11713 Stubbs           Discovered 1998 Apr. 25 by LONEOS at the Anderson Mesa Station of the Lowell Observatory.
Christopher Stubbs (b. 1958), of the University of Washington, has pursued a variety of projects in experimental physics and observational astrophysics, including searching for dark matter, measuring the rate of expansion of the universe with supernovae and testing the equivalence principle.
