Cline\non behalf of the Konus-Wind team, report:\n\nThe long-duration, hard-spectrum GRB 160905A (Swift-BAT trigger #711084:\nD'Avanzo et al., GCN 19887; Barthelmy et al., GCN 19896;\nFermi GBM observation: Bissaldi, GCN 19889;\nFermi-LAT detection: McEnery et al., GCN 19890)\ntriggered Konus-Wind at T0=40735.196 s UT (11:18:55.196).\n\nThe burst light curve shows a double-peaked structure with a total \nduration of ~44 s.\nThe emission is seen up to ~10 MeV.\n\nAs observed by Konus-Wind, the burst\nhad a fluence of 1.50(-0.11,+0.11)x10^-4 erg/cm2,\nand a 64-ms peak energy flux, measured from T0+10.224 s,\nof 1.17(-0.23,+0.23)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+42.240 s)\nis best fit in the 20 keV - 18 MeV range\nby the GRB (Band) model with the following parameters:\nthe low-energy photon index alpha = -0.70(-0.05,+0.06),\nthe high energy photon index beta = -2.39(-0.26,+0.16),\nthe peak energy Ep = 594(-50,+56) keV,\nchi2 = 124/97 dof.\n\nThe spectrum near the peak count rate\n(measured from T0+7.424 to T0+12.288 s)\nis best fit in the 20 keV - 18 MeV range\nby the GRB (Band) model with the following parameters:\nthe low-energy photon index alpha = -0.65(-0.08,+0.09),\nthe high energy photon index beta = -2.53(-0.44,+0.25),\nthe peak energy Ep = 664(-81,+88) keV,\nchi2 = 96/83 dof.\n\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB160905_T40735/\n\nAll the quoted errors are at the 90% confidence level.\nAll the quoted values are preliminary.",
