10968 Sterken           Discovered 1971 Mar. 26 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Christiaan Sterken (b. 1946), an astronomer at the Free University of Brussels, has a particular interest in \beta Sct, \delta Sct and S Dor stars. He established the working group on Long-Term Photometry of Variables at the European Southern Observatory and was co-founder of the Journal of Astronomical Data (1995).
