report on behalf of a larger GRB follow-up collaboration:
We observed the field of the Swift GRB 160121A (Hagen et al., GCN 18912)
with Zeiss-1000 (East) 1-m telescope of Tien Shan Astronomical Observatory
starting on Jan. 21 (UT) 16:04:44. We obtained several images in R filter.
We detect afterglow (Oates et al., GCN 18917) in a combined image within
center of the enhanced Swift-XRT position (Osborne et al., GCN 18918).
Preliminary photometry of the afterglow is following
