Cline on behalf\nof the Konus-Wind team, report:\n\nThe long intense GRB 120602A\n(IPN localization: Hurley at al., GCN 13365)\ntriggered Konus-Wind at T0=18000.228s UT (05:00:00.228)\n\nThe light curve shows a bright pulse at ~T0+55 s,\npreceded by several weaker overlapping pulses.\nA total burst duration of the burst is ~70 s.\nThe emission is seen up to ~9 MeV.\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB120602_T18000/\n\nAs observed by Konus-Wind the burst\nhad a fluence of (3.6 � 0.1)x10-4 erg/cm2,\nand a 64-ms peak flux, measured from T0+54.912 s,\nof (3.9 � 0.5)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+60.416 s)\nis best fitted in the 20 keV - 10 MeV range\nwith the GRB (Band) model, for which:\nthe low-energy photon index alpha = -0.77 (-0.03, +0.03),\nthe high energy photon index beta = -2.8 (-0.1, +0.1),\nthe peak energy Ep = 300(-10, +10) keV,\nchi2 = 104.3/80 dof.\n\nThe spectrum at the maximum count rate\n(measured from T0+54.784s to T0+55.040 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 = -0.85 (-0.10, +0.12),\nthe high energy photon index beta = -2.9 (<-2.5),\nthe peak energy Ep = 530(-90, +90) keV,\nchi2 = 39.2/45 dof.\n\nAll the quoted results are preliminary.\nAll the quoted errors are at the 90% confidence level.",
