Abstract
We observed the field of the GRB 190613A (Ambrosi et al., GCN 24798) with RC-36 telescope of Kitab Observatory and AS-32 of Abastumani observatory . We do not detect the optical afterglow (Ambrosi et al., GCN 24798; Zheng et al., GCN 24801; Lipunov et al., GCN 24803). Preliminary photometry of the field is following.
