Cline\non behalf of the Konus-Wind team, report:\n\nThe short-duration GRB 260127B\n(Fermi-GBM detection: The Fermi GBM team, GCN 43533;\nTrigg, GCN 43573;\nIPN triangulation: Ridnaia et al., GCN 43559;\nAstroSat-CZTI detection: ,GCN 43576;\nGECAM-B observation: Ren et al., GCN 43597;\nInsight-HXMT/HE detection: Ren et al., GCN 43598)\ntriggered Konus-Wind at T0=72154.163 s UT (20:02:34.163).\n\nThe burst light curve shows a multipeaked structure,\nwhich starts at ~T0-0.1 s and has a total duration of ~0.3 s.\n\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB260127_T72154/\n\nAs observed by Konus-Wind, the burst\nhad a fluence of 2.09(-0.27,+0.38)x10^-6 erg/cm2,\nand a 16-ms peak flux, measured from T0+0.062 s,\nof 1.80(-0.40,+0.51)x10^-5 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+0.128 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 = -0.21(-0.27,+0.31)\nand Ep = 796(-151,+261) keV (chi2 = 24/25 dof).\n\nAll the quoted errors are at the 68% confidence level.\nAll the quoted values are preliminary.",
