TITLE: GCN CIRCULAR NUMBER: 15794 SUBJECT: GRB 140206A: theoretical prediction of redshift and of supernova occurrence DATE: 14/02/06 18:05:40 GMT FROM: Remo Rufinni at ICRA R. Ruffini, C.L. Bianco, M. Enderli, M. Kovacevic, M. Muccino, A.V. Penacchioni, G.B. Pisani, J.A. Rueda, Y. Wang report: The late Swift/XRT observations of GRB 140206A (1,2) evidences the fullfillment of the IGC paradigm (3,4). A preliminary overlapping of its X-ray (0.3-10 keV in rest-frame) luminosity with the one of GRB 090618, namely an IGC prototype (5), gives an estimate of the redshift of z~0.6 (see Fig. 1 ). As a consequence, a supernova associated to GRB 140206A is expected to emerge after 16 days after the trigger. Continuous monitoring and complementary observations in all possible wavelengths are encouraged. References: (1) Lien et al., GCN 15784 (2) Osborne et al., GCN 15793 (3) Rueda & R.
