Cline\non behalf of the Konus-Wind team, report:\n\nThe long-duration, very bright GRB 150330A\n(Fermi-GBM detection: Stanbro, GCN 17568\nIPN triangulation: Hurley et al., GCN 17659)\ntriggered Konus-Wind at T0=71538.572 s UT (19:52:18.572).\n\nThe light curve starts with a double-peaked pulse\nlasting from ~T0 to ~T0+10 s followed by a bright\nmulti-peaked structure from ~T0+97 s to ~T0+195 s.\nThe emission is seen up to ~15 MeV.\n\nAs observed by Konus-Wind, the burst had a fluence\nof 2.1(-0.2,+0.2)x10^-4 erg/cm2, and a 64-ms peak flux,\nmeasured from T0+130.560 s, of 3.4(-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+194.560 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 = -0.96 (-0.07,+0.07),\nthe high energy photon index beta = -2.16 (-0.11,+0.08),\nthe peak energy Ep = 222 (-20,+21) keV,\nchi2 = 85/97 dof.\n\nThe spectrum near the peak count rate (measured from T0+129.536\nto T0+131.072 s) is 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 = -0.72 (-0.09,+0.09),\nthe high energy photon index beta = -1.98 (-0.08,+0.06),\nthe peak energy Ep = 341 (-44,+52) keV,\nchi2 = 107/96 dof.\n\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB150330_T71538/\n\nAll the quoted errors are at the 90% confidence level.\nAll the quoted values are preliminary.",
