Cline on behalf\nof the Konus-Wind team, report:\n\nThe long intense GRB 110815A\n(localized by IPN: Hurley et al., GCN 12277)\ntriggered Konus-Wind at T0=34855.971s UT (09:40:55.971)\n\nThe burst light curve shows two peaks separated by ~13 s.\nThe total duration of the burst is ~20s.\nThe emission is seen up to ~8 MeV.\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB110815_T34855/\n\nAs observed by Konus-Wind the burst\nhad a fluence of (5.0 � 0.5)x10-5 erg/cm2,\nand a 64-ms peak flux, measured from T0+1.920 s,\nof (1.8 � 0.1)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+19.200 s) is best fitted\nin the 20 keV - 10 MeV range by the GRB (Band)\nmodel, for which:\nthe low-energy photon index alpha = -0.85 (-0.1, +0.1),\nthe high energy photon index beta = -2.5 (-0.3, +0.2),\nthe peak energy Ep = 251(-25, +25) keV,\nchi2 = 73/87 dof.\n\nThe spectrum at the maximum count rate\n(measured from T0 to T0+2.816 s) is best fitted\nin the 20 keV - 10 MeV range by the GRB (Band)\nmodel, for which:\nthe low-energy photon index alpha = -0.12 (-0.13, +0.14),\nthe high energy photon index beta = -2.8 (-0.3, +0.2),\nthe peak energy Ep = 300(-20, +22) keV,\nchi2 = 99/87 dof.\n\nAll the quoted results are preliminary.\nAll the quoted errors are at the 90% confidence level.",
