(Univ. of Nikolaev) and D. Xiong, Y. Fan, X. Zhao, J. Bai, C. Wang, Y. 
Xin (Yunnan Nacional Astronomical Observatory) on behalf of a larger 
collaboration, report:

Following the detection of GRB 191122A by Swift (Sbarufatti et al. GCNC 
26269), the 0.6m BOOTES-4/MET robotic telescope at Lijiang Astronomical 
Observatory (China) started to gather images at 13:34 UT (~94s after 
trigger). No optical afterglow is found down to 20.3 mag (unfiltered 
images) at the enhaced Swift/XRT position (Evans et al. GCNC 26270), 
consistent with the non-detections by Swift/UVOT (Sbarufatti et al. GCNC 
26269) and CHES (Sun et al. GCNC 26271). Observations are ongoing."

We thank the staff at Lijiang Astronomical Observatory for their 
excellent support.
