Cline on behalf\nof the Konus-Wind team, report:\n\nThe long-duration very bright GRB 131014A\n(Fermi GBM detection: Fitzpatrick & Xiong, GCN 15332;\nFermi LAT detection: Desiante et al., GCN 15333)\ntriggered Konus-Wind at T0=18541.405 s UT (05:09:01.405).\n\nThe light curve shows multiple bright, overlapped\npulses from ~T0 s to ~T0+6~s.\nThe emission at this phase of the event is seen up to ~12 MeV.\nThe burst was followed by a ~150s-long decaying tail of\na weak, soft, extended emission.\n\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB131014_T18541/\n\nAs observed by Konus-Wind, the burst\nhad a fluence of (2.05 � 0.03)x10-4 erg/cm2,\nand a 64-ms peak flux, measured from T0+1.664 s,\nof (2.10 � 0.04)x10-4 erg/cm2/s\n(both in the 20 keV - 10 MeV energy range).\n\nThe time-averaged spectrum (measured from T0 to T0+12.288 s)\nis best fit in the 50 keV - 15 MeV range\nby the GRB (Band) function with the following model parameters:\nthe low-energy photon index alpha = -0.79 � 0.04,\nthe high energy photon index beta = -2.89 � 0.08,\nthe peak energy Ep = 346 � 9 keV,\nchi2 = 118/94 dof.\n\nThe spectrum near the maximum count rate\n(measured from T0+1.536 s to T0+1.792 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 = -0.42 � 0.07,\nthe high energy photon index beta = -2.87 � 0.13,\nthe peak energy Ep = 607 � 25 keV,\nchi2 = 77.5/77 dof.\n\nAll the quoted results are preliminary.",
