J. Mao, B.-L. Lun, and J.-M. Bai (YNAO) report:
We observed the field of GRB 220101A (Tohuvavohu et al. GCN 31347) with the 2.4-meter optical
telescope at Gao-Mei-Gu (GMG) station of Yunnan Observatories. The observation began at
UT 12:31:35, 1, Jan. 2022, about 7.3 hours after the trigger. We clearly detected the afterglow.
The preliminary magnitude was measured to be R~19.0. The weather turned to be cloudy, and it
prevented us from further observations.
We appreciate all the astronomers working during the holidays. Happy new year!
