TITLE: GCN CIRCULAR NUMBER: 7309 SUBJECT: Konus-Wind observation of GRB 080211 DATE: 08/02/13 15:23:54 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 GRB 080211 (Hurley et al., GCN 7295) triggered Konus-Wind at T0=26622.790 s UT (07:23:42.790). As observed by Konus-Wind the burst had a fluence of 4.66(-0.19, +0.20)x10^-5 erg/cm2, and a 64-ms peak flux measured from T0+5.824 s of (6.66 +/- 1.22)x10^-6 erg/cm2/s (both in the 20 keV - 2 MeV energy range). The time-integrated spectrum of the burst (from T0 to T0+27.648 s) can be fitted (in the 20 keV-2 MeV range) by a power law with exponential cutoff model: dN/dE ~ (E^alpha)*exp(-E*(2+alpha)/Ep) with alpha = -0.85 +/- 0.06 and Ep = 356(-22, +25) keV (chi2 = 70.6/62 dof). The spectrum of the most intense part (from T0 to T0+5.888 s) is well fitted (in the same range) by a power law with exponential cutoff model with alpha = -0.67 +/- 0.09 and Ep = 484(-40, +45) keV (chi2 = 53.2/62 dof). Fitting by GRBM (Band) model yields: the low-energy photon index is alpha = -0.61(-0.11, +0.13), the high energy photon index beta = -2.62(-1.48, +0.40), the peak energy Ep = 441(-61, +62) keV (chi2 = 50.0/61 dof). The fluence of this part is (1.81 +/- 0.11)x10^-5 erg/cm2. All the quoted errors are at the 90% confidence level.
