Hovering, spinning, shiny object in the sky.

Looking out my office window, at approximately 10:13am (Pacific), I noticed something curious in the sky. At first it seemed as if it was blinking or flashing. After watching it for a minute or two, and as I began filming it with my phone, it looked more like a metallic object catching sunlight. Also, as I zoomed in with my camera, there was a distinct appearance that the object was spinning. The object looked to be very high up – at, or most likely much higher than the commercial planes we often see. A few minutes after I stopped recording, the object seemed to elevate quickly upwards, then hover in place for a bit, then lowered again, and at one point seemed to move north/away from us. Eventually, after around 10-12 minutes, it seemed to move in a westerly direction, disappearing from site and into the clouds.
