TITLE: GCN CIRCULAR NUMBER: 17136 SUBJECT: Konus-Wind observation of GRB 141202A DATE: 14/12/04 18:01:42 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 short-duration, hard-spectrum GRB 141202A (IPN triangulation: Golenetskii et al., GCN 17131; Fermi GBM detection: Roberts, GCN 17133) triggered Konus-Wind at T0=40626.305 s UT (11:17:06.305). The burst light curve shows a single pulse with a duration of ~1.4 s. The emission is seen up to ~10 MeV. As observed by Konus-Wind, the burst had a fluence of 4.44(-1.02,+1.47)x10^-6 erg/cm2, and a 16-ms peak flux, measured from T0+0.624 s, of 7.37(-2.00,+2.67)x10^-6 erg/cm2/s (both in the 20 keV - 10 MeV energy range). The time-integrated spectrum of the burst (measured from T0 to T0+8.448 s) is best fit in the 20 keV - 10 MeV range by a power law with exponential cutoff model: dN/dE ~ (E^alpha)*exp(-E*(2+alpha)/Ep) with alpha = -0.49(-0.35,+0.47), and Ep = 538(-150,+274) keV (chi2 = 77/84 dof). Fitting by a GRB (Band) model yields the same alpha and Ep, and an upper limit on the high energy photon index: beta < -2.0 (chi2 = 77/83 dof). The Konus-Wind light curve of this GRB is available at http://www.ioffe.ru/LEA/GRBs/GRB141202_T40626/ All the quoted errors are at the 90% confidence level. All the quoted values are preliminary.
