Cline,\non behalf of the Konus-Wind team, report:\n\nThe long-duration GRB 260714B\n(Fermi-GBM detection: The Fermi GBM team, GCN 45161;\nFermi-LAT detection: Gupta and  Lalla, GCN 45162;\nAstroSat-CZTI detection: Pathak et al., GCN 45163;\nGECAM-B detection: Ren et al., GCN 45174;\nSVOM-GRM detection: Ren et al., GCN 45176;\nInsight-HXMT-HE detection: Luo et al., GCN 45188) \ntriggered Konus-Wind at T0=66206.858 s UT (18:23:26.858).\n\nThe burst light curve shows a multipeaked structure\nwhich starts at ~T0-0.4 s and has a total duration of ~15.5 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/GRB260714_T66206/\n\nAs observed by Konus-Wind, the burst\nhad the total fluence of 3.09(-0.20,+0.23)x10^-5 erg/cm2,\nand the 64-ms peak flux, measured from T0+2.640 s,\nof 1.39(-0.15,+0.16)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+15.360 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 = -1.07(-0.04,+0.04),\nthe high energy photon index beta = -3.61(-6.39,+0.71),\nthe peak energy Ep = 595(-44,+55) keV\n(chi2 = 122/94 dof).\n\nThe spectrum near the maximum count rate\n(measured from T0+0.256 to T0+7.168 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 = -0.94(-0.05,+0.05),\nthe high energy photon index beta = -2.97(-1.36,+0.38),\nthe peak energy Ep = 605(-51,+56) keV\n(chi2 = 66/79 dof).\n\nAll the quoted errors are at the 68% confidence level.\nAll the quoted values are preliminary.",
