We observed the field of GRB 150910A (Pagani et al., GCN 18264) using
the 1m telescope located at Nanshan, Xinjiang, China. We obtained
3x600s R-band frames with some floating clouds in the sky.

The afterglow (Pagani et al., GCN 18264; Zheng & Filippenko, GCN
18265) is detected in each of the frames. Preliminary results are as
