TITLE:   GCN CIRCULAR
NUMBER:  37781
SUBJECT: GRB 241013A: a long GRB detected by INTEGRAL

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
