We  observed  GRB 160131A (Page et al. GCN 18951)  with
60cm WFT telescope at 10:29:14UT,  about 127 min after the burst.
The optical afterglow (Page et a.., GCN 18951, YurKov et al., GCN 18952,
Guidorzi et al., GCN 18953,  Xin et al., 18954) was  detected 
in our white and R-band  images.  The brightness of the optical afterglow 
is about 15.85 mag at the mid time  of 127.5 min afer the burst,  calibrated by 
the USNO B1.0 star (RA=05:12:39.8  DEC=-7:02:02  R2=15.51mag).
