a gamma ray burst lasting about 30 s has been detected by IBAS in the IBIS/ISGRI data at 13:53:15 UT of 2024 December 15.
The refined coordinates (J2000) are:
R.A.= 10.5861 deg
DEC.= +32.5190 deg
with an uncertainty of 2.5 arcmin (90% c.l.).
The burst had a peak flux of 0.5 ph/cm2/s (20-200 keV, 1-s integration time) and a fluence in the same energy range of about 4e-7 erg/cmq.
A plot of the light curve will be posted at
