  "body": "S.Mereghetti (INAF, IASF-Milano), D.Gotz (CEA, Saclay), C.Ferrigno, E.Bozzo, V.Savchenko (ISDC, Versoix), L.Ducci (IAAT, Germany and ISDC, Versoix) and J.Borkowski (CAMK, Torun) report:\n\na gamma ray burst lasting about 190 s has been detected by IBAS in the  IBIS/ISGRI data at 16:43:30  UT of 2024 Jan 15. The burst was detected at a large off-axis angle (about 13 degrees)  resulting in a low significance and large uncertainties. We note that the brightest part of the burst was also detected by the Fermi/GBM (GCN circ. 35540)\n\nThe refined coordinates (J2000) are:\nR.A.= 191.894 deg\nDEC.= -35.566 deg\nwith an uncertainty of 3.5 arcmin (90% c.l.).\n\nThe burst had a  fluence of about 4e-6  erg/cmq in the 20-200 keV range.\n\nA plot of the light curve will be posted at \nhttp://ibas.iasf-milano.inaf.it/IBAS_Results.html\n"
