49350 Katheynix           Discovered 1998 Nov. 27 by W. R. Cooney, Jr., at Baton Rouge.
Kathey Nix (1953-2003), amateur astronomer extraordinaire, was manager of theaters for the Pink Palace Museum, Memphis, Tennessee, and a founding member of SLO, the Society of Low-Energy Observers. Her enthusiasm and selfless dedication to amateur astronomy and to her many friends will be sorely missed.
