--(15268) Wendelinefroger--discovery and notes:

Primary discovered 18 November 1990 by E. W. Elst from La Silla, but linked to observations from 1979. Alternate designations 1990 WF3, 1979 WA7, 1986 PO5, 1999 CD133. Name assigned 2008.

Secondary discovered from lightcurve observations by J. Oey, P. Pravec, P. Kusnirak, K. Hornoch, R. Stephens, S. Gajdos, L. Kornos, and V. Chiorny obtained 24 September to 9 October 2008 from the following sites: Leura Observatory, NSW, Australia; Ondrejov Observatory; Goat Mountain Astronomical Research Station, Yucca Valley, CA, USA; Modra Observatory; and Kharkiv National University.
