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 23:46:40 UT of September 19, 2019.
The refined coordinates (J2000) are:
R.A.= 311.8862 deg
DEC.= -44.7029 deg
with an uncertainty of 1.5 arcmin (90% c.l.).
The burst had a peak flux of 0.6 ph/cm2/s (20-200 keV, 1-s integration
time) and a fluence in the same energy range of about 3e-7 erg/cm2.
A plot of the light curve will be posted at
