Cline on behalf\nof the Konus-Wind team, report:\n\nThe intense long-duration GRB 130320A\n(IPN triangulation: Hurley et al., GCN 14327)\ntriggered Konus-Wind at T0=25724.822s UT (07:08:44.822)\n\nThe light curve shows a double-peaked pulse with a total\nduration of ~20 s.\nThe emission is seen up to 5 MeV.\n\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB130320_T25724/\nNote: periodic \"dips\" visible in this light curve are due\nto the GRB source occultation by the spacecraft structure.\n\nAs observed by Konus-Wind, the burst\nhad a fluence of (2.6 � 0.05)x10-5 erg/cm2,\nand a 64-ms peak flux, measured from T0+0.960 s,\nof (1.85 � 0.1)x10-5 erg/cm2/s\n(both in the 20 keV - 10 MeV energy range).\n\nThe time-integrated spectrum\n(measured from T0 to T0+22.784 s)\nis best fit in the 20 keV - 10 MeV range\nby a power law with exponential cutoff model,\nfor which:\nalpha = -0.78 � 0.05,\nand Ep = 295 � 7 keV,\nchi2 = 85.0/93 dof.\n\nThe spectrum at the maximum count rate\n(measured from T0 to T0+2.048 s)\nis best fit in the 20 keV - 10 MeV range\nby a power law with exponential cutoff model,\nfor which:\nalpha = +0.27 � 0.06,\nand Ep = 364 � 7 keV,\nchi2 = 91.1/98 dof.\n\nAll the quoted results are preliminary.",
