(31113) Stull Main-belt Asteroid
Discovered on 19 August 1997 by DeGraff, D. R., Weaver, J. S. at Alfred University.
John Stull has selflessly spent much time and effort to build the observatory at Alfred University from a telescope lost in an attic to arguably one of the best undergraduate observatories in the U.S. He built or improved five telescopes, including a 0.8-meter Newtonian that is the largest optical telescope in New York state.Naming citation (20020328/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
