11679 Brucebaker           Discovered 1998 Feb. 25 by the Near-Earth Asteroid Tracking Team (NEAT) at Haleakala, Maui, HI.
Bruce Baker (b. 1949) fabricated and installed the mechanical portions of the slip rings and assisted in the fabrication of many small mechanical assemblies needed throughout the upgrade of the 1.2-m Schmidt at Palomar.
