Cline on behalf\nof the Konus-Wind team, report:\n\nThe short-duration hard GRB 120811B\n(IPN localization: Golenetskii at al., GCN 13620)\ntriggered Konus-Wind at T0=01231.575s UT (00:20:31.575)\n\nThe light curve shows a double pulse,\na total duration of the burst is ~0.33 s.\nThe emission is seen up to ~6 MeV.\n\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB120811_T01231/\n\nAs observed by Konus-Wind the burst\nhad a fluence of 4.6(-0.9,+1.0)x10-6 erg/cm2,\nand a 16-ms peak flux, measured from T0,\nof 2.8(-0.6,+0.7)x10-5 erg/cm2/s\n(both in the 20 keV - 10 MeV energy range).\n\nThe spectrum of the burst (measured from T0 to T0+0.256 s)\nis best fit in the 20 keV - 7 MeV range\nby a power law with exponential cutoff model, for which\nalpha = -0.14 (-0.28, +0.35),\nand Ep = 1130(-230, +310) keV,\nchi2 = 13.6/24 dof.\n\nAll the quoted results are preliminary.\nAll the quoted errors are at the 90% confidence level.",
