TITLE: GCN CIRCULAR NUMBER: 13707 SUBJECT: Konus-Wind observation of GRB 120830A DATE: 12/08/31 10:57:46 GMT FROM: Dmitry Frederiks at Ioffe Institute S. Golenetskii, R.Aptekar, D. Frederiks, E. Mazets, V. Pal'shin, P. Oleynik, M. Ulanov, D. Svinkin, and T. Cline on behalf of the Konus-Wind team, report: The short-duration hard-spectrum GRB 120830A (Fermi-LAT detection: Vianello et al., GCN 13704; IPN localization: Hurley at al., GCN 13705) triggered Konus-Wind at T0=25623.562s UT (07:07:03.562) The light curve shows a single pulse with a duration of ~0.9 s. The emission 2is seen up to ~5 MeV. The Konus-Wind light curve of this GRB is available at http://www.ioffe.ru/LEA/GRBs/GRB120830_T25623/ As observed by Konus-Wind the burst had a fluence of 4.8(-0.7,+1.1)x10-6 erg/cm2, and a 16-ms peak flux, measured from T0+0.080 s, of 1.6(-0.5,+0.5)x10-5 erg/cm2/s (both in the 20 keV - 10 MeV energy range). The spectrum of the burst (measured T0 to T0+0.256 s) is best fit in the 20 keV - 6 MeV range by a power law with exponential cutoff model, for which alpha = 0.25 (-0.35, +0.45), and Ep = 1070(-200, +240) keV, chi2 = 27/22 dof. All the quoted results are preliminary. All the quoted errors are at the 90% confidence level.
