Cline on behalf of the Konus-Wind team, report:\n\nThe long-duration GRB 180923A localized by MAXI/GSC (Maruyama et al., GCN\n23257) and observed by CALET (GBM: Penacchioni et al., GCN 23259) was\ndetected by Konus-Wind (KW) in the waiting mode.\n\nThe burst light curve shows two episodes, started at ~T0(MAXI)-19 s\nwith a total duration of ~ 127 s.\n\nAs observed by KW, the burst had a fluence of\n5.42(-0.65,+1.26)x10^-6 erg/cm2 and a 2.944-s peak flux,\nmeasured from ~T0(MAXI)+93.3 s, of 3.47(-0.92,+1.15)x10^-7 erg/cm2/s\n(both in the 20 - 1000 keV energy range).\n\nModeling the KW 3-channel time-integrated spectrum\n(from ~T0(MAXI)-18.6 s to ~T0(MAXI)+108 s)\nby a simple power-law model yields a power law\nindex of -2.2(-0.2,+0.2), chi2=0.2/1 dof.\n\nThe KW light curve of this burst is available at\nhttp://www.ioffe.rssi.ru/LEA/GRBs/GRB180923A\n\nAll the quoted errors are estimated at the 1 sigma confidence level.\nAll the presented results are preliminary.",
