The short hard GRB 110705A (Fermi/GBM trigger 331529833 / 110705151:
von Klienin, GCN 12108; localized by IPN: Golenetskii et al., GCN 12110)
triggered Konus-Wind at T0=13029.942s UT (03:37:09.942)
The burst light curve shows double-peaked pulse
with a total duration of ~0.25 s.
The emission is seen up to ~5 MeV.
The Konus-Wind light curve of this GRB is available at
As observed by Konus-Wind the burst
had a fluence of (6.0 � 1.0)x10-6 erg/cm2,
and a 16-ms peak flux, measured from T0+0.144 s,
of (3.7 � 0.9)x10-5 erg/cm2/s
(both in the 20 keV - 5 MeV energy range).
The time-integrated spectrum of the burst
(from T0 to T0+0.256 s) is best fitted
in the 20 keV - 5 MeV range by the GRB (Band)
model, for which:
the low-energy photon index alpha = -0.14 (-0.28, +0.37),
the high energy photon index beta = -2.7 (<-2.1),
the peak energy Ep = 820(-146, +205) keV,
chi2 = 20.9/30 dof.
All the quoted results are preliminary.
All the quoted errors are at the 90% confidence level.
