--(6084) Bascom--discovery and notes:

Primary discovered 12 February 1985 by C. S. Shoemaker and E. M. Shoemaker from Palomar Observatory, California, USA, but identified in prediscovery observations to 1950. Alternate designations 1985 CT, 1992 BM1, 1978 EC6.

Secondary announced 6 February 2006 by D. Higgins and P. Pravec, Ondrejov Observatory NEO Photometric program based on lightcurve observations from 29 December 2005 to February 2006.
