At 10:20 A.M. in Pecos, NM, I watched a large white orb UFO / UAP travel in a straight line across the sky. There were no clouds in the sky, it was perfectly clear. There were no other airplanes in the sky at the time of the sighting. The orb traveled quickly, leaving no trail, and was faster than an airplane I think. I took two photos as it moved. The object appears like an orb sitting within a disc possibly but it is blurry. There are dark spots equally spaced out in the photo allowing the observer to make out a crude object. In the second photo, the object appears more as a blur, kind of cloudlike. But there were zero clouds out that day. Also, an hour after the sighting, there were 9-10 airplanes out in the sky at the same time, which I found odd being that I usually see 1-2 at a time in my area. They were all leaving significant trails and were moving slowly compared to the UFO / UAP I observed. I am keeping the photos private until I can do some more research. For the rest of the day I felt mentally foggy. I can't stop thinking about what I saw.
