Cline,\non behalf of the Konus-Wind team, report:\n\nThe short-duration, hard-spectrum GRB 160111A\n(IPN triangulation:  Golenetskii et al., GCN 18864)\ntriggered Konus-Wind at 26526.639 s UT (07:22:06.639).\n\nThe KW light curve shows a single pulse with a duration of ~0.3 s.\nThe emission is visible up to ~5 MeV.\n\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB160111_T26526/\n\nAs observed by Konus-Wind, the burst had a fluence\nof 2.4(-0.8,+1.0)x10^-6 erg/cm2, and a 16-ms peak flux,\nmeasured from T0, of 9.7(-3.1,+4.1)x10^-6 erg/cm2/s\n(both in the 20 keV - 10 MeV energy range).\n\nThe spectrum of the burst (measured from T0 to T0+0.128 s)\nis best fit in the 20 keV - 10 MeV range\nby the cutoff power law with the following model parameters:\nthe photon index alpha = -0.06(-0.55,+0.84),\nand the peak energy Ep = 682(-222,+367) keV,\nchi2 = 15.6/19 dof.\nFitting this spectrum with the GRB (Band) function yields\nthe following model parameters:\nthe low-energy photon index alpha = -0.13 (-0.11,+0.08),\nthe high energy photon index beta < -2.35 (upper limit),\nthe peak energy Ep = 725 (-267, +321) keV,\nchi2 = 15.7/18 dof.\n\nAll the quoted errors are at the 90% confidence level.\nAll the quoted values are preliminary.",
