49987 Bonata           Discovered 2000 Jan. 3 by L. Tesi and G. Forti at San Marcello Pistoiese.
Italian aerospace engineer Diego Bonata (b. 1968) has promoted laws for the control of light pollution and energy saving through the Cielobuio Association, of which he is president. At the Carl Sagan Observatory in Brignano Gera d´Adda he has developed new environmentally compatible technologies for lighting engineering.
