Cline\non behalf of the Konus-Wind team, report:\n\nThe long-duration, very intense GRB 160910A\n(Fermi GBM observation: Veres & Meegan, GCN 19901;\nFermi-LAT detection:  Racusin & Kocevski, GCN 19902;\nCALET Gamma-Ray Burst Monitor detection: Kawakubo et al., GCN 19909)\ntriggered Konus-Wind at T0=62379.089 s UT (17:19:39.089).\n\nThe burst light curve starts with an initial weaker emission followed by\na main bright peak with a duration of ~50 s.\nThe main pulse is followed by a long weak tail seen up to ~T0+150 s.\nThe emission is seen up to ~10 MeV.\n\nAs observed by Konus-Wind, the burst\nhad a fluence of 1.36(-0.09,+0.10)x10^-4 erg/cm2,\nand a 64-ms peak energy flux, measured from T0+5.120 s,\nof 3.51(-0.32,+0.32)x10^-5 erg/cm2/s\n(both in the 20 keV - 10 MeV energy range).\n\nThe time-integrated spectrum of the burst\n(measured from T0 to T0+47.872 s)\nis best fit in the 20 keV - 15 MeV range\nby the GRB (Band) model with the following parameters:\nthe low-energy photon index alpha = -0.81(-0.06,+0.07),\nthe high energy photon index beta = -2.16(-0.12,+0.09),\nthe peak energy Ep = 315(-29,+31) keV,\nchi2 = 97/98 dof.\n\nThe spectrum near the peak count rate\n(measured from T0+4.864 to T0+6.400 s)\nis best fit in the 20 keV - 15 MeV range\nby the GRB (Band) model with the following parameters:\nthe low-energy photon index alpha = -0.15(-0.10,+0.10),\nthe high energy photon index beta = -2.27(-0.09,+0.07),\nthe peak energy Ep = 266(-19,+21) keV,\nchi2 = 100/69 dof.\n\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB160910_T62379/\n\nAll the quoted errors are at the 90% confidence level.\nAll the quoted values are preliminary.",
