Kirbiyik (TUG)\nreport on behalf of a larger collaboration\n\n\nWe observed the field of Swift GRB 150910A (Pagani et al., GCN#18264) with\nthe 1.0 meter T100 telescope (Bakirlitepe, TUBITAK National Observatory,\nTurkey), starting September, 10, 20:08:16 UT (~ 11 hours after the\ntrigger). Observations were carried out in the R filter. The afterglow is\ndetected in the R band images with an exposure time of 300 s.\n\n\nUsing USNO-B1 star USNO-B1 1234-0008068 (R.A.=5.65, Dec=+33.45) in the\nfield, the magnitudes of the OT were estimated as follows;\n\n\nt-t0 (hr) exp.(s) filt mag err (+/-)\n\n10.97 300 R 20.09 0.23\n\n11.06 300 R 20.18 0.25\n\n\nAnalysis of further observations with the same filter is ongoing.\n\n\nWe thank to TUBITAK National Observatory for a partial support in using\nT100 telescope with project number 10CT100-95 and technical support.",
