Mooley (Oxford, NRAO/Caltech) et al. report\n\nThe X-ray flux of GW170817 on December 03-06 (reported by Troja et al. \n2017, GCN 22201; Margutti et al. 2017, GCN 22203, Haggard et al. 2017, \nGCN 22206 based on the Chandra observations) is exactly as predicted \nlast week by Mooley et al. 2017 (http://arxiv.org/abs/1711.11573) based \non radio spectral indices.\n\nThis suggests that the radio and X-ray emission both arise from a mildly \nrelativistic wide-angle outflow, consistent with the cocoon model (see \nalso Gottlieb et al. 2017, Hallinan et al. 2017, Kasliwal et al. 2017). \nA relativistic jet core, if it exists, is either too weak (having a \nsub-dominant contribution to the radio light curve early on) or too \nstrong (such that its electromagnetic signatures will be observed in the \nfuture). See Mooley et al. 2017 for details.",
