Results of SAO RAS\nobservations of OT are presented in the following table.\n_______________________________________________________________________\ndate of July, UT   filter   exp.            magnitude        telescope\n_______________________________________________________________________\n26.833 -- 27.017   Rc       17 x 300 sec.   22.17 +/- 0.12   Zeiss-1000\n26.856 -- 27.022   B        16 x 300 sec.   23.47 +/- 0.17   Zeiss-1000\n29.819 -- 29.861   Rc       15 x 180 sec.   23.34 +/- 0.09   BTA\n_______________________________________________________________________\n\nWe use USNO-B.1 1460-0295684 (R. A. = 19:06:51.53, Dec. =  +56:04:41.2,\nEpoch = 2000.0) with the magnitudes B2 = 20.39, R2 = 18.06\n(Gorosabel et al. GCN Circ. 12206) as the reference star.\n\nAt the BTA image (ftp://ftp.sao.ru/pub/grb/GRB110726A/GRB110726A_BTA.jpeg)\nwe detected one more faint object with R = 25.21 +/- 0.30, located 3.5\"\nNorth-East from the Swift/UVOT position. According to the Gemini-N redshift\nrange 1.036 < z < 2.7 reported by Cucchiara Bloom & Cenko (GCN Circ. 12202)\nthis angle size corresponds to (110 -- 370) +/- 20 kpc.\n\nThe message may be cited.",
