Han on behalf of EAFON report:\n\nWe began to observe GRB110411A ( Grope et al., GCN 11918) \nwith Xinglong TNT telescope at  19:35:32 (UT), 81 sec after \nthe burst. A series of White and R-band images were obtained. \nWith the combination of all R-band images of 37*60 sec \nexposure time, we detected an new source nearby the \nerrorbox  of X-ray counterpart ( Goad et al., GCN 11920 ).\n\nThe coordinates of new source are:\n\nRa:    19:25:45.65 \nDec:   67:42:39.1\nEpoch: J2000\n\nThe uncertainty of the coordinates is about 1 arc. \n\nThe brightness of this source is estimated to be about \n21 +/- 0.2 mag in the R band, at the mean time of 38 min \nafter the burst, comparing to an USNO B1.0 R2 reference star, \nof which the coordinates are \n19:25:52.432 +67:43:44.07 J2000 R2=16.18mag.\n\nWe proposed that the new source be the optical \ncounterpart of GRB 110411A.\n\nThis message may be cited.",
