TITLE: GCN CIRCULAR NUMBER: 12249 SUBJECT: Konus-Wind observation of GRB 110802A DATE: 11/08/04 17:48:43 GMT FROM: Dmitry Frederiks at Ioffe Institute S. Golenetskii, R.Aptekar, D. Frederiks, E. Mazets, V. Pal'shin, P. Oleynik, M. Ulanov, D. Svinkin, and T. Cline on behalf of the Konus-Wind team, report: The short extremely hard GRB 110802A (localized by IPN: Hurley et al., GCN 12247) triggered Konus-Wind at T0=55156.191s UT (15:19:16.191) The burst light curve shows a single double-peaked pulse, the total duration of the burst is ~0.6 s. The emission is seen up to ~10 MeV. The Konus-Wind light curve of this GRB is available at http://www.ioffe.ru/LEA/GRBs/GRB110802_T55156/ As observed by Konus-Wind the burst had a fluence of (1.3 ± 0.3)x10-5 erg/cm2, and a 16-ms peak flux, measured from T0-0.032 s, of (5.0 ± 1.6)x10-5 erg/cm2/s (both in the 20 keV - 10 MeV energy range). The spectrum of the burst (measured from T0 to T0+0.256 s) is best fitted in the 20 keV - 10 MeV range by a power law with exponential cutoff model, for which alpha = -0.63 (-0.25, +0.31), and Ep = 3451(-1086, +2256) keV, chi2 = 24.0/24 dof. All the quoted results are preliminary. All the quoted errors are at the 90% confidence level.
