37859 Bobkoff           Discovered 1998 Mar. 23 by P. Pravec at Ondřejov.
Despite shooting through the urban skies of Denver, CO, and around trees and houses from his apartment balcony, Robert Koff (b. 1943) has produced numerous high-quality lightcurves for minor planets and eclipsing binary stars. His work is a testament to perseverance, dedication and the power of CCD imaging.
