Discovered on 9 October 1980 by Shoemaker, C. S., Shoemaker, E. M. at Palomar.
Jewett Castello Gilson (1844-1926), Californian teacher, author and superintendent of schools, was determined to secure an astronomical observatory for the schools and people of Oakland. In 1883 he found a donor to fund what became the Chabot Observatory. The name was suggested by the Eastbay Astronomical Society.Naming citation (20000523/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
