19980 Barrysimon           Discovered 1989 Nov. 22 by C. S. Shoemaker and D. H. Levy at Palomar.
Barry Simon (b. 1952), a first-rate amateur astronomer, founded the Deep South Regional Stargaze in 1983 and has managed it since then. Now in its twentieth year, this event helps participants from many southern states observe under a dark sky. Simon has amassed a large collection of refractor telescopes.
