S.Mereghetti, A.Paizis (IASF- Milano), D.Gotz (CEA-Saclay), E. Bozzo,
I.Vovk, M. Beck (ISDC, Versoix), and J. Borkowski (CAMK, Torun) on behalf
of the IBAS Localization Team report:
a short gamma ray burst triggered the IBAS detection programs of the
IBIS/ISGRI data at 17:43:37.4 UT on July 3rd.
The trigger significance was below the threshold for automatic alert
distribution. Off-line interactive analysis confirmed that the trigger is
most likely due to a short GRB, consisting of a single peak with a
duration of about 70 ms. Its refined coordinates (J2000) are:
RA: 9.522 [deg]
DEC: -25.710 [deg]
with an uncertainty of 2.8 arcmin (90% c.l.).
A preliminary analysis gives a fluence in the 20-200 keV range of about
7 10e-7 erg/cmsq (70 ms integration time).
A plot of the light curve will be posted at
