Huang, Y.\non behalf of EAFON report:\n\nWe have imaged the field of GRB080307 (Holland et al., GCN 7362) \nusing the TNT 0.8 telescope at Xinglong observatory under good\ncondition. A set of White and R band images were obtained.\nPreliminary result shows we margianally detected the afterglow\ncandidate (Tanvir, GCN 7369) in our combined images. By performing\nPSF photometry, we have the following magnitude calibrated to the\nUSNO B1.0 R2 mag:\n\nT_mid(min)  Mag    Band  Exp   Merr\n-------------------------------------\n15.71       20.9   W    10*20s  0.3\n24.50       21.3   R    10*60s  0.3\n70.28       22.1   R    8*300s  0.3\n\nThe source faded during our observation epoch, we confirm this\nis the afterglow of GRB 080307.\n\nThis message may be cited.
