Bai\n(YNAO) report on behalf of a larger collaboration:\n\nWe observed the afterglow of GRB 120326A (Siegel et al., GCN 13105) with\nthe 2.4m Gao-Mei-Gu (GMG) telescope. Observations started at 19:03:32\nUT on 2012-3-26  (i.e., ~17.7 hrs after the burst) . We found the\nfollowing magnitudes:\n\nStart time post-burst (hr)             Exp. (s)       Filter       Magnitude (err)\n          17.7                                   300            R            18.7 (0.1)\n          17.8                                   300            V            18.7 (0.1)\n          17.9                                   300            B            19.4 (0.1)\n          18.0                                   300            R            18.8 (0.1)\n          18.1                                   300            V            18.8 (0.1)\n          18.2                                   300            B            19.5 (0.1)\n\n The magnitudes were calibrated with the NOMAD1 stars. Further\nobservations are planned.\n\nWe thank the GMG staff, especially W.-M. Yi, H. -Y. Gao and D. -Q.\nWang for performing these observations.\n\n\n2012-03-27 \n\n\n\nzhaoxiaohong78",
