(17941) Horbatt Main-belt Asteroid
Discovered on 6 May 1999 by R. A. Tucker at Goodricke-Pigott.
A skilled mechanical craftsman, Paul Allen Horbatt (b. 1946) has contributed greatly to the development of the instrumentation at Goodricke-Pigott Observatory, near Tucson, where this minor planet was discovered. His familiarity with detector enclosures and vacuum seals greatly speeded the fabrication of the instruments.Naming citation (20010309/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
