9115 Battisti           Discovered 1997 Feb. 27 by P. Sicoli and F. Manca at Sormano.
Named in memory of Lucio Battisti (1943-1998), innovative Italian composer and singer. He wrote many songs for himself and other singers, among them "Emozioni" and "I giardini di marzo". Beginning in 1973, he lived in a small village in the neighborhood of the observatory where this minor planet was discovered.
