Han, Dong.Xu on behalf of EAFON report:\n\nWe began to observe GRB 111222A ( Hurley  et al., GCN 12714)\nwith Xinglong TNT telescope at  Dec 24th, 18:23:18.453 (UT), about  2.15d after \nthe burst.  15 R-band images  were obtained. The exposure time is 300 sec \nfor each frame.\n\nThe source reported by Siegel et al. (GCN 12717) \nwas detected in the each R band image. \nThe brightness of this source was estimated \nto be about 17.6 mag and without any significant change \nduring our observations time \nrelatively to the reference object in USNO B1.0 R2 mag.\n\nThe Coordinates of the reference object and its brightness are  \n11:56:39.863   +69:03:55.50  J2000  R2=16.86 mag, respectively.\n\nThe brightness of the reported source ( Siegel et al.  GCN 12717 ) \nwe observed is brighter than the magnitude reported by USNO B1.0 R2mag\nwhich was R2=18.06 mag. \n\nThis message may be cited.\n\nMore observations are encouraged. \n\nThanks for the observation assistant of TNT telescope at Xinglong observatory.",
