Cline on behalf\nof the Konus-Wind team, report:\n\nThe short-duration hard-spectrum GRB 121011B\n(IPN localization: Golenetskii at al., GCN 13863)\ntriggered Konus-Wind at T0=81140.083s UT (22:32:20.083)\n\nThe light curve shows a single pulse with a duration of ~0.35 s.\nThe emission is seen up to ~7 MeV.\n\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB121011_T81140/\n\nAs observed by Konus-Wind the burst\nhad a fluence of (2.8 � 0.3)x10-6 erg/cm2,\nand a 16-ms peak flux, measured from T0+0.112 s,\nof (2.3 � 0.4)x10-5 erg/cm2/s\n(both in the 20 keV - 10 MeV energy range).\n\nThe spectrum of the burst (measured T0 to T0+0.192 s)\nis best fit in the 20 keV - 10 MeV range\nby the GRB (Band) function with the following model parameters:\nthe low-energy photon index alpha = -0.45 � 0.37,\nthe high energy photon index beta = -1.9 � 0.4,\nthe peak energy Ep = 670 � 340 keV,\nchi2 = 16.3/17 dof.\n\nAll the quoted results are preliminary.",
