Kaplan (Akdeniz Univ.) report\non behalf of a larger collaboration\n\n    We observed the field of Swift GRB 131128A (Sonbas et al., GCN#15533)\nwith the 1.0 meter T100 telescope (Bakirlitepe, TUBITAK National\nObservatory, Turkey), starting November, 28, 17:16:02 UT (~ 2.2 hours after\nthe trigger). 300 s $\\times$ 5  exposures were obtained in the R filter\nunder moderate weather conditions.\n\nWe do not detect an optical  afterglow within the reported XRT error circle\ndown to  a limiting magnitude of 21.2 in the  R band. Our image is\ncalibrated  using USNO B1.0  star USNO-B1 1213-0590145 at  RA :355.25992,\nDEC : +31.301542 (J2000).\n\nWe are grateful to TUBITAK National Observatory for prompt scheduling the\nobservations and technical support.",
