1 GALAXIES IN THE FIELD OF THE GAMMA-RAY BURST GRB I.V. Sokolov, Yu.V. Baryshev, T.A. Fatkhullin Results (counts of galaxies, photometric red shifts, etc.) of BVRI observations of the field of size 4'.3 x 4'.3 with the host galaxy of the gamma-ray burst GRB are presented. Observations were carried out with the BTA/SCORPIO. The catalog of galaxies found in this field includes 261 objects with the signal/noise ratio more than 4 in each filter. This restriction defines the following values of the limit stellar magnitudes: 26.0 (B), 25.5 (V), 25.0 (R), 24.5 (I). The exposure times were 3600s (B), 3600s (V), 2700s (R), 1800s (I). Photometric red shifts of these galaxies up to z ~ 3.5 were determined.
