Cline,\non behalf of the Konus-Wind team, report:\n\nThe short-duration GRB 220211A\n(Fermi-GBM detection: The Fermi GBM team, GCN Circ. 31570;\nVeres and Meegan GCN Circ. 31591;\nSwift/BAT-GUANO detection: Tohuvavohu et al., GCN Circ. 31582;\nIPN triangulation: Ridnaia et al., GCN Circ. 31584)\ntriggered Konus-Wind (KW) at T0=4070.727 s UT (01:07:50.727).\n\nThe burst light curve shows a single pulse with\nthe total duration of ~54 ms (20-1500 keV).\n\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB220211_T04070/\n\nAs observed by Konus-Wind, the burst had\na fluence of 3.86(-0.53,+0.82)x10^-7 erg/cm^2 and\na 16-ms peak energy flux, measured from T0-0.040 s,\nof 9.6(-2.1,+2.6)x10^-6 erg/cm^2/s\n(both in the 20 keV - 10 MeV energy range).\n\nSince the main fraction of the burst emission was detected\nbefore the trigger, the spectral analysis was performed using\nthe KW 3-channel light curve data.\n\nModelling the time-integrated spectrum of the burst\n(measured from T0-0.050 s to T0+0.004 s)\nby a power law with exponential cutoff model:\ndN/dE ~ (E^alpha)*exp(-E*(2+alpha)/Ep),\nyields alpha = 0.77(-0.62,+1.32) and Ep = 413(-74,+88) keV.\n\nAll the quoted errors are estimated at the 68% confidence level.\nAll the presented results are preliminary.",
