Weather
We were cruising along when we experienced moderate to severe turbulence. The aircraft was temporary out of control and we lost about 800 feet in altitude over a period of about 10 seconds. The controller noticed that we had lost altitude and gave us a descent to FL450. The remainder of the flight was uneventful. Possible clear air turbulence. If we could get more pilot reports from the altitudes that we normally fly at that would be helpful. We did let the controller know that it was an extremely rough ride at Flight Level 470.
CE-750 Pilot report possible clear air turbulence resulted in temporary loss of control.
