GALAXIES IN THE FIELD OF GRB 021004

I.V.Sokolov, Yu.V.Baryshev, T.A.Fatkhullin

Results of the B,V,R,I investigations (counts, photometric red shifts, etc.)
of the field of size ~ 4\'.3 x 4\'.3 centralized at the host galaxy of GRB
021004 are presented.
Observations were fulfilled with the BTA/SCORPIO.
The catalog of galaxies found in this field includes 240 objects for which
the signal/noise ratio is more than 4 in each filter. This constraint
corresponds to the following limit stellar magnitudes: 25.5 (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 were
determined. Galaxies with a possible broad absorption at 2200A (in the rest
frame) were selected.
