TITLE: GCN CIRCULAR NUMBER: 5890 SUBJECT: Konus-Wind observation of GRB 061201 DATE: 06/12/02 17:42:07 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 short hard GRB 061201 (Swift-BAT trigger #241840; Marshall et al., GCN 5881; Markwardt et al., GCN 5882) triggered Konus-Wind at T0=57514.558 s UT (15:58:34.558). As observed by Konus-Wind it had a duration of ~0.6 s, fluence 5.33(-4.44, +0.70)x10^-6 erg/cm2, the 16-ms peak flux measured from T0+0.528 3.19(-2.72, +0.72)x10^-5 erg/cm2/s (both in the 20 keV - 3 MeV energy range). The time-integrated spectrum of the GRB (from T0 to T0+8.448 s) is well fitted (in the 20 keV - 3 MeV range) by a power law with exponential cutoff model: dN/dE ~ E^(-alpha) * exp(-(2-alpha)*E/Ep) with alpha = 0.36(-0.65, +0.40) and Ep = 873(-284, +458) keV (chi2 = 79/67 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/GRB061201_T57514/
