It appeared to be a large, round object, motionless, at an extreme altitude..

During a family gettogether, one of our guests notice an object almost directly overhead and called everyone out to see. After I saw it, i got out my full frame DSLR with a 150 - 600mm lens. I laid on the ground, zoomed out to 600mm, held the camera as steady as possible and took the image. After several minutes of observation and no apparent motion, we lost interest and returned inside our home. Since the recent coverage of the "spy" balloon, I realized that the object we saw bared an uncanny resemblance. The images include the original and 2 cropped.
