Cline\non behalf of the Konus-Wind team, report:\n\nThe long-duration, soft spectrum GRB 140529A (Cummings, GCN 16340)\ntriggered Konus-Wind at T0=34086.312 s UT (09:28:06.312).\nThe burst light curve shows a single peak with a total duration of ~3 s.\nThe emission is seen up to ~1 MeV.\n\nAs observed by Konus-Wind, the burst had a fluence of \n2.6(-0.3,+0.3)x10^-6 erg/cm2,\nand a 64-ms peak flux, measured from T0+0.248 s, of 1.7(-0.4,+0.4)x10^-6 \nerg/cm2/s\n(both in the 20 keV - 10 MeV energy range).\n\nThe time-averaged spectrum of the burst (measured from T0 to T0+8.448 s)\nis best fit in the 20 keV - 1 MeV range\nby a power law with exponential cutoff model:\ndN/dE ~ (E^alpha)*exp(-E*(2+alpha)/Ep)\nwith  alpha = -1.50(-0.45,+0.54),\nand Ep = 52(-31,+17) keV, chi2 = 66/50 dof.\nFitting by a GRB (Band) model yields the same alpha and Ep,\nand an upper limit on the high energy photon index: beta < -2.92 (chi2 = \n66/49 dof).\n\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB140529_T34086/\n\nAll the quoted errors are at the 90% confidence level.\nAll the quoted values are preliminary.",
