Pozanenko (IKI) on behalf of larger GRB follow up\ncollaboration report:\n\nWe observed error box of GRB061019 (Guidorzi et al., GCN 5728) with Shajn\n2.6m telescope of CrAO on Oct. 20 in R-band  and Oct. 21 in integral light.\n\nAfter refined  analysis of  Oct. 20 observation (Rumyantsev et al., GCN\n5740) two objects were identified within/near XRT error circle (Guidorzi et\nal., GCN 5733): the object 'a' mentioned in GCN5740, and  the object 'b'.\n(Finding chart is available in\nhttp://grb.rssi.ru/GRB061019/GRB061019R_ZTSh.gif).\nWhile the object 'a' is present in both epochs, the object 'b' marginally\ndetected in the first epoch is absent on the combined image of second epoch\n(the Oct.21 observation).\n\nAstrometry of source 'b' is following:\nRA(J2000)=06 06 30.93 Dec(J2000)=+29 34 12.5 with uncertainties in both\ncoordinate 0.5\". The position of source 'b' coincides within 2-sigma error\nbars with the optical afterglow (Covino et al., GCN 5730). We suggest that\nthe source 'b' is connected with the afterglow. The formal photometry of the\nsource 'b' based on USNO A2.0 (R) stars:\n\nDate (UT),           Filter, R_mag,            R_Lim (3sigma)\nOct.20 00:07 - 01:47 R       24.86 +0.76/-0.44 24.4\nOct.21 00:48 - 01:28 None    -                 24.5\n\nThis message may be cited.",
