We observed the field of the Swift Swift GRB 130603A (Melandri et al.,
GCN 14731)with AS-32 (0.7m) telescope of Abastumani Observatory on Jun.
03 and Jun. 04. We obtained several unfiltered images of 300 s and 180 s
exposures. The afterglow (Melandri et al., GCN 14732) is well detected
in combined images in both epochs. Preliminary photometry
