Kouprianov (GAO RAS),\nV. Sokolov (SAO RAS) and A.J. Castro-Tirado ((IAA-CSIC Granada, Spain)\non behalf of a larger collaboration report:\n\nWe observed the field of the GRB081203A (A. M. Parsons et al., GCN #8595) \nin the Rc-band with the 6-m telescope of the SAO RAS in Caucasus. In total 15\n3-min exposures were obtained starting from 01:42 7 Dec. 2008 UT (T-T_0 =\n3.49 days).  We clearly detected an object at the position of the UVOT\noptical transient (M. De Pasquale and A. Parsons, GCN #8603).\nCalibration based on the SDSS stars yields the brightness of the OT as\nR = 23.94 +/- 0.13 (errors are statistical only). At the 3.2 +/- 0.2 \narcsec to the South-West from the OT position we also detect an extended\nobject with R = 22.74 +/- 0.07. For redshift of z=2.05 (N.P.M Kuin et al,\nastro-ph/0812.2943) it corresponds to ~26 kpc in projection (H0=71,\nOmega_M=0.3, Omega_L=0.7). It is unlikely that this object is a host \ngalaxy of the GRB081203A but redshift measurements are needed for certainty. \nFurther observations are planned.\n\nOur finding chart can be dowloaded from\nftp://ftp.sao.ru/pub/grb/GRB081203A/GRB081203A_OT.jpg\n\nThis message can be cited",
