TITLE: GCN CIRCULAR
NUMBER: 23465
SUBJECT: GRB 181127A : a long GRB detected by INTEGRAL
DATE: 18/11/27 10:36:54 GMT
FROM: Sandro Mereghetti at IASF-Milano/INAF
S.Mereghetti (INAF, IASF-Milano), D.Gotz (CEA, Saclay), 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 15 s has been detected by IBAS in the
IBIS/ISGRI data at 06:46:20 UT of November 27, 2018. The burst was
detected with a significance below the threshold for automatic alert
delivery (IBAS Weak Alert n.8167 was distributed at
06:46:50 UT).
The refined coordinates (J2000) are:
R.A.= 285.3433 deg
DEC.= 31.6895 deg
with an uncertainty of 2.5 arcmin (90% c.l.).
The burst had a peak flux of 0.5 counts/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 is posted at
