8323 Krimigis           Discovered 1979 Oct. 17 by E. Bowell at the Anderson Mesa Station of the Lowell Observatory.
Named in honor of Stamatios M. (Tom) Krimigis (b. 1938), head of the Space Department of the Applied Physics Laboratory of Johns Hopkins University and a specialist in solar, interplanetary and magnetospheric physics. Krimigis has been principal investigator or coinvestigator on several space experiments, including the Low Energy Charged Particle experiments on Voyagers 1 and 2 and the Active Magnetospheric Particle Tracer Explorers. He spearheaded the establishment of NASA's Discovery program, and his department is managing NEAR, the first Discovery mission.
