Cline\non behalf of the Konus-Wind team, report:\n\nThe long-duration GRB 150527A (Swift-BAT trigger #641698:\nEvans, et al., GCN Circ. 17874; Lien, et al., GCN Circ. 17880;\nFermi-GBM detection: Yu, GCN Circ.17878)\nwas detected by Konus-Wind in the waiting mode.\n\nThe burst light curve shows two emission episodes:\nthe first episode (from ~T0(BAT)-108 s to ~T0(BAT)-99 s) triggered GBM,\nand the second (from ~T0(BAT)-22 s to ~T0(BAT)+4s), which triggered BAT.\n\nAs observed by Konus-Wind, the burst had a fluence of\n6.09(-0.62,+0.76)x10^-6 erg/cm2 and a 2.944-s peak flux,\nmeasured from ~T0(BAT)-13 s, of 3.10(-0.61,+0.65)x10^-7 erg/cm2/s\n(both in the 20 - 1000 keV energy range).\n\nFitting the K-W 3-channel time-integrated spectrum\n(measured from ~T0(BAT)-108 s to ~T0(BAT)+4 s)\nby a simple power-law model yields the photon index\n-2.20(-0.10,+0.10), chi2=0.88/1 dof.\n\nModelling the 3-channel spectrum near the peak count rate\n(from ~T0(BAT)-13 s to ~T0(BAT)-10 s)\nby the cutoff power law yields the following model parameters:\nthe photon index alpha = -1.62(-0.31,+0.92),\nand the peak energy Ep = 107(-40,+100) keV.\n\nAll the quoted errors are estimated at the 1 sigma confidence level.\nAll the presented results are preliminary.\n\nThe K-W light curve of this burst is available at\nhttp://www.ioffe.rssi.ru/LEA/GRBs/GRB150527A/",
