Ltd., Jiangsu) report:\n\nWe observed the field of GRB 141130A (Vargas et al., GCN  17120) with\nthe 36cm robotic telescope located at Nanshan, Xinjiang, China.\nObservations started at 23:12:44 UT on 2014-10-30, i.e., 108 s after\nthe burst, and subsequently 4x40s, 8x60s, and 10x90s R-band images\nwere obtained under some floating clouds.\n\nThe optical afterglow, at the UVOT position, is clearly detected in\nthe stacked 4x40s image, with R=17.67+/-0.20 mag at a median time of\n201 s post-burst, against the same four SDSS stars in Xu et al. (GCN\n17122). The afterglow is not detected any more in the subsequent\nimages down a limit of R~18 mag. This is consistent with the\nmeasurement of R~18.5 mag at 258 s after post-burst in Mazaeva et al.\n(GCN 17121).",
