Cline on behalf of the Konus-Wind team:\n\nThe bright long GRB 070824 localized by SuperAGILE/IPN\n(Donnarumma et al., GCN 6767) triggered Konus-Wind\nat T0=74999.585 s UT (20:49:59.585).\n\nThe Konus-Wind light curve shows two pulses\nwith a total duration of ~12 s.\n\nAs observed by Konus-Wind the burst\nhad a fluence of 2.84(-0.26, +0.09)x10^-5 erg/cm2,\nand a 16-ms peak flux measured from T0+8.368 s\nof 2.85(-0.38, +0.29)x10^-5 erg/cm2/s\n(both in the 20 keV - 2 MeV energy range).\n\nThe time-integrated spectrum of the burst\n(from T0 s to T0+16.986 s) is well fitted\n(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 = 1.051 (-0.081, +0.078)\nand Ep = 253 (-19, +22) keV (chi2 = 66.2/60 dof).\nFitting by a GRBM (Band) model yields:\nthe low-energy photon index alpha = -1.025 +/- 0.084,\nthe high energy photon index beta < -2.55,\nthe peak energy Ep = 243(-20, +24) keV (chi2 = 64.5/59 dof).\n\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/GRB070824_T74999/",
