Observed a craft North of Colville over the mountain with the “C”

While star gazing as i do from time to time when I am unable to sleep I had been looking east to South to West ignoring the north. After several minutes I felt I had neglected the North for awhile. And honestly it almost felt like i was being watched.
Upon looking north I saw what I initially thought was a flicker of light however within a second I realized it was something else. As I lifted my bino’s up I watched the light transisition into a disk shaped object. When viewed through binoculars I saw a glimmer or some sort of shifting movement maybe.
I watched it briefly in shock both with the bino’s and with unassisted eye. It appeared stationary over the mountain approximately 100 feet above the “C” and almost centered over the cross. From my perspective the height could be off as my perspective in the dark was relational.
The light started as a small size of about 2-3 feet. However upon closer examination I realized it was indeed a disk shaped object. The disk appeared to be 50-75 feet wide and maybe 15 feet tall.
The disk initially was translucent and slowly appeared to be solidifying. It went from shimmering to being a solid object over a couple of seconds.
When I realized what it was I thought to myself to get a picture and as I had the thought I removed the bino’s and unlocked my phone for a picture. It then shifted back and forth in place stationary and as I was opening the cam app it flashed away very quickly.
