11022 Serio           Discovered 1986 Mar. 5 by E. Bowell at the Anderson Mesa Station of the Lowell Observatory.
Salvatore Serio (b. 1941) teaches astronomy at Palermo University, specializing in x-ray observations and modeling of solar and stellar coronae. As director of the Palermo Observatory and president of the Italian Astronomical Society, he served as a gracious and generous host for the celebrations of Ceres' bicentennial.
