S.Y. Fu, Z.P. Zhu, X. Liu, D. Xu (NAOC) report:
We observed the field of GRB 201001A (Simpson et al., GCN 28539) using
the Xinglong-2.16m telescope equipped with the BFOSC camera.
Observations were carried out starting at 19:29:17 UT on 2020-10-01
(i.e., about 9.5 hr after the BAT trigger), and 10x180s, 9x360s R-band
frames were obtained.
No optical source is detected in our stacked image at the enhanced XRT
position (Evans et al., GCN 28540), down to a upper limit of R~21.0,
calibrated with the nearby PanSTARRS field.
We acknowledge great support from the Xinglong-2.16m observing staff, in
particular J. Zheng and A.Y. Zhou.
