(IKI) report on behalf of larger GRB follow-up collaboration:
We observed the field of 161129A (Kocevski et al., GCN 20210) with
Zeiss-1000 (East) 1-m telescope of Tien Shan Astronomical Observatory.
We obtained several images in R filter starting on 2016-11-29 (UT)
12:51:12. Within enhanced XRT position (Beardmore et al. GCN 20211) we
detected optical source which is absent in USNO-B1.0 but barely visible
in DSS2 (red). At the moment we can not say anything about the source
variability. The source might be a superposition of the afterglow and a
host galaxy. Preliminary photometry of the source is following
