Belkin (IKI) report on behalf of larger GRB IKI \nFuN collaboration:\n\nWe observed the field of  GRB 200115A (Cenko et al.,  GCN 26771)  with \nAZT-20 1.5 m telescope  of Assy-Turgen observatory  starting on Jan. 18 \n(UT) 16:55:27  in  r'-filter.   We do not detect the afterglow candidate \n(GCNs 26790, 26818) up to r'=22.8 (AB) and hence we consider the object \nfound in BAT error circle (Cenko et al.,  GCN 26771) as the optical \nafterglow of GRB 200215A.\n\nPhotometry of the field is following.\n\nDate       UT start   t-T0       Filter Exp.
