66151 Josefhanuš           Discovered 1998 Oct. 16 by P. Pravec at Ondrejov.
Josef Hanuš (b. 1983) is a Czech planetary astronomer. He has worked on modeling rotation states and shapes of small Solar System bodies using the technique of rotation lightcurve inversion, and on their physical modeling using also infrared observations, stellar occultation data and adaptive optics observations.
