D. Xu (NAOC/CAS) reports on behalf of a large collaboration:
We observed the field of GRB 160203A (D'Avanzo et al., GCN 18979) using
the LCOGT-1m located at Cerro Tololo. Observations started at 02:35:09
UT on 2016-02-03 (i.e., 1319 s after the BAT trigger) and 10x150s R-band
frames were obtained.
We detect an uncatalogued and decaying source at the position reported
by Kruehler et al. (GCN 18980), which has m(R)= 18.04 in the first 150s
exposure, calibrated with the nearby USNN star, #0651-0249724
(R1=R2=16.84 mag). The fading nature confirms the source is the
afterglow of GRB 160203A.
