15817 Lucianotesi           Discovered 1994 Aug. 28 by A. Boattini and M. Tombelli at San Marcello Pistoiese.
Luciano Tesi (b. 1931) founded the Amateur Group of the Pistoiese Mountain in 1980. This later led to the construction of the Pian dei Termini Observatory. As director of the station, he has collaborated with the discoverers since 1994 in finding minor planets and following up near-earth objects.
