follow-up collaboration:
We observed the field of the Swift GRB 160203A (D'Avanzo et al., GCN
18979) with Zeiss-1000 (West) 1-m telescope of Tien Shan Astronomical
Observatory starting on Feb. 03 (UT) 20:31:45. We obtained several
images in R filter. We marginally (S/N ~ 2) detect afterglow (Kruehler
et al., GCN 18980) in a combined image. Preliminary photometry of the
afterglow is following
