Photographed an unidentified flying object

Took a photo of the church at Camp Malo, Colorado. Later, while looking at my photos, I noticed something strange and unusual in the sky above the church cross that I can't identify. I spent 30 years in the Navy and saw a lot of very interesting things flying into and out of the ocean and across the sky. I also worked a lot with helicopters and jets and this doesn't appear to be either. I didn't see this object when I was taking the photo, and it doesn't appear in any of the other photos of the church that I took. When I zoomed in to get a closer look, it almost looks disk shaped with a rectangular light on top.
