Brownish, bronze colored round or egg shaped UFO passed by. Silent and no change of course. Clear bright day. Brown bronze colored egg shaped, not perfectly round. Altitude guessing 4-5000 feet. Moving NE to SW at a steady rate of speed. Originally I thought it was a large bird riding the wind but it never flapped its wings or changed course. It took a few seconds for my mind to really grasp what it wasn�t before I could try and figure out what it was. Total time elapsed was about 30-45 seconds before the edge of the house restricted my view of it. No sound, no trail.
