TITLE: GCN CIRCULAR NUMBER: 11342 SUBJECT: Konus-Wind observation of GRB 101014A DATE: 10/10/15 11:45:11 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 very long bright GRB 101014A (Fermi/GBM trigger 308722314 / 101014175: Tierney & Goldstein, GCN 11341) triggered Konus-Wind at T0=15115.250s UT (04:11:55.250) The burst light curve shows a complex multi-peaked structure with a total duration of ~480 s. The emission is seen up to ~10 MeV. The Konus-Wind light curve of this GRB is available at http://www.ioffe.ru/LEA/GRBs/GRB101014_T15115/ As observed by Konus-Wind the burst had a fluence of (2.5 ± 0.7)x10-4 erg/cm2, and a 256-ms peak flux, measured from T0+208.896s, of (2.6 ± 0.2)x10-5 erg/cm2/s (both in the 20 keV - 10 MeV energy range). The time-integrated spectrum of the burst (measured from T0 to T0+445.184 s) is best fit in the 20 keV - 10 MeV range by the GRB (Band) model, for which: the low-energy photon index alpha = -1.26 (-0.13, +0.15), the high energy photon index beta = -2.2 (-1.4, +0.2), the peak energy Ep = 220(-47, +76)keV (chi2 = 64/84 dof). The spectrum at the maximum count rate (measured from T0+208.128 to T0+210.176 s) is best fit in the 20 keV - 10 MeV range by the GRB (Band) model, for which: the low-energy photon index alpha = -1.12 (-0.05, +0.06), the high energy photon index beta = -2.45 (-0.65, +0.30), the peak energy Ep = 920(-170, +180)keV (chi2 = 79/69 dof). All the quoted results are preliminary. All the quoted errors are at the 90% confidence level.
