S.Mereghetti (INAF, IASF-Milano), D.Gotz (CEA, Saclay), E.Bozzo,
C.Ferrigno, V.Savchenko (ISDC, Versoix), L.Ducci (IAAT, Germany and ISDC,
Versoix) and J.Borkowski (CAMK, Torun) report:
a gamma ray burst lasting about 20 s has been detected by IBAS in the
IBIS/ISGRI data at 18:48:30 UT of August 28, 2019.
The refined coordinates (J2000) are:
R.A.= 251.9247 deg
DEC.= -24.5498 deg
with an uncertainty of 2.5 arcmin (90% c.l.).
The burst had a peak flux of 0.7 counts/cm2/s (20-200 keV, 1-s
integration time) and a fluence in the same energy range of about 7e-7
erg/cmq.
A plot of the light curve will be posted at
