We observed the field of Swift GRB 160127A (Amaral-Rogers et al., GCN
18938) with ORI-40 telescope of Khureltogot observatory starting on
Jan., 27 (UT) 19:32:48. We marginally detect optical afterglow
(Amaral-Rogers et al., GCN 18938; Klotz et al., GCN 18939; Cucchiara et
al., GCN 18941). Preliminary photometry of the afterglow is following

2016-01-27 21:10:18 0.55333 none 89*60 n/d n/d 21.2
Photometry is based on nearby SDSS stars, R magnitude deduced from
Lupton's transformations.
