(IKI) report on behalf of larger GRB follow-up collaboration:
We observed the field of GRB 161011A (D'Elia et al., GCN 20023) with
Zeiss-1000 (East) 1-m telescope of Tien Shan Astronomical Observatory.
We obtained several images in R filter starting on Oct. 11 (UT)
13:13:27. In the enhanced XRT error circle (Osborne al., GCN 20026) we
marginally detect an object which is absent in SDDS-DR9 catalog.
Preliminary photometry of the object which we suggest as an afterglow
candidate is following

(mid, days) (s)
2016-10-11 13:13:27 0.32098 R 21*120 20.6 0.3 20.8
Photometry is based on nearby SDSS-DR9 stars (Lupton transformations):
