Cline,\non behalf of the Konus-Wind team, report:\n\nThe long GRB 241130A (Fermi-GBM detection:\nThe Fermi GBM team, GCN 38405, Sharma et al., GCN 38421;\nEIRSAT-1 GMOD Detection: McDermott et al., GCN 38423;\nIPN triangulation: Ridnaia et al., GCN 38424)\ntriggered Konus-Wind (KW) at T0=83628.376 s UT (23:13:48.376).\n\nThe burst light curve shows a single, FRED-like pulse,\nwhich starts at ~T0-0.5 s, peaks at ~T0+0.3 s,\nand has a total duration of ~10 s.\nThe emission is seen up to ~2 MeV.\n\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB241130_T83628/\n\nAs observed by Konus-Wind, the burst had\na fluence of (1.52 ± 0.21)x10^-5 erg/cm^2 and\na 64-ms peak energy flux, measured from T0 + 0.384 s,\nof (1.77 ± 0.22)x10^-5 erg/cm^2/s (both in the 20 keV - 10 MeV energy range).\n\nThe time-integrated spectrum (measured from T0 to T0+8.448 s)\nis best fit in the 20 keV - 15 MeV range by a power law with exponential\ncutoff (CPL) model: dN/dE ~ (E^alpha)*exp(-E*(2+alpha)/Ep)\nwith  alpha = -1.25(-0.08,+0.09) and Ep = 663(-128,+185) keV (chi2 = 66/81 dof).\nFitting this spectrum by a Band function yields the same values of alpha and Ep,\nand an upper limit on the high energy photon index beta of -2.4 (chi2 = 66/80 dof).\n\nAll the quoted errors are estimated at the 90% confidence level.\nAll the presented results are preliminary.\n",
