Cline\non behalf of the Konus-Wind team, report:\n\nThe long-duration GRB 180210A\n(Fermi-GBM detection: Bissaldi, GCN Circ. 22407;\nFermi-LAT detection: Dirirsa and Bissaldi, GCN Circ. 22407)\ntriggered Konus-Wind at T0=44678.454 s UT (12:24:38.454).\n\nThe burst light curve shows a multipeaked structure\nwhich starts at ~T0-6 s and has a total duration of ~65 s.\nThe emission is seen up to ~5 MeV.\n\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB180210_T44678/\n\nAs observed by Konus-Wind, the burst\nhad a fluence of 4.81(-0.30,+0.36)x10^-5 erg/cm2,\nand a 64-ms peak flux, measured from T0+20.224 s,\nof 5.35(-1.07,+1.10)x10^-6 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+47.360 s)\nis best fit in the 20 keV - 10 MeV range\nby the GRB (Band) model with the following parameters:\nthe low-energy photon index alpha = -0.49(-0.13,+0.15),\nthe high energy photon index beta = -3.12(-0.54,+0.30),\nthe peak energy Ep = 153(-8,+8) keV\n(chi2 = 84/97 dof).\n\nThe spectrum near the maximum count rate\n(measured from T0+16.128 to T0+22.784 s)\nis best fit in the 20 keV - 10 MeV range\nby the GRB (Band) model with the following parameters:\nthe low-energy photon index alpha = -0.08(-0.24,+0.27),\nthe high energy photon index beta = -3.25(-1.02,+0.37),\nthe peak energy Ep = 152(-11,+12) keV\n(chi2 = 106/91 dof).\n\nAll the quoted errors are at the 90% confidence level.\nAll the quoted values are preliminary.",
