Cline\non behalf of the Konus-Wind team, report:\n\nThe long-duration, intense GRB 140825A\n(IPN triangulation: Hurley et al., GCN 16752)\ntriggered Konus-Wind at T0=24925.66 s UT (06:55:25.660).\n\nThe burst light curve shows several peaks with a total duration of ~14 s.\nThe emission is seen up to ~10 MeV.\n\nAs observed by Konus-Wind, the burst\nhad a fluence of 3.7(-0.2,+0.2)x10^-5 erg/cm2,\nand a 64-ms peak energy flux, measured from T0+1.984 s,\nof 1.4(-0.2,+0.2)x10^-5 erg/cm2/s\n(both in the 20 keV - 10 MeV energy range).\n\nThe time-integrated spectrum of the burst\n(measured from T0 to T0+10.752 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 = -0.94(-0.07,+0.08),\nthe high-energy photon index beta = -3.42(-1.36,+0.40),\nthe peak energy Ep = 142(-7,+7) keV,\nchi2 = 86/84 dof.\n\nThe spectrum near the peak count rate\n(measured from T0+2.048 to T0+2.560 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 = -0.44(-0.15,+0.21),\nthe high-energy photon index beta = -3.42(-1.61,+0.59),\nthe peak energy Ep = 208(-23,+18) keV,\nchi2 = 41/44 dof.\n\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB140825_T24925/\n\nAll the quoted errors are at the 90% confidence level.\nAll the quoted values are preliminary.",
