Kawai (TokyoTech) report on behalf of the MITSuME collaboration:
We observed the field of GRB 201223A (J.D. Gropp et al., GCN #29158,
J. Wood et al., GCN #29161) with
the optical three color (g', Rc, and Ic) CCD cameras attached to the
MITSuME 50 cm telescope of Akeno Observatory, Yamanashi, Japan.
The observation started at 2020-12-23 17:59:18 UT (52s after Swift BAT
trigger). We detected the point source at the position consistent with
the afterglow detected previously (Lipunov et al. GCN #29157, Gropp et
al., GCN #29158
