Pozanenko (IKI) report on behalf of larger\nGRB follow-up collaboration:\n\nWe observed the field of SGR 1935+2154 triggered by Swift (Barthelmy et \nal., GCN 19430; D'Avanzo et al., GCN 19433) and Fermi (Yu et al., GCN \n19434)  with AS-32 (0.7m) telescope of Abastumani Observatory starting \non May 16 (UT) 23:26:26. We obtained several unfiltered images of the \nfield. We do not detect any source within XRT error circle  (D'Avanzo et \nal., GCN 19433).\n\nPreliminary photometry of the field is following\n\nDate       UT start   t-T0     Filter  Exp.
