report:
"Following the detection of GRB 190114B by Swift/BAT (Siegel et al. GCNC
23686), the 0.6m BOOTES-4/MET robotic telescope at Lijiang Astronomical
Observatory (China) obtained follow-up�� observations starting at
19:53:24 UT (~0.37 hr after trigger). Within the enhaced Swift/XRT
position (Goad et al. GCNC 23691) an optical source with a preliminary
magnitude of 20.3 mag (clear filter) is detected, fading in brightness
in the late-time images, which we suggest as the optical afterglow to
GRB 190114B at coordinates (J2000) RA = 11:39:29.81, Dec =+18:53:28.1
(+/- 1"). Observations are ongoing."
