Huang,\non behalf of EAFON team.\n\n   We re-analyzed the I-band images taken with the 1.8m telescope\n  of the Bohyunsan Optical Astronomy Observatory, Korea.\n  The I-band observation started at 76.1 min after the burst (Holland\n  et al. #7362), and continued for 2100 secs.\n  Our reanalysis of the stacked image show the detection of a possible\n  optial transient within the error circle of the XRT position (Goad et al.\n  #7366), and the reported Gemini-N i-band position (Tanvir et al.7369).\n  The brightness of the OT, calibrated against USNO-B1 star at\n  (09:06:31.6,+35:08,06.4), is I ~ 21.9 +- 0.3 mag with the error arising\n  mostly from the uncertainty associated with the subtraction of\n  the fringe pattern.\n  Further deeper imaging is encouraged.\n\n  We thank J. Seo and Yeon-Bom Jeon for their assistance with\n  the BOAO observation.\n  This message may be cited.",
