14012 Amedee           Discovered 1993 Dec. 6 by T. Seki at Geisei.
Amedee is a small uninhabited island 30 km west of Noumea, New Caledonia. The huge lighthouse, said to have been built by Napoleon III, is the symbol of the island. The discoverer of this minor planet observed 1P/Halley from this island in 1986 April.
