Cline\non behalf of the Konus-Wind team, report:\n\nThe long GRB 091010 (Donnarumma et al., GCN Circ. 10004; Feroci, GCN Circ 10005)\ntriggered Konus-Wind at T0=09788.232 s UT (02:43:08.232).\n\nThe burst light curve shows a multipeaked structure with a total\nduration of ~8 s. The Konus-Wind light curve of this GRB is available\nat http://www.ioffe.ru/LEA/GRBs/GRB091010_T09788/\n\nAs observed by Konus-Wind the burst\nhad a fluence of (9.4 � 1.1)x10-6 erg/cm2,\nand a 64-ms peak flux measured from T0 + 2.240s\nof (8.3 � 1.0)x10-6 erg/cm2/s\n(both in the 20 keV - 2 MeV energy range).\n\nThe time-integrated spectrum of the burst (from T0 to T0+8.448 s)\nis well fitted in the 20 keV - 2 MeV range by GRB (Band) model for which:\nthe low-energy photon index alpha = -1.20 (-0.28, +0.35),\nthe high energy photon index beta = -2.9(< -2.4),\nthe peak energy Ep = 119(-17, +19) keV (chi2 = 55/59 dof).\n\nAll the quoted errors are at the 90% confidence level.",
