on behalf of a larger collaboration

    We observed the field of Swift GRB 131128A (Sonbas et al., GCN#15533)
with the 1.0 meter T100 telescope (Bakirlitepe, TUBITAK National
Observatory, Turkey), starting November, 28, 17:16:02 UT (~ 2.2 hours after
the trigger). 300 s $\times$ 5  exposures were obtained in the R filter
under moderate weather conditions.

We do not detect an optical  afterglow within the reported XRT error circle
down to  a limiting magnitude of 21.2 in the  R band. Our image is
calibrated  using USNO B1.0  star USNO-B1 1213-0590145 at  RA :355.25992,
DEC : +31.301542 (J2000).

We are grateful to TUBITAK National Observatory for prompt scheduling the
observations and technical support.
