GCN Circular 12718
L.P. Xin, J.Y. Wei, Y. L. Qiu, J. Wang, J.S. Deng, C. Wu, X. H. Han, Dong.Xu on behalf of EAFON report: We began to observe GRB 111222A ( Hurley et al., GCN 12714) with Xinglong TNT telescope at Dec 24th, 18:23:18.453 (UT), about 2.15d after the burst. 15 R-band images were obtained. The exposure time is 300 sec for each frame. The source reported by Siegel et al. (GCN 12717) was detected in the each R band image. The brightness of this source was estimated to be about 17.6 mag and without any significant change during our observations time relatively to the reference object in USNO B1.0 R2 mag. The Coordinates of the reference object and its brightness are 11:56:39.863 +69:03:55.50 J2000 R2=16.86 mag, respectively. The brightness of the reported source ( Siegel et al. GCN 12717 ) we observed is brighter than the magnitude reported by USNO B1.0 R2mag which was R2=18.06 mag. This message may be cited. More observations are encouraged. Thanks for the observation assistant of TNT telescope at Xinglong observatory.
