Kirbiyik (TUG) report on behalf of a larger collaboration\n\n\n We observed the field of Swift GRB 140907A (Krimm et al., GCN#16788) with\nthe 1.0 meter T100 telescope (Bakirlitepe, TUBITAK National Observatory,\nTurkey), starting September, 7, 23:54:47 UT (~ 7.794 hours after the\ntrigger). Observations were carried out in the R filter. The afterglow is\nclearly detected in 300 s in the R band images.\n\n\nUsing USNO-B1 star USNO-B1 1366-0072923 (R.A.=48.155, Dec=+46.614) in the\nfield, the magnitude of the OT was estimated as follows;\n\nt-t0 (hr) exp.(s) filt mag err (+/-)\n\n7.794 300 R 19.65 0.20\n\n\n We are grateful to TUBITAK National Observatory for prompt scheduling the\nobservations and technical support.",
