TITLE: GCN CIRCULAR NUMBER: 17148 SUBJECT: Konus-Wind observation of GRB 141130A DATE: 14/12/08 13:10:46 GMT FROM: Anastasia Tsvetkova at Ioffe Institute S. Golenetskii, R.Aptekar, D. Frederiks, V. Pal'shin, P. Oleynik, M. Ulanov, D. Svinkin, A. Tsvetkova, A.Lysenko, and T. Cline, on behalf of the Konus-Wind team, report: The long GRB 141130A (Swift-BAT trigger #620090: Vargas et al., GCN 17120; Lien et al., GCN 17127) was detected by Konus-Wind in the waiting mode. The burst light curve shows a double-peaked structure with a total duration of ~85 s (from ~T0(BAT)-44 s to ~T0(BAT)+41 s). As observed by Konus-Wind, the burst had a fluence of 8.79(-2.39,+2.62)x10^-6 erg/cm2 and a 2.944 s peak flux, measured from ~T0(BAT)-2.725 s, of 2.40(-0.82,+0.87)x10^-7 erg/cm2/s (both estimated in the 20 keV - 10 MeV energy range). Modeling the KW 3-channel time-integrated spectrum (from T0(BAT)-43.941 s to T0(BAT)+41.435 s) by a power law with exponential cutoff model: dN/dE ~ (E^alpha)*exp(-E*(2+alpha)/Ep) yields alpha =-1.49 ± 0.18, and Ep =307(-108,+467) keV. The K-W light curve of this burst is available at http://www.ioffe.ru/LEA/GRBs/GRB141130A/ All the quoted errors are at 1 sigma confidence level. All the quoted values are preliminary.
