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 National Astronomical Observatory) on behalf of a larger 
collaboration, report:

Following the detection of GRB 191106A by Swift (Marshall et al. GCNC 
26177), the 0.6m BOOTES-4/MET robotic telescope at Lijiang Astronomical 
Observatory (China) gathered images starting at 14:21 UT (~5.7 min after 
trigger). No optical afterglow is found down to 20.7 mag (unfiltered 
images) within the Swift/XRT error box, consistent with the 
non-detections by Swift/UVOT (Marshall et al. GCNC 26177) and MASTER 
(Lipunov et al. GCNC 26178). Observations are ongoing.

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