Ma (XAO) report:\n\nWe observed the field of GRB 150910A (Pagani et al., GCN 18264) using\nthe 1m telescope located at Nanshan, Xinjiang, China. We obtained\n3x600s R-band frames with some floating clouds in the sky.\n\nThe afterglow (Pagani et al., GCN 18264; Zheng & Filippenko, GCN\n18265) is detected in each of the frames. Preliminary results are as\nfollows\n\nMid Time  Exposure  Mag   MagErr\n(hr)            (s)\n4.91         600          19.40    0.20\n5.14         600          19.55    0.20\n5.31         600          19.30    0.20\n\nand calibrated with the nearby SDSS field.",
