GCN 31347) with the 2.4-meter optical\n\ntelescope at Gao-Mei-Gu (GMG) station of Yunnan Observatories. The observation began at\n\nUT 12:31:35, 1, Jan. 2022, about 7.3 hours after the trigger. We clearly detected the afterglow.\n\nThe preliminary magnitude was measured to be R~19.0. The weather turned to be cloudy, and it\n\nprevented us from further observations.\n\n\n\n\nWe appreciate all the astronomers working during the holidays. Happy new year!",
