Sunyaev (IKI)\n\nreport:\n\nWe observed the error box of GRB 050906 (Parsons et al., GCN 3935) with\nRussian-Turkish 1.5-m telescope (RTT150, Bakirlitepe, TUBITAK National\nObservatory, Turkey). We made 6x300s exposures in R and similar set of\nexposures in I between 00:07--01:16 UT on Sep. 07, and also a set of 300s\nexposures in R band between 00:46-01:35 UT on Sep 08.\n\nComparing our two epochs we found no new or fading source brighter than\nR~22.9. The limiting magnitude in I is 20.5.\n\nWe specially checked that between our two epochs there were no new or\nvariable sources superimposed on the bright nearby galaxy IC 328 (Levan\n& Tanvir GCN 3927).\n\nThis message may be cited.",
