. There is nothing that is really spectacular about this sighting, except I can't let it go, I just can't imagine what it could be if not a UFO, hence this report.
