Wang report:\n\nThe late Swift/XRT observations of GRB 140108A (1,2) evidences the\nfullfillment of the IGC paradigm (3,4). A preliminary overlapping of\nits X-ray (0.3-10 keV in rest-frame) luminosity with the one of GRB\n090618, namely an IGC prototype (5), gives an estimate of the redshift\nof z=0.6 (+/- 0.1) (see Fig. 1\n<http://www.icranet.org/images/GCN/GRB140108A.pdf>).\n\nAs a consequence, a supernova associated to GRB 140108A is expected to\nemerge after 16 (+/- 3) days after the trigger.\n\nGiven the spectral parameters of the prompt emission by Swift/BAT\n(<http://gcn.gsfc.nasa.gov/notices_s/583338/BA/>), this redshift\nestimation leads to an isotropic energy of E_iso ~ 4x10^52 erg.\n\nContinuous monitoring and complementary observations in all possible\nwavelengths are encouraged.\n\nReferences:\n(1) Racusin et al., GCN 15699\n(2) D'Avanzo et al., GCN 15706\n(3) Rueda & R.
