Cline\non behalf of the Konus-Wind team, report:\n\nA long duration GRB 141102A (Swift-BAT detection: Cummings et al., GCN \n17020; Fermi-GBM detection: Zhang, GCN Circ. 17021) triggered Konus-Wind \nat T0=46296.656 s UT (12:51:36.656).\n\nThe KW triggered on the most intense episode with a duration of about \n0.6 s. There is a possible precursor at ~T0-80 s.\n\nThe emission in this episode is seen up to ~1 MeV.\n\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB141102_T46296/\n\nAs observed by Konus-Wind, the episode\nhad a fluence of 1.43(-0.42,+1.28)x10^-6 erg/cm2,\nand a 16-ms peak flux, measured from T0-0.022 s,\nof 5.95(-2.53,+7.28)x10^-6 erg/cm2/s\n(both in the 20 keV - 10 MeV energy range).\n\nThe time-averaged spectrum of the episode\n(measured from T0 to T0+0.256 s)\nis best fit in the 20 keV - 1 MeV range\nby a power law with exponential cutoff model:\ndN/dE ~ (E^alpha)*exp(-E*(2+alpha)/Ep)\nwith  alpha = -0.58 (-0.61,+0.93)\nand Ep = 444 (-192,+1246) keV (chi2 = 21/28 dof).\nFitting by a GRB (Band) model yields the same alpha and Ep,\nand an upper limit on the high energy photon index: beta < -1.3\n(chi2 = 21/27 dof)\n\nAll the quoted errors are at the 90% confidence level.\nAll the quoted values are preliminary.",
