Bai (YNAO) report:\n\n\n\n\nWe observed the field of GRB201103B/ZTF20acozryr/AT2020yxz with\n\nthe 2.4-meter optical telescope at Gao-Mei-Gu (GMG) station of Yunnan\n\nObservatories once again. The observation began at UT 14:27:51, 7th,\n\nNov. 2020. We clearly detected the source, and the preliminary magnitude\n\nis measured to be R~20.9. It seems that the source is fading very slightly.\n\nWe suggest to perform both photometric monitors to obtain the variability\n\nbehavior and spectral observations to obtain the possible spectral evolution\n\nin the following nights.",
