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 4 s has been detected by IBAS in the IBIS/ISGRI data at 05:53:58 UT of 2024 November 20.
The refined coordinates (J2000) are:
R.A.= 194.2908 deg,
DEC.= 52.1504 deg
with an uncertainty of 1 arcmin (90% c.l.).
A preliminary analysis gives a peak flux of about 2 ph/cm2/s (20-200 keV, 1-s integration time) and a fluence in the same energy range of about 1.3e-06 erg/cmsq.
This burst has also been detected by Fermi/GBM (GCN 38279), and its position is at 2.7° from the Fermi reported position.
A plot of the light curve will be posted at
