78115 Skiantonucci           Discovered 2002 June 20 by S. F. Hoenig on NEAT images taken at Palomar.
Robert "Ski" Antonucci (b. 1954) is an astrophysicist at the University of California Santa Barbara, working on extragalactic astrophysics. He is best known for his spectro-polarimetric work on NGC 1068, which paved the way for the unification scheme of active galactic nuclei.
