Pozanenko (IKI)  report on \nbehalf of larger GRB  follow-up collaboration:\n\nWe observed the field of SuperAGILE GRB 091010 (Donnarumma et al. GCN 10004) \nwith   Shajn telescope of  CrAO on Oct. 12 between  (UT) 16:55:18 - \n18:09:40. In the XRT error circle  (Margutti  et al. GCN 10006)  we detect a \nsingle object at coordinates (J2000) RA:  19 54 39.80 Dec: -22 31 04.71. The \ncoordinates of the object coincide with OT candidate reported by Rossi et \nal. (GCN 1008).\nThe photometry against nearby USNO-B1.0 stars (0674-0991940 RA:19 54 39.26 \nDec: -22 31 29.7 R=18.18, 0674-0991922 RA:19 54 38.07 Dec: -22 31 12.4 \nR=17.27)   is following:\n\nT0+     Filter, Exposure, mag.,     err.\n(d)                (s)\n\n2.62   R     71x60     22.40 +/- 0.17\n\nOur photometry confirm the absence of variability of the OT candidate (Rossi \net al.GCN 1008, Guidorzi et al.GCN 10027).  However the object looks like \nextended in E-W direction, and can be a candidate in a host galaxy of GRB \n091010.\nThe combined image can be found in \nhttp://grb.rssi.ru/GRB091010/GRB091010_091012_R_ZTSh.gif",
