N.\nKomarova (SAO RAS, Niznijh Arkhyz, Russia), report:\n\nWe performed the third epoch of observations of the GRB 100805A (Hoversten\nE. A. et al., GCN 11047) field with the Zeiss-1000 telescope of SAO RAS,\nRussia. The observations were carried out in the Rc band on Aug. 9.882 -\n10.043 UT under good weather conditions and the seeing 1\".7.\n\nAt the position of OT we detected an object with R = 23.54 +/- 0.22.\n\nWe assume the magnitude of the reference USNO-B1.0 star (L. P. Xin et al.,\nGCN 11065; A. S. Moskvitin et al., GCN 11071, A. S. Moskvitin et al.,\nGCN 11076) as R = 17.41.\n\nAlso we estimate the magnitude of the source reported by V. Rumyantsev and\nA. Pozanenko (GCN 11077) as R = 22.31 +/- 0.08 according to their standard\nstar with R=17.59. All errors are formal and they do not include errors of\nthe USNO-B1.0 to Johnson-Cousins photometric system transformation.\n\nImages from all 3 epochs with the marked OT and nearby object (GCN 11077)\ncan be found in\nftp://ftp.sao.ru/pub/grb/GRB100805A/GRB100805A_Zeiss1000.jpeg\n\nThis message may be cited.",
