Observations started at 02:35:09 \nUT on 2016-02-03 (i.e., 1319 s after the BAT trigger) and 10x150s R-band \nframes were obtained.\n\nWe detect an uncatalogued and decaying source at the position reported \nby Kruehler et al. (GCN 18980), which has m(R)= 18.04 in the first 150s \nexposure, calibrated with the nearby USNN star, #0651-0249724 \n(R1=R2=16.84 mag). The fading nature confirms the source is the \nafterglow of GRB 160203A.",
