Cline, on behalf of the Konus-Wind team report:\n\nThe GRB 081001 localized by SuperAGILE\n(Lazzarotto et al., GCN 8305) triggered Konus-Wind\nat T0=76663.649 s UT (21:17:43.649).\n\nThe burst light curve shows a main pulse with a duration of ~6 s \nfollowed by a much weaker pulse at T0+~30 s with a duration of ~10 s.\n\nAs observed by Konus-Wind the burst\nhad a fluence of 9.70(-0.86, +1.00)x10^-6 erg/cm2,\nand a 64-ms peak flux measured from T0+0.688 s\nof 5.63(-1.12, +1.16)x10^-6 erg/cm2/s\n(both in the 20 keV - 2 MeV energy range).\n\nThe spectrum of the main pulse\n(from T0 to T0+8.448 s) is well fitted (in the 20 keV-2 MeV range)\nby a power law with exponential cutoff model:\ndN/dE ~ (E^alpha)*exp(-E*(2+alpha)/Ep)\nwith alpha = -0.99(-0.18, +0.21),\nand Ep = 239(-32, +45) keV (chi2 = 54.9/61 dof).\nFitting by GRBM (Band) model yields:\nthe low-energy photon index is alpha = -0.95(-0.21, +0.48),\nthe high energy photon index beta < -2.14,\nthe peak energy Ep = 227(-70, +52) keV (chi2 = 54.1/60 dof).\nAll the quoted errors are at the 90% confidence level.\n\nThe Konus-Wind light curve of this GRB is available\nat http://www.ioffe.rssi.ru/LEA/GRBs/GRB081001_T76663/",
