Pozanenko (IKI) report \non behalf of larger GRB follow-up collaboration:\n\nWe observed the field of the Swift GRB 140610A (Evans  et al., GCN \n16375) with Zeiss-1000 (East) telescope of Tien Shan Astronomical \nObservatory starting on June 10, (UT) 16:49:37, i.e. 18 minutes after \nGRB trigger. We took several images in R-filter. Within enhanced XRT \nposition (Evans et al., GCN 16388) we do not find any new source neither \nin the first image nor in a stacked image.\n\nDetails of the photometry are following:\n\ndate        UT start   t-T0       Filter  Exp.
