D.Gotz (CEA, Saclay), S.Mereghetti (INAF, IASF-Milano), C.Ferrigno, E.Bozzo, V.Savchenko (ISDC, Versoix), L.Ducci (IAAT, Germany and ISDC, Versoix) and J.Borkowski (CAMK, Torun) report:
a gamma ray burst lasting about 30 s has been detected by IBAS in the IBIS/ISGRI data at 00:58:26 UT of 2024 October 13.
The refined coordinates (J2000) are:
R.A.= 275.2756 deg
DEC.= -15.6302 deg
with an uncertainty of 2.5 arcmin (90% c.l.).
A preliminary analysis gives a peak flux of about 0.6 ph/cm2/s (20-200 keV, 2-s integration time) and a fluence in the same energy range of about 6e-7 erg/cmsq.
This burst has also been detected by Fermi/GBM (GCN 37780), and its position is at 26.8° from the Fermi reported position.
A plot of the light curve will be posted at
