15399 Hudec           Discovered 1997 Nov. 2 by J. Ticha and M. Tichy at Klet.
René Hudec (b. 1951), an Ondřejov astronomer who works in high-energy astrophysics, especially on \gamma -ray bursts, has designed spacebased and groundbased experiments. He established the European Observation Network for GRB optical counterparts.
