Cline,\non behalf of the Konus-Wind team, report:\n\nA bright burst from SGR 1935+2154\n(also detected by Fermi-GBM (trigger 692607435)\nand GECAM (both reported in GCN Notices))\ntriggered Konus-Wind at T0=25026.883 s UT (06:57:06.883)\non 2022 December 13.\n\nThe burst light curve shows a bright pulse,\nwhich starts at ~T0-96 ms and has a total duration of ~142 ms.\nThe emission is seen up to ~200 keV.\n\nThe Konus-Wind light curve of this burst is available at\nhttp://www.ioffe.ru/LEA/SGRs/221213_T25026/\n\nAs observed by Konus-Wind, the burst\nhad a fluence of 6.61(-0.48,+0.48)x10^-7 erg/cm2,\nand a 16-ms peak flux, measured from T0-0.012 s,\nof 1.31(-0.16,+0.16)x10^-5 erg/cm2/s\n(both in the 20 - 500 keV energy range).\n\nThe spectrum of the burst\n(measured from T0 to T0+0.064 s)\nis best fit in the 20 - 500 keV range\nby a power law with exponential cutoff model:\ndN/dE ~ (E^alpha)*exp(-E*(2+alpha)/Ep)\nwith  alpha = 0.12(-1.06,+1.30)\nand Ep = 37(-8,+4) keV (chi2 = 15/11 dof).\n\nAll the quoted errors are at the 90% confidence level.\nAll the quoted values are preliminary.",
