Torun), E. Bozzo, C.Ferrigno, M. Beck (ISDC, Versoix), on behalf of the
IBAS Localization Team report:
A short gamma ray burst lasting about 0.5 s has been detected by IBAS in
the IBIS/ISGRI data at 22:24:54.6 UT of January 12.
The detection significance was slightly below the threshold for automatic
alert delivery.
Its refined coordinates (J2000) are:
RA: 10.599 [degrees]
DEC: 64.406 [degrees]
with an uncertainty of 2.6 arcmin (90% c.l.).
A preliminary analysis gives a 20-200 keV fluence of about 1e-7
erg/cm2 and a peak flux of about 5 ph/cm2 s (0.1 s integration time)
A plot of the light curve will be posted at

NOTE: Automatic distribution of sky coordinates of low significance
INTEGRAL IBAS triggers is currently under testing. This service will soon
be made available to the interested users.
