Bai, C. Wang, Y. Xin (Yunnan Nacional Astronomical Observatory) on
behalf of a larger collaboration, report:
"Following the detection of GRB 190123A by Swift (D'Ai et al. GCNC
23769), the 0.6m BOOTES-4/MET robotic telescope at Lijiang Astronomical
Observatory (China) gathered images starting at 12:36 UT (~0.29 hr after
trigger). No optical afterglow is found down to 20.9 mag (unfiltered
images) within the Swift/XRT error box, consistent with the
non-detections by Swift/UVOT (D'Ai et al. GCNC 23769) or MASTER (Lipunov
et al. GCNC 23770). Observations are ongoing."
