21802 Svoreň           Discovered 1999 Oct. 6 by L. Kornoš and J. Tóth at the Astronomical Observatory of Comenius University in Modra.
Ján Svoreň (b. 1949) is an astronomer at the Astronomical Institute of the Slovak Academy of Sciences, Tatranská Lomnica. He has worked on physical properties of comets and compiled a catalogue of the magnitudes of the long-period comets observed during 1861--1957.
