Cigar/Circular object hovering in sky and moving strangely

I went outside to see the jets flying by. I saw two fighter jets flying northeast. The sky was clear with few clouds. Looking back towards the west I saw a dark brown cigar shaped object. I looked away to see if it was my eyes, and it was still there. It was hovering still. It changed to a circular shape and began moving north in a horizontal motion. It paused again and hovered still. It began moving horizontally north again and I lost it in the tree line. It did not move like a plane or a bird.
