GCN Circular 15409
D. Xu (DARK/NBI), G.-J. Feng, H.-B. Niu, A. Esamdin, L. Ma (XAO) report: We observed the field of the LAT error circle of GRB 131029A (Racusin et al., GCN 15399) using the 1m telescope located at Mt. Nanshan, Xinjiang, China, equipped with a 1.2x1.2 deg^2 CCD camera. Three R-band frames with exposures of 180s, 240s, and 300s were obtained at a mean time of 13.656 hr after the Fermi/LAT trigger. At the reported three sub-threshold XRT positions (Evans, GCN 15400), no optical transient is detected down to a limiting magnitude of R=19.5 mag, calibrated with nearby SDSS field.
