Cline on behalf\nof the Konus-Wind team, report:\n\nThe bright long-duration hard-spectrum 140308A (IPN triangulation: \nHurley et al., GCN 15941) triggered Konus-Wind at T0=13764.906 s UT \n(03:49:24.906).\n\nThe burst light curve shows a multi-peaked structure with a total \nduration of ~90 s. The emission is seen up to ~18 MeV.\n\nAs observed by Konus-Wind, the burst\nhad a fluence of (1.01 +/- 0.10)x10^-4 erg/cm2,\nand a 256-ms peak flux, measured from T0+16.976 s,\nof (8.7 +/- 1.6)x10^-6 erg/cm2/s\n(both in the 20 keV - 10 MeV energy range).\n\nThe time-averaged spectrum (measured from T0 to T0+65.024 s)\nis best fit in the 26 keV - 18 MeV range\nby the GRB (Band) function with the following model parameters:\nthe low-energy photon index alpha = -0.81 (-0.15,+0.17),\nthe high energy photon index beta = -2.07 (-0.16,+0.11),\nthe peak energy Ep = 246 (-35, 45) keV,\nchi2 = 109/97 dof.\n\nThe spectrum near the maximum count rate\n(measured from T0+15.872 to T0+24.064 s)\nis best fit in the 26 keV - 18 MeV range\nby the GRB (Band) function with the following model parameters:\nthe low-energy photon index alpha = -0.67 (-0.26,+0.29),\nthe high energy photon index beta = -2.06 (-0.26,+0.14),\nthe peak energy Ep = 228 (-43, 74) keV,\nchi2 = 96/97 dof.\n\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB140308_T13764/\n\nAll the quoted errors are at the 90% confidence level.\nAll the quoted values are preliminary.",
