Wigger, and W. Hajdas, on behalf of the RHESSI GRB team, report: Fermi (GBM), Konus-Wind, Swift (BAT), MESSENGER (GRNS), and RHESSI observed the very bright GRB 100829A at about 75729 s UT (21:02:09) (the Fermi/GBM trigger 304808530). The burst was outside the coded field of view of the BAT. We have triangulated this burst to the following 3 sigma error box: ----------------------------------------------- RA(2000), deg Dec(2000), deg ----------------------------------------------- Center: 90.409 (06h 01m 38s) +30.314 (+30d 18' 49") Corners: 90.335 (06h 01m 20s) +29.523 (+29d 31' 22") 90.353 (06h 01m 25s) +30.317 (+30d 19' 02") 90.490 (06h 01m 58s) +31.121 (+31d 07' 16") 90.464 (06h 01m 51s) +30.310 (+30d 18' 37") ----------------------------------------------- The error box area is 278 sq. arcmin. The maximum distance between the box corners is 1.6 deg. This error box may be improved.

Circular_text TITLE: GCN CIRCULAR NUMBER: 11204 SUBJECT: Konus-Wind observation of GRB 100829A DATE: 10/09/04 11:13:35 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 bright GRB 100829A, (localized by IPN: Golenetskii et.al, GCN 11199) triggered Konus-Wind at T0=75727.937s UT (21:02:07.937) The burst light curve started with a bright complex ~2.5s-long structure, followed by a weaker emission episode at T0 + 6 s. The total duration of the burst is ~10 s. The emission is seen up to 1.5 MeV. The Konus-Wind light curve of this GRB is available at http://www.ioffe.ru/LEA/GRBs/GRB100829_T75727/ As observed by Konus-Wind the burst had a fluence of (1.40 0.15)x10-5 erg/cm2, and a 16-ms peak flux, measured from T0+1.472s, of (2.4 0.6)x10-5 erg/cm2/s (both in the 20 keV - 2 MeV energy range). The time-integrated spectrum of the burst (from T0 to T0+10.240 s) is best fit in the 20 keV - 2 MeV range by a power law with exponential cutoff model, for which alpha = -1.44(-0.12, +0.14), and Ep = 278(-47, +73) keV (chi2 = 36.2/61 dof). Fitting this spectrum by the GRB (Band) model yields to the same values of alpha and Ep, with beta = -9.4 (<-2.3), chi2 = 36.2/60 dof. The spectrum at the maximum count rate (measured from T0+0.256 to T0+2.048 s) is best fit in the 20 keV - 2 MeV range by the GRB (Band) model, for which: the low-energy photon index alpha = -0.90 (-0.17, +0.35), the high energy photon index beta = -2.7 (<-2.2), the peak energy Ep = 263(-71, +56) keV (chi2 = 48.5/51 dof). All the quoted results are preliminary. All the quoted errors are at the 90% confidence level.
