Filippenko (UC Berkeley) report on\n\nbehalf of the KAIT GRB team:\n\n\nWe continued observing the optical afterglow of GRB 210610B\n\n(e.g. Page et al., GCN 30170; Zheng & Filippenko, GCN 30204) with\n\nthe 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at\n\nLick Observatory. A total of 30x60s images were obtained in the\n\nclear (roughly R) filter. The optical afterglow was detected in the\n\ncoadd image with a mag of 20.0 +/- 0.2 at ~1.44 days after burst,\n\ncalibrated to the Pan-STARRS1 catalog.",
