TITLE: GCN CIRCULAR NUMBER: 7263 SUBJECT: Konus-Wind observation of GRB 080204 DATE: 08/02/06 17:11:20 GMT FROM: Valentin Pal'shin at Ioffe Inst S. Golenetskii, R.Aptekar, E. Mazets, V. Pal'shin, D. Frederiks, and T. Cline on behalf of the Konus-Wind team report: The long hard GRB 080204 (Golenetskii et al., GCN 7256) triggered Konus-Wind at T0=50190.835 (13:56:30.835). As observed by Konus-Wind the burst had a fluence of 2.65(-0.47, +0.37)x10^-5 erg/cm2, and a 64-ms peak flux measured from T0-0.032 s of 9.52(-2.49, +2.25)x10^-6 erg/cm2/s (both in the 20 keV - 6 MeV energy range). The time-integrated spectrum of the burst (not including the precursor; from T0 to T0+16.640 s) is well fitted (in the 20 keV - 6 MeV range) by a power law with exponential cutoff model: dN/dE ~ (E^alpha)*exp(-E*(2+alpha)/Ep) with alpha = -1.35(-0.09, +0.06) and Ep = 1279(-382, +469) keV (chi2 = 79.2/78 dof). All the quoted errors are at the 90% confidence level. The Konus-Wind light curve of this GRB is available at http://www.ioffe.rssi.ru/LEA/GRBs/GRB080204_T50190/
