I saw reflective object in the north sky that seemed to stay in a fixed position, silverish gray, odd shape.

Looking to the North from my back yard, I saw one high-altitude reflective object that caught my attention while talking on the phone. It stayed in a fixed position and seemed to be rotating or I could see what looked like a shimmer, or flash the color was silverish gray.
I live close to the Heber Valley Airport and could see and hear smaller planes at the same time, lower altitude and closer to my house - I do not believe this object was a Jet or Plane.
I should have stopped talking and tried to take better photos, but my friend was joking and making fun of me seeing a UFO. I would say it lasted about 8 to 15 minutes. I walked in the house ended my phone call and then went back outside, there was cloud cover by then and I could not find the object sadly I did not see it leave or get any other photos.
It's hard to see the object in the attached photos, you have to zoom in and look to top of the frame. I added a snip also hope that helps.
