While reviewing and editing town photos taken earlier in the evening, I noticed this object in the sky in the background. I didn't notice it at first in the original photo, it wasn't until I converted the image into a Contour image that the object appeared. Sure enough when I went back to look at the original photo, I noticed this little disc-shaped object in the sky above right. What is particularly interesting to me is that: in order for this distant object to have showed up in the Contour photo image (where light objects are reversed as black, and black objects are converted to light) indicates possibly some sort of magnetic field (dark matter?) may be surrounding the object. Not sure.I've included the original photo, a second enhanced photo, and the third Contour-image photo for your review.
