Cline, \non behalf of the Konus-Wind team, report: \n \nThe long-duration GRB 241114B \n(Insight-HXMT-HE detection: Wang et al., GCN 38284; \nIPN triangulation: Svinkin et al., GCN 38341) \ntriggered Konus-Wind at T0=39903.659 s UT (11:05:03.659). \n \nThe burst light curve shows a multipeaked structure \nwhich starts at ~T0-11.7 s and has a total duration of ~45 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/GRB241114_T39903/ \n \nAs observed by Konus-Wind, the burst \nhad a fluence of 4.03(-0.38,+0.43)x10^-5 erg/cm2, \nand a 64-ms peak flux, measured from T0+23.648 s, \nof 1.38(-0.22,+0.24)x10^-5 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+32.768 s) \nis best fit in the 20 keV - 16 MeV range \nby the GRB (Band) model with the following parameters: \nthe low-energy photon index alpha = -1.15(-0.10,+0.11), \nthe high energy photon index beta = -3.11(-6.89,+0.49), \nthe peak energy Ep = 258(-25,+30) keV \n(chi2 = 123/97 dof). \n \nThe spectrum near the maximum count rate \n(measured from T0+16.640 s to T0+24.576 s) \nis best fit in the 20 keV - 16 MeV range \nby the GRB (Band) model with the following parameters: \nthe low-energy photon index alpha = -0.76(-0.14,+0.17), \nthe high energy photon index beta = -3.08(-6.92,+0.46), \nthe peak energy Ep = 272(-30,+31) keV \n(chi2 = 84/77 dof). \n \nAll the quoted errors are at the 90% confidence level. \nAll the quoted values are preliminary.",
