9560 Anguita           Discovered 1987 Mar. 3 by E. Bowell at the Anderson Mesa Station of the Lowell Observatory.
Claudio Anguita (1930-2000), an astrometrist at the Universidad de Chile, was critically helpful during the establishment of the Cerro Tololo Interamerican Observatory, forging links between AURA and the Universidad de Chile. He was an IAU Vice President during 1994-2000. The name was suggested by F. Vilas.
