Han on behalf of EAFON report:\n\nWe began to observe GRB110112A (stamatikos et al., GCN 11553 ) \nwith Xinglong TNT telescope at 10:08:35.375 (UT), 6 hours after \nthe burst. 16 images in R-band were obtained with an exposure \ntime of 300 sec for each frame. \n\nAfter combining all these images, a new marginal source was \nfound within the errorbox  of X-ray counterpart \n( stamatikos et al., GCN 11553). \n\nIts coordinates ( RA and Dec ) are 21:59:43.8 26:27:25.9 (J2000)\nwith an uncertainty of  about 1 arcsecond.\n\nThe brightness of the source is estimated to be about \n19.6 +/- 0.3 mag which is derived from USNO B1.0 R2 mag \nat the mean time of 6.5 hour after the burst. \n\nFurther observations and confirmation are encouraged.\n\nThis message may be cited.\n\nFor more information about Xinglong GRBs Follow-up\nobservations, please visit the website:\nhttp://www.xinglong-naoc.org/grb/",
