Borkowski (CAMK, Torun) on behalf of the \nIBAS Localization Team report:\n\nA long GRB has been detected by IBAS in IBIS/ISGRI data at 08:00:52.5 UT \non May 4. Its coordinates (J2000) are:\n\nRA:  200.9986 [degrees] \nDEC: +40.6959 [degrees]\n\nwith an uncertainty of 1.5 arcmin (90% c.l. radius).\n\nNote that this burst is located at high galactic latitude (b=+75 deg) and \nnot affected by Galactic absorption. It is therefore a good target for \noptical follow-up searches.\n\nAnalysis of the IBIS/ISGRI data yields a peak flux of 0.5 photons (6E-8\nergs)/cmsq/s (1 s integration time) and a fluence of 14.4 photons (1.5E-6 \nergs)/cmsq (80 s integration time). Both values refer to the 20-200 keV energy \nrange.\n\nThe burst lasted about 80 s and had a FRED profile. A plot of the light curve \ncan be found at:\n\nhttp://ibas.mi.iasf.cnr.it/IBAS_Results.html\n\nThis message can be cited.",
