GCN Circular 14927
D. Xu (DARK/NBI), A. Esamdin, L. Ma, C.-H. Bai, G.-J. Feng (XAO) report: We observed the field of GRB 130625A (Grupe et al., GCN 14923) using the 1m telescope located at Mt. Nanshan, Xinjiang Astronomical Observatory, China. We obtained 6x300s R-band frames with a mean time of 15:40:08 UT on 2013-06-25, (i.e., 8.658 hr after the burst). No optical source is detected within the enhanced XRT error circle (Goad et al., GCN 14924) in the stacked image, down to a limit magnitude of R=21.0 mag, calibrated with the USNO B1 catalog.
