(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.
