TITLE: GCN CIRCULAR NUMBER: 19667 SUBJECT: Konus-Wind observation of GRB 160702A (short/hard) DATE: 16/07/08 20:30:03 GMT FROM: Dmitry Frederiks at Ioffe Institute D. Frederiks, S. Golenetskii, R.Aptekar, P. Oleynik, M. Ulanov, D. Svinkin, A. Tsvetkova, A.Lysenko, A. Kozlova, and T. Cline, on behalf of the Konus-Wind team, report: The short GRB 160702A (IPN triangulation: Hurley et al., GCN 19666) triggered Konus-Wind at T0=44544.054 s UT (12:22:24.054). The light curve shows a short, hard pulse with a total duration of ~200 ms. The emission is seen up to ~5 MeV. As observed by Konus-Wind, the burst had a fluence of (2.5 ± 0.7)x10^-6 erg/cm2 and a 16-ms peak energy flux, measured from T0-0.016, of (3.0 ± 0.4)x10^-5 erg/cm2 (both in the 20 keV - 10 MeV energy range). The spectrum of the burst (measured from T0 to T0+0.128 s) is best fit in the 20 keV - 10 MeV range by a cutoff power-law (CPL) function with the following model parameters: the photon index alpha = -0.28(-0.35,+0.48), and the peak energy Ep = 782(-186,+308) keV, chi2 = 32.3/31 dof. Fitting this spectrum with the GRB (Band) function yields the same alpha and Ep with only an upper limit on beta of -2.1, chi2 = 31.9/30 dof. The Konus-Wind light curve of this GRB is available at http://www.ioffe.ru/LEA/GRBs/GRB160702_T44544/ All the quoted errors are estimated at the 90% confidence level. All the presented results are preliminary.
