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 http://ibas.iasf-milano.inaf.it/IBAS_Results.html This message can be cited.
