Silver/metallic toroidal object seen tumbling northbound during daylight.

I'm an amateur astronomer and I was setting up my gear just before sundown. When I glanced up at a plane that was leaving DIA, I noticed something else (naked eye) just north of the plane at a slightly higher altitude (~20k feet). It looked like a shiny disk and was moving slowly due north. I grabbed binoculars to get a closer look and I was able to see the object very clearly. It wasn't a disk but rather toroid in shape and metallic silver. It was tumbling as it moved north. In diameter I would say it was approximately 100-200 feet. The best description I can give would be a 100 foot diameter silver wedding ring being tossed in slow motion. I grabbed my partner and gave her another pair of binos. We just watched it for about 15 minutes until it was too far away to see with much clarity. Because of its silver coloration I thought it might be a mylar research balloon of some kind, but I can't find any reference to such a thing online. It had no visible lights of propulsion.

Hello,

I submitted a report last week regarding a sighting I experienced in Broomfield, CO on August 9th. I posted the wrong date for the sighting as it actually occurred on Saturday August 8th. I'd just like to make the change in case anyone else witnessed the event on the same day.

Thanks,
