Cline\non behalf of the Konus-Wind team, report:\n\nThe long-duration GRB191202A (AstroSat CZTI detection: Gaikwad et al., \nGCN 26326;\nFermi GBM observation: Veres & Meegan, GCN 26329;\nFermi-LAT detection: Kocevski et al., GCN 26330)\ntriggered Konus-Wind at T0=74930.521 s UT (20:48:50.521).\n\nThe burst light curve shows a multi-peaked structure\nwhich starts at ~T0-3.9 s and has a total duration of~17.6 s.\nThe emission is seen up to ~1.3 MeV.\n\nAs observed by Konus-Wind, the burst\nhad a fluence of 2.78(-0.68,+0.76)x10^-5 erg/cm2,\nand a 64-ms peak energy flux, measured from T0+7.024 s,\nof 8.80(-2.80,+3.04)x10^-6 erg/cm2/s\n(both in the 20 keV - 10 MeV energy range).\n\nThe time-integrated spectrum of the burst\n(measured from T0 to T0+15.872 s)\nis best fit in the 20 keV - 1.3 MeV range\nby the GRB (Band) model with the following parameters:\nthe low-energy photon index alpha = -1.22(-0.12,+0.22),\nthe high energy photon index beta = -2.17(-1.00,+0.26),\nthe peak energy Ep = 265(-87,+91) keV,\nchi2 = 46/59 dof.\n\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB191202_T74930/\n\nAll the quoted errors are at the 90% confidence level.\nAll the quoted values are preliminary.",
