Y.-D. Hu, E. Fernandez-Garcia, A. J. Castro-Tirado (IAA-CSIC), C. Perez 
del Pulgar, A. Castellon, I. Carrasco (Univ. de Malaga),  S. Guziy 
(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.
