9822 Hajduková           Discovered 1971 Mar. 26 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Mária Hajduková (b. 1934), currently at the Astronomical Institute Comenius University, Bratislava (Modra Observatory), has been active in interplanetary matter research, mainly meteors---multicolor photometry and radiation (dependence of the color index on velocity). She educated a whole generation of astronomers in Slovakia.
