Cline,\non behalf of the Konus-Wind team, report:\n\nThe long GRB 200122A (Swift detection:  Sonbas et al., GCN 26844)\ntriggered Konus-Wind (KW) at T0=6066.859 s UT (01:41:06.859).\n\nThe burst light curve shows a multi-peaked structure\nin the interval from ~T0-12 s to ~T0+26 s.\nThe total duration of the burst is ~40 s.\nThe emission is seen up to ~10 MeV.\n\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB200122_T06066/\n\nAs observed by Konus-Wind, the burst had\na fluence of (2.0 �� 0.3)x10^-5 erg/cm^2 and\na 64-ms peak energy flux, measured from T0+6.080,\nof (5.7 �� 0.7)x10^-6 erg/cm^2/s (both in the 20 keV - 10 MeV energy range).\n\nThe time-integrated spectrum (measured from T0 to T0+24.832 s)\nis best fit in the 20 keV - 20 MeV range\nby the GRB (Band) function with the following model parameters:\nthe low-energy photon index alpha = -1.00 (-0.13,+0.16),\nthe high energy photon index beta = -2.81 (-0.94,+0.32),\nthe peak energy Ep = 148 (-16,+15) keV,\nchi2 = 83/96 dof.\n\nThe spectrum near the peak count rate (measured from T0\nto T0+8.448 s) is best fit in the 20 keV - 15 MeV range\nby the GRB (Band) function with the following model parameters:\nthe low-energy photon index alpha = -0.88 (-0.16,+0.19),\nthe high energy photon index beta = -2.37 (-0.39,+0.16),\nthe peak energy Ep = 168 (-22,+31) keV,\nchi2 = 83/96 dof.\n\nAll the quoted errors are estimated at the 68% confidence level.\nAll the presented results are preliminary.",
