Romano (INAF-OAB) on behalf of the\nSwift/XRT team:\n\nAfter the analysis of the full initial dataset, we see that the\nlight curve of GRB051109A shows a further break besides the one\nalready highlighted previously (Campana et al., GCN 4228).\nThis second break is relatively unconstrained occurring between\nthe first (<200 s) and the second (>3000 s) Swift orbit.\nIn the first part the decay is very steep with index\nalpha_1=-3.1 +/- 0.6 (90% containment, as reported). The second\npower law contains basically no data and it is only loosely\nconstrained. The third power law has alpha_3=-1.2 +/- 0.1.\nThe reduced chi2 is 1.2 (57 dof).\nThe expected flux at 1 day is 8e-13 erg cm^-2 s^-1.\n\n[GCN_OPS_NOTE(09nov05): Per author's request, the Subject line\nwas changed from \"050911A\" to \"051109A\".]",
