9460 McGlynn           Discovered 1998 Apr. 29 by JPL/GEODSS NEAT at Haleakala.
Named in honor of Thomas A. McGlynn (b. 1956), currently the chief archive scientist for the High Energy Science Archive Research Center at the Goddard Space Flight Center. He has played an instrumental role in developing archives and analysis systems for many satellites. His research efforts include studies of diffuse \gamma -ray emission and emission from active galactic nuclei, as well as n -body calculations of the effects of interacting systems. He has developed the SkyView virtual observatory and the SkyMorph web site, which allows Internet users to access imagery and object information from the NEAT project database and to search for moving or variable objects therein.
