(IPN\n643, GCN 2173) with the AT-64 telescope of Crimean Astrophysical Observatory\n(FOV =53x35 arcminutes).\n\n46 x 120 sec unfiltered images cover   ~75% of  the error box. The images\nwere obtained  between Apr. 26 UT 18:28:33.94 and 27 UT 01:33:05.92, i.e.,\nin 26.66 - 33.75 hrs after burst. The limiting magnitude (3 sigma) is about\n19.5 for all images. Visual comparison with the DSS reveals no optical\ntransient.  (The coverage  figure can be found in\nhttp://grb.rssi.ru/GRB030425. All frames marked in the figure were obtained\nfrom 2  to 5 times in different epochs.)\n\nDetailed comparison of the images is underway.",
