GCN 31697) \nwhich is also detected by GBM/Fermi (Wood  et al., GCN 31702) with AS-32 \ntelescope of Abastumani observatory (AbAO) in   R-filter starting on \nMar. 06 (UT) 18:32:11. We  detected the  object at the edge (2.6 arcsec \napart) of the enhanced XRT position (Evans et al. GCN 31700). The object \nis also presented in Pan-STARRS   as a red source (objID \n193630053894966412, r=21.42, i= 20.70, z=20.54). Due to non-optimal \nseeing we cannot discriminate a possible optical afterglow from the \nobject.  Preliminary aperture photometry of the object is following\n\nDate������������ UT start���� t-T0������ Filter Exp.������ OT����  Err.�� UL(3sigma)\n    ��������������������������������������(mid, days)������ (s)\n\n2022-03-06 18:32:11����  0.02886�� R�������� 50*60����19.98 0.12 ���� 22.7\n\nThe R magnitude of the object seems to be brighter than R_mag deduced \nfor the object assuming the object is a star.
