Cline\non behalf of the Konus-Wind team, report:\n\nThe long-duration GRB 190701B (IBAS detection: Gotz et al., GCN 24936)\ntriggered Konus-Wind at T0=36303.292 s UT (10:05:03.292).\n\nThe burst light curve shows a multi-peaked structure\nwhich starts at ~T0-3.3 s and has a total duration of ~13 s.\nThe emission is seen up to ~1.3 MeV.\n\nAs observed by Konus-Wind, the burst\nhad a fluence of 3.51(-0.46,+0.70)x10^-6 erg/cm2,\nand a 64-ms peak energy flux, measured from T0-0.072 s,\nof 1.39(-0.63,+0.68)x10^-6 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+16.640 s)\nis best fit in the 20 keV - 1.3 MeV range\nby a power law with exponential cutoff model:\ndN/dE ~ (E^alpha)*exp(-E*(2+alpha)/Ep)\nwith�� alpha = -1.43(-0.33,+0.41),\nand Ep = 112(-30,+64) keV (chi2 = 48/60 dof).\nFitting by the GRB (Band) model yields the same alpha and Ep,\nand an upper limit on the high energy photon index:\nbeta < -2.17 (chi2 = 48/59 dof).\n\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB190701_T36303/\n\nAll the quoted errors are at the 90% confidence level.\nAll the quoted values are preliminary.",
