20254 Úpice           Discovered 1998 Mar. 21 by P. Pravec at Ondřejov.
Úpice is a small town in northeastern Bohemia. A public observatory was built there with the help and support of almost all the Úpice residents and has operated since 1959. Its main activities are solar astronomy and astronomy education. Meteorological, ecological and seismic measurements are also made there.
