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 190211A by Swift/BAT (Marshall et al. 
GCNC 23883), the 0.6m BOOTES-4/MET robotic telescope at Lijiang 
Astronomical Observatory (China) obtained follow-up ��observations 
starting at 17:10 UT (~0.26 hr after trigger). The optical afterglow is 
detected within the Swift/XRT error box with a preliminary magnitude of 
19.1 mag (clear filter), thus confirming the fading in brightness of the 
optical source earlier reported by Xu et al. (GCNC 23884). Observations 
are ongoing."
