Cline on behalf\nof the Konus-Wind team, report:\n\nThe bright short-duration hard GRB 130603B\n(Swift-BAT trigger 557310: Melandri, et al., GCN 14735;\nBarthelmy et al., GCN 14741)\ntriggered Konus-Wind at T0=56956.448s UT (15:49:16.448)\n\nThe light curve shows a multi-peaked structure\nfrom ~T0-0.008 s to ~T0+0.082 s.\nThe total duration of the burst is ~0.090 s\n\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB130603_T56956/\n\nAs observed by Konus-Wind, the burst\nhad a fluence of (6.6 � 0.7)x10-6 erg/cm2,\nand a 16-ms peak flux, measured from T0,\nof (1.0 � 0.2)x10-4 erg/cm2/s\n(both in the 20 keV - 10 MeV energy range).\n\nThe spectrum of the burst (measured from T0 to T0+0.128 s)\nis best fit in the 20 keV - 15 MeV range\nby the cutoff power law with the following model parameters:\nthe photon index alpha = -0.73 � 0.15,\nthe peak energy Ep = 660 � 100 keV,\nchi2 = 67/69 dof.\n\nAll the quoted results are preliminary.",
