GCN Circular 15511
D. Xu (DARK/NBI), G.-J. Feng, X. Zhang, A. Esamdin, L. Ma (XAO) report: We observed the IBIS/ISGRI field of GRB 131122A (Gotz et al., GCN 15510) using the 1m telescope located on Mt. Nanshan, Xinjiang, China. We obtained 6x360s R-band frames at a mean time of 22:28:18 UT on 2013-11-22, i.e., 1.055 hr after the INTEGRAL trigger. Visual inspect of the Intergral 1.6 arcmin error circle against DSS II and SDSS shows that no new optical source is detected down to a limiting magnitude of R=20.6 mag.
