R. Hudec, L. Sarounova (Astronomical Institute Ondrejov), M. Tichy and J. Ticha (Klet Observatory) report: We have obtained 3 CCD images (unfiltered, V and R; the integration time 3 x 180 sec) with the 65 cm telescope of the Ondrejov Observatory at April 25.90 UT, and 12 unfiltered CCD frames (total integration time 780 sec) with the 57 cm telescope of the Klet Observatory at April 25.95 UT. Each of the images covers the entire error circle of GRB000424 (Piro et al., GCN #644). Comparison with the DSS reveals no new objects brighter than about mag V = 19.6 within the BeppoSAX WFC error box. This message may be cited.
