J. Wang, X. H. Han, X. M. Meng and C. Wu report:
We began to observe GRB 180111A (Lien et a l., GCN22318)
with Xinglong 0.8-m TNT telescope at 2018-01-11, 14:43:34(UT),
about 93 sec the burst.
We obtained several white and R-band images.
In any single white band frame, no any new optical transient
was detected within UVOT circle and XRT circle
(Lien et a l., GCN22318, Evens et al., GCN 22319)
down to 18.5 magnitude at the mid time of 113 sec after the burst .
However, there is a marginal source in the 20*20sec coadded image
within the XRT circle (Evens et al., GCN 22319), whose position is consistent
with the location of the reported optical counterpart (Lien et a l., GCN22318).
The brightness is about 20.0+/-0.3 calibrated by the local USNO B1.0 R2 mag
at the mid time of 300 sec after the burst.
We are making further analysis for the possible low S/N detection
since there is a bright star near the GRB location.
The message may be cited.
[GCN OPS NOTE(11jan18): The latter 'A' was added to the GRB name
in the Subject-line.]
