Cline\non behalf of the Konus-Wind team, report:\n\nThe long-duration GRB 180806A\n(Fermi GBM detection: Malacaria et al., GCN 23095)\ntriggered Konus-Wind at T0=81544.19 s UT (22:39:04.190).\n\nThe burst light curve shows a single pulse with a total duration of ~20 s.\nThe emission is seen up to ~1.2 MeV.\n\nAs observed by Konus-Wind, the burst\nhad a fluence of 2.92(-0.36,+0.41)x10^-5 erg/cm2,\nand a 64-ms peak energy flux, measured from T0+5.712 s,\nof 5.52(-1.59,+1.66)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+7.424 s)\nis best fit in the 20 keV - 16 MeV range\nby the GRB (Band) model with the following parameters:\nthe low-energy photon index alpha = -0.76(-0.14,+0.16),\nthe high energy photon index beta = -2.56(-0.79,+0.32),\nthe peak energy Ep = 352(-53,+59) keV,\nchi2 = 90/94 dof.\n\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB180806_T81544/\n\nAll the quoted errors are at the 90% confidence level.\nAll the quoted values are preliminary.",
