12447 Yatescup           Discovered 1996 Dec. 4 by Spacewatch at Kitt Peak.
The Yates Cup is a trophy awarded in the autumn of every year to the winner of the Ontario Universities Athletics football championship. Founded by Henry Brydges Yates of McGill University and first presented in 1898, it is the oldest football trophy that has been contested continually.
