GCN Circular 12314
X. H. Zhao (YNAO), D. Xu (WIS), J. M. Bai (YNAO), report on behalf of a larger collaboration: We observed the XRT field (Zhang & Grupe, GCN 12308) of GRB 110825A (Hurley et al., GCN 12307) with the 2.4m Gao-Mei-Gu (GMG) telescope equipped with YFOSC in Yunan, China. Observations started at 19:02:36 UT on 27th August 2011 and 3x1200s R-band images were obtained. The possible optical afterglow candidate, derived from a weak detection from a single frame (Xu et al., GCN 12311) is not detected in our stacked R-band image, which gives rise to a 3sigma upper limit of R~23.9 mag for the XRT error circle, calibrated with the same USNO reference star in GCN 12311. No further observation with the GMG telescope is planned.
