Castro-Tirado (IAA-CSIC Granada), on behalf\nof a larger collaboration, report:\n\n\"We observed SGR 1834.9-0846/ GRB 110807A detected by Swift/BAT (D'Elia et\nal., GCNC 12253, Barthelmy, GCN 12259) with the OSN 1.5m telescope. I-band\nframes were obtained on 7 Aug, starting 16 min after the gamma-ray detection\n(i.e. simultaneously to the BTA Rc-band observations, Moskvitin et al., GCNC\n12254). Neither on the single I-band images (10s exposure time each) nor on\nthe co-added frames, taken between 20:14 and 21:48 UT, with total exposure\n4820 sec, an object is detected within the Swift/XRT error box. The limiting\nmagnitude for the combined image is I = 21.6 (calibrated against USNO\nB1.0).\"\n\nThis message may be cited.",
