Discovered on 14 August 1985 by E. Bowell at Anderson Mesa.
George W. (“Wes”) Lockwood (b. 1941), an astronomer at Lowell Observatory since 1973, is an expert on high-precision photometry. Central to his research has been a decades-long study of the seasonal variability of Saturn VI (Titan), Uranus, and Neptune, as well as activity cycles in the sun and solar-type stars.Naming citation (20090209/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
