Mangano (INAF IASF Pa) report on behalf of the SWIFT team\n\nWe have analyzed the afterglow light curve of GRB061126 (GCN 5854, \nSbarufatti et  al.) observed with XRT.\nThe source is decaying as a simple power law with slope alpha=-1.31 +/- \n0.01 since its first detection with XRT up to T+76ks.\nWe do not find evidence of the possible jet break reported by Kann et \nal. (GCN 5875) - but not detected by Rol et al. (GCN 5876) - at 1.8 days \nafter the trigger.\nA  tentative fit with a broken powerlaw, albeit very poorly constrained, \n  showed a marginal compatibility with a flattening of the light curve \nafter T+1E5s, as opposed with the steepening expected from a jet break.\n\nXRT observation of the afterglow (which shows a count rate 1.5E-3 c/s at \nT+76 ks)are still ongoing.\n\nThis circular is an official product of the Swift XRT Team.",
