TITLE: GCN GRB OBSERVATION REPORT NUMBER: 3152 SUBJECT: Konus-Wind observation of GRB 050326 DATE: 05/03/28 10:32:11 GMT FROM: Dmitry Frederiks at Ioffe Institute S. Golenetskii, R.Aptekar, E. Mazets, V. Pal'shin, D. Frederiks, and T. Cline on behalf of the Konus-Wind team report: A bright long multipeak GRB 050326 (Swift-BAT trigger 111453, GCN 3143) triggered Konus-Wind at 35633.347 s UT (09:53:53.347). As observed by Konus-Wind, it had a duration of ~38 s, fluence (3.22 ± 0.05)10-5 erg/cm2, peak flux (6.0 ± 0.3)10-6 erg/cm2 s (both in the 20 keV - 3 MeV energy range). Time-integrated spectrum of the burst is fitted with the GRB (Band) model. The low-energy photon index is alpha = -0.74 ± 0.09, the high energy photon index beta = -2.49 ± 0.16, and the break energy E0 = 160 ± 22 keV. The peak energy is Ep = 201 ± 24 keV.
