26283 Oswalt           Discovered 1998 Sept. 17 by the Lowell Observatory Near-Earth Object Search at the Anderson Mesa Station.
Terry Oswalt (b. 1952) is an American astronomer working in the fields of stellar and planetary astronomy. He has led or participated in observing campaigns for numerous occultations involving the Moon, planets and minor solar system bodies, including one of the first determinations of the size, shape, and density of 1 Ceres.
