Cline on behalf\nof the Konus-Wind team, report:\n\nThe long GRB 120119A (Swift-BAT trigger #512035:\nBeardmore et al., GCN 12859)\ntriggered Konus-Wind at T0=14674.872s UT (04:01:34.872)\n\nThe burst light curve shows a multi-peaked pulse\nwith a total duration of ~61 s.\nThe emission is seen up to ~7 MeV.\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB120119_T14674/\n\nAs observed by Konus-Wind the burst\nhad a fluence of (4.7 � 0.6)x10-5 erg/cm2,\nand a 256-ms peak flux, measured from T0+16.384 s,\nof (3.9 � 0.5)x10-6 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+49.152 s)\nis best fitted in the 20 keV - 10 MeV range\nwith the GRB (Band) model, for which:\nthe low-energy photon index alpha = -0.85 (-0.16, +0.20),\nthe high energy photon index beta = -2.34 (-0.22, +0.15),\nthe peak energy Ep = 153(-19, +21) keV,\nchi2 = 73.5/84 dof.\n\nThe spectrum of the initial pulse\n(measured from T0 to T0+16.384 s) is best fitted\nis best fitted in the 20 keV - 10 MeV range\nwith the GRB (Band) model, for which:\nthe low-energy photon index alpha = -0.92 (-0.13, +0.14),\nthe high energy photon index beta = -2.41 (-0.35, +0.16),\nthe peak energy Ep = 192(-21, +29) keV,\nchi2 = 72.4/84 dof.\n\nAssuming the redshift z=1.73 (Cucchiara & Prochaska, GCN 12865;\nPancoast et al., GCN 12866; Milisavljevic et al., GCN 12867)\nand a standard cosmology model\nwith H_0 = 71 km/s/Mpc, Omega_M = 0.27, Omega_Lambda = 0.73,\nthe isotropic energy release E_iso is (3.6 � 0.5)x10^53 erg,\nthe isotropic peak luminosity L_iso_max is (5.1 � 0.7)x10^52 erg/s,\nand Ep_rest is (265 � 35) keV.\n\nAll the quoted results are preliminary.\nAll the quoted errors are at the 90% confidence level.",
