collaboration report:
The 2-m LCOGT Faulkes Telescope North began observing Swift GRB160131A
(Page et al. GCN 18951) on Jan 31 at 09:37 UT (~77 minutes after the
burst trigger) with griZY filters. We clearly detect the optical
afterglow (Page et al. GCN 18951; Yurkov et al. GCN 18952), with a
magnitude of r=15.29 +- 0.01 at 81 minutes post GRB, as calibrated
against nearby USNOB-1 star RA(J2000)=05:12:41.5 DEC(2000)=-07:03:09.81
with R2=14.28. Observations are going on.
