Cline,\non behalf of the Konus-Wind team, report:\n\nThe long-duration GRB 130727A\n(Swift-BAT trigger 564342: Stroh, et al., GCN 15046)\ntriggered Konus-Wind at T0=60324.015 s UT (16:45:24.015)\n\nThe light curve shows multiple overlapping peaks from ~T0-2 s to ~T0+12 s.\nThe emission is seen up to ~6 MeV.\n\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB130727_T60324/\n\nAs observed by Konus-Wind, the burst\nhad a fluence of (9.0 � 1.1)x10-6 erg/cm2,\nand a 64-ms peak flux, measured from T0+0.064 s,\nof (2.9 � 0.4)x10-6 erg/cm2/s\n(both in the 20 keV - 10 MeV energy range).\n\nThe time-averaged spectrum (measured from T0 to T0+8.448 s)\nis best fit in the 20 keV - 18 MeV range\nby the GRB (Band) function with the following model parameters:\nthe low-energy photon index alpha = -1.23 � 0.22,\nthe high energy photon index beta = -2.21 � 0.12,\nthe peak energy Ep = 113 � 22 keV,\nchi2 = 116/97 dof.\n\nAll the quoted results are preliminary.",
