behalf of a larger collaboration:
We observed the field of GRB 180205A (Evens et al., GCN 22381) using the
1m telescope located at Nanshan, Xinjiang, China, and 10x60s R-band
frames, starting at 16:31:07 UT on 2018-02-05.
The optical afterglow (e.g., Evens et al., GCN 22381; Zheng et al., GCN
22382) is clearly detected in our stacked image.
Preliminary photometry results are as follows:

Photometry is calibrated with nearby SDSS stars, and errors are only
statistical values.
