Cline\non behalf of the Konus-Wind team, report:\n\nThe long-duration, very bright GRB 141104A\n(IPN triangulation: Hurley et al., GCN 17026)\ntriggered Konus-Wind at T0=199.517 s UT (00:03:19.517).\n\nThe light curve shows a double-peaked structure with\na total duration of ~25 s.\nThe emission is seen up to ~10 MeV.\n\nAs observed by Konus-Wind, the burst had a fluence\nof 5.9(-0.4,+0.4)x10^-5 erg/cm2, and a 64-ms peak flux,\nmeasured from T0+8.064 s, of 1.6(-0.1,+0.1)x10^-5 erg/cm2/s\n(both in the 20 keV - 10 MeV energy range).\n\nThe time-averaged spectrum (measured from T0 to T0+27.136 s)\nis best fit in the 20 keV - 15 MeV range\nby the GRB (Band) function with the following model parameters:\nthe low-energy photon index alpha = -1.09 (-0.11,+0.13),\nthe high energy photon index beta = -2.57 (-0.25,+0.15),\nthe peak energy Ep = 160 (-13,+16) keV,\nchi2 = 96/96 dof.\n\nThe spectrum near the peak count rate (measured from T0+7.424 to T0+8.960 s)\nis best fit in the 20 keV - 15 MeV range\nby the GRB (Band) function with the following model parameters:\nthe low-energy photon index alpha = -0.86 (-0.09,+0.11),\nthe high energy photon index beta = -3.32 (-0.81,+0.42),\nthe peak energy Ep = 232 (-18,+16) keV,\nchi2 = 98/96 dof.\n\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB141104_T00199/\n\nAll the quoted errors are at the 90% confidence level.\nAll the quoted values are preliminary.",
