Ibrahimov (MAO), A.Pozanenko (IKI), V.Rumyantsev (CrAO) on\nbehalf of larger GRB follow up collaboration report:\n\nWe observed the error box of  short duration GRB051105 (Mineo et al. GCN\n4188) with 1.5m telescope of Maidanak Astronomical Observatory under good\nweather condition (seeing ~1.1). Set of  R images were taken starting on\nNov.5 (UT) 13:59, i.e. 7.6 hours after burst onset. The BAT refined error\nbox (Barbier et al. GCN 4194) is partially covered  (~70%). The second set\nof R images were taken on Dec.1 between (UT) 13:33 and 14:09.\n\nThe following R magnitudes of objects mentioned in GCN circulars\n4195,4196,4201,4199,4202,4203,4204 were estimated at mean epoch  of\nobservation (UT) Nov.5 14:17\n\n---------------------------------------------------------\nR.A.

GCN 4194) between both epochs of our observations. The\nphotometry of extended galaxy mentioned by Klose, Laux, & Stecklum (GCN\n4196)  and  details of the observations are following\n\nMid time,  Exposure, Galaxy,         Mag.(UL),Seeing\n(UT)          (s)     R(mag)\n\nNov.5 14:17  1380    18.211 +/- 0.022  22.1   1.10\"\nDec.1 13:51  1800    18.122 +/- 0.019  21.8   1.45\"\n\n\nUsing available at this time observations we cannot confirm possible\nre-brightening of the galaxy in the 2nd epoch. Detailed calibrations are\nnecessary and further monitoring of the galaxy would be encouraged. If\nconfirmed then it might be connected with SN associated with short duration\nGRB051105.\n\nThe stacked images of both epochs  can be found at\nhttp://grb.rssi.ru/GRB051105/.\n\nThe message may be cited.",
