GRB follow-up collaboration:
We observed the field of Swift GRB 160131A (Page et al., GCN 18951) with
AS-32 (0.7m) telescope of Abastumani Observatory starting on Jan. 31
(UT) 19:16:57. We obtained several unfiltered images of 120 s exposure.
We 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). Preliminary light curve can be
found in http://grb.rssi.ru/GRB160131A/GRB160131A_20160131_AbAO_lc.png
The photometry is base on nearby USNO-B1.0 stars:
