23648 Kolář           Discovered 1997 Feb. 1 by L. Šarounová at Ondřejov.
Czech amateur astronomer and telecommunication engineer Jan Kolář (b. 1936) served for decades as chairman of the Optical Group of the Czech Astronomical Society and was elected an honorary fellow of the Society in 2001. He constructed "Bikukr", a pair of telescopes for high-quality deep-sky visual observation.
