Swimming after sun down about 9:15 pm. awaiting view of big dipper for any signs of neowise which would have been north east of my position in the pool. i kept looking up and turned around south east and viewed what i could tell a large ( half a foot ball field size ) circular transparent object ,i could make out the edges of the object. it took on the color of the sky ,grayish blue, and had a metallic shimmer that made it look transparent. there were three very dimmed lights ,no blinking mostly on the right side of the object. there were commercial planes that had been flying that night but obvious to the naked eye. this object had no noise and moving moderately fast. i stared at it for about 4 seconds as it seemed to fly over the next block /street in front of the house at 45 degree angle. it disappeared /vanish like it was cloaked perhaps. it was not a mylar ballon, no plan or helicopter, no drone, or fire workout nor a plastic bag.
