GCN Circular 7471
Y. Urata, K.Y. Huang, C.Y. Shih, T.W. Chen, M. Im, I. Lee, on behalf of EAFON report: "We have monitored the GRB 080319B optical afterglow using Lulin 1-m telescope with B, V, R, I and z' bands from 16:18 to 21:19 (UT). Comparing with former observations made by the LOAO (Urata et al. GCN 7435), the R and I band light curves show an apparent temporal break again at ~0.2 days after the burst. The decay index of the post-break is ~-0.8." This message may be cited.
