20433 Prestinenza           Discovered 1999 Feb. 14 by G. Masi at Ceccano.
Luigi Prestinenza (b. 1929) is a very active, appreciated and popular Italian amateur astronomer. A journalist by profession, he did impressive work to keep fresh the memory of important observers of the past like Cerulli, Schiaparelli and Maggini. He is president of the "G. Ruggeri" astronomical group in Catania, Sicily.
