--(2006) Polonskaya--discovery and notes:

Primary discovered 22 September 1973 from Nauchnyj by N. S. Chernykh, but linked to prediscovery observations. Alternate designations 1973 SB3, 1966 VC, 1948 QH, 1941 SD

Secondary inferred based on lightcurve observations from 1 November to 7 December 2005 by Pray et al., Ondrejov Observatory NEO program.
