Every Fleet Academy has an Academy Bell. Usually these bells are replicas of famous bells. Cadet Har Hi rang the Terran- Asian Bell of the Newport Academy signaling they had won the Reagan Trophy.(1)
Ringing the bell every hour is a task usually given to a Cadet as honor duty.
There is a Bell Ringer Ribbon for this and is awarded to Cadets with outstanding results.
