TITLE: GCN CIRCULAR NUMBER: 7368 SUBJECT: GRB 080307: BOAO imaging - retraction and new limit DATE: 08/03/07 14:56:48 GMT FROM: Myungshin Im at Seoul Nat U M. Im, I. Lee, W.K. Zheng, K.Y. Huang, Y. Urata on behalf of EAFON team. Earlier, we reported the detection of the after glow of GRB080307 (GCN Circular, #7364). Our reported afterglow at the UVOT position turned out to be a known star, and we retract our earlier report. We do not detect the GRB afterglow at the enhanced XRT position (GCN Circular #7366), and we place the limit of R > 21.2 at 3 sigma. Further analysis is ongoing. This message may be cited.
