S.Mereghetti, A.Paizis (IASF-Milano), D.Gotz (CEA-Saclay), F. Fontani, 
V.Beckmann, M. Beck (ISDC, Versoix), and J. Borkowski (CAMK, Torun) on 
behalf of the IBAS Localization Team report:

A GRB lasting about 30 s has been detected by IBAS in IBIS/ISGRI data at 
13:46:12 UT of October 3. The coordinates (J2000)  are:

RA = 262.3758 [degrees]
DEC= 16.566 [degrees]

with an uncertainty of 2 arcmin (90% c.l.).

A preliminary analysis gives a peak flux in the 20-200 keV range of about 
0.3 ph/cmq/s (1-s integration time) and a fluence over the same energy 
range of about 4x10e-7 erg/cmq.

A plot of the light curve will be posted at
