Zurita Heras (ISDC, Versoix) and J. Borkowski (CAMK, Torun) on behalf of
the IBAS Localization Team report:
A possible GRB triggered IBAS at 13:43:18 UT with coordinates (J2000)
R.A. = 271.1541
Dec. = -32.0235
with an uncertainty of 3.5 arcmin radius (90% c.l.).
The trigger significance was below the threshold for automatic alert delivery.
A preliminary analysis shows a spectrum consistent with an X-ray flash and
a fluence (20-200 keV) is 1E-7 erg/cm^2. However, due to the position in
the galactic bulge and the soft spectrum, we cannot exclude that the
trigger is due to an uncatalogued Galactic source.
