Scientific paper

The error box of the gamma-ray burst source GRB 790325b and its neighborhood were investigated on about 5000 plates taken at the Bamberg, Ondrejov, and Sonneberg Observatories in the years 1928-1986. The total monitoring time covered by these plates corresponds to 0.82 yr. No reliable optical candidate has been found inside the gamma-ray error box, the only possible exception being a faint transient image (0.6 mag above the plate limit) found at the edge. However, these (and possibly five) optical transients (OT) with durations below 10 min to 1 h were found at the same position, located 5 arcmin away from the center of the gamma-ray error box. The 1-sec photographic magnitudes of the main flashes detected in years 1946 and 1954 are, 6.1 + or - 0.5, 4.0 + or - 0.5 and 3.8 + or - 0.5. These transient images were studied in detail.
