D. Gotz (CEA-Saclay), A.Paizis, S.Mereghetti (IASF-Milano), V.Beckmann, M. Beck, R. Galis (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 09:35:21 UT of June 13 2008. The coordinates (J2000) are: RA: 213.2742 [degrees] DEC: +5.1687 [degrees] with an uncertainty of 1.5 arcmin (90% c.l.). A preliminary analysis yields a peak flux integrated over 1 s of about 1.3 ph/cmsq/s (20-200 keV) and a fluence over the same energy range of about 1.3e-6 erg/cmsq. A plot of the light curve will be posted at http://ibas.iasf-milano.inaf.it/IBAS_Results.html This message can be cited.
