The airport rotating beacon was lighted up but not rotating; there is no NOTAM for the airport to this effect.  Approximately five days earlier on a flight to 9V9 [Chamberlain Municipal Airport] the airport beacon was not working at all.  I notified ATC Center via comm radio and the Controller explained that their Supervisor would call the airport Manager about issuing a NOTAM.  There is still no NOTAM or operational rotating beacon for the field.
Pilot reported the airport rotating beacon is out of service at 9V9 airport and there is no NOTAM.
