report on behalf of larger GRB follow-up collaboration:We observed the field of GRB 161113A (D'Avanzo, et al., GCN 20172) with the RC510 telescope (0.51-m f/8) of Kuban State University Astrophysical Observatory.
We obtained several unfiltered images starting on Nov. 14 (UT) 02:02:08. Within enhanced XRT position (Evans et al., GCN 20174) we do not detect any source.
Preliminary photometry of the field is following
