Saw circle shaped object with green and red lights flying fast at different altitudes

Me and my dad were standing in the parking lot of our motel in Moab Utah when I noticed a weird circular shaped object with green lights around the outside and a red light in the middle of it. It was at very high altitude and not moving much at first. Then it went much lower and flew around over us going back and forth as far as we could see, sometimes it just stopped and hovered then accelerated fastly, it flew straight up and down sometimes, it made no noise and had no Jetstream. The green lights seamed to start from the middle and flash out towards the outside and it had a red light in the middle that flashed on and off. It flew around about 10 minutes then it was gone.
