The burst GRB 241107A, detected by SVOM/GBM (Wang et al. GCN Circ. 38125), INTEGRAL/IBIS-PICsIT (Rodi et al., GCN 38164), Swift/BAT, Konus-Wind and INTEGRAL/SPI-ACS (Kozyrev et al., GCN Circ. 38165) was located in the coded field of view of the IBIS instrument, but it was too faint to trigger IBAS.
The burst was detected in the IBIS/ISGRI data at 23:30:00.2 UT of November 7, 2024
A preliminary analysis indicates a duration of about 0.2 s, a fluence of about 3e-8 erg/cm2 (20-200 keV) and the following coordinates (J2000): R.A.= 111.312 deg DEC.= -24.496 deg with an uncertainty of 5 arcmin (90% c.l.).
