GCN 18209) has been detected by IBAS in the \nIBIS/ISGRI data with a significance slightly below the threshold for \nautomatic alert delivery (IBAS Weak Alert n.7228 was distributed at \n10:34:24 UT).\n\nThe burst consists of a single peak with duration of 2 s and starting at \n10:34:12 UT.\n\nThe IBIS/ISGRI refined coordinates (J2000) are:\n\nR.A.= 221.0207 deg\nDEC.= -25.6474 deg\n\nwith an uncertainty of 3   arcmin (90% c.l.).\n\nThe burst had a fluence of about 3x10e-7 erg/cm2 in the the 20-200 keV \nenergy range.\n\nA plot of the light curve will  be posted at\nhttp://ibas.iasf-milano.inaf.it/IBAS_Results.html",
