WeiKang Zheng and Alexei V. Filippenko (UC Berkeley) report on
behalf of the KAIT GRB team:
The 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at
Lick Observatory, responded to the Swift GRB 210207B (Lien et al.,
GCN 29420) starting at ~0.657 days after the trigger.
A total of 20x60s images were obtained in the clear (roughly R) filters.
We marginally detect the optical afterglow (Lien et al., GCN 29420;
Kumar et al., GCN 29421) in the coadd image with a mag of 20.3 +/- 0.3,
calibrated to the Pan-STARRS1 catalog.
