We observed the Swift GRB 160131A (Page et al., GCN 18951) with
Zeiss-1000 (East) 1-m telescope of Tien Shan Astronomical Observatory
starting on Feb. 05 (UT) 14:22:45. We obtained several images in R
filter. We clearly detect optical afterglow (Page et al., GCN 18951;
Yurkov et al., GCN 18952; Guidorzi et al., GCN 18953; Xin et al., GCN
18954; Xin et al., GCN 18955; Watson et al., GCN 18956) in a combined
image. Preliminary photometry is following
