Cline\non behalf of the Konus-Wind team, report:\n\nThe long-duration GRB 161020B\n(IPN triangulation: Hurley et al., GCN Circ. 20091)\ntriggered Konus-Wind at T0=65597.4 s UT (18:13:17.400).\n\nThe burst light curve shows a multipeaked structure\nstarted at ~T0-9 s with a total duration of ~45.6 s.\nThe emission is seen up to 3 MeV.\n\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB161020_T65597/\n\nAs observed by Konus-Wind, the burst\nhad a fluence of 5.12(-0.48,+0.54)x10^-5 erg/cm2,\nand a 64-ms peak flux, measured from T0+3.136 s,\nof 6.42(-1.29,+1.33)x10^-6 erg/cm2/s\n(both in the 20 keV - 10 MeV energy range).\n\nThe time-averaged spectrum of the burst\n(measured from T0 to T0+37.888 s)\nis best fit in the 20 keV - 3 MeV range\nby the GRB (Band) model with the following parameters:\nthe low-energy photon index alpha = -1.03(-0.10,+0.11),\nthe high energy photon index beta = -2.63(-0.59,+0.26),\nthe peak energy Ep = 186(-19,+21) keV\n(chi2 = 69/64 dof)\n\nThe spectrum near the maximum count rate\n(measured from T0+0.256 to T0+5.120 s)\nis best fit in the 20 keV - 3 MeV range\nby the GRB (Band) model with the following parameters:\nthe low-energy photon index alpha = -0.51(-0.10,+0.11),\nthe high energy photon index beta = -2.72(-0.32,+0.21),\nthe peak energy Ep = 224(-16,+17) keV\n(chi2 = 58/61 dof)\n\nAll the quoted errors are at the 90% confidence level.\nAll the quoted values are preliminary.",
