GCN Circular 18623

Subject
GRB 151120A: A long GRB detected by INTEGRAL
Date

From
Sandro Mereghetti at IASF/CNR <sandro@iasf-milano.inaf.it>
S.Mereghetti (IASF-Milano), D.Gotz (CEA, Saclay), C.Ferrigno, E.Bozzo, 
Godze Saral (ISDC, Versoix), and J.Borkowski (CAMK, Torun) on behalf of 
the IBAS Localization Team report:

a gamma ray burst lasting about 50 s has been detected by IBAS in the 
IBIS/ISGRI data at 8:22:50 UT of 2015 November 20.

The refined coordinates (J2000) are:

R.A.=  157.2502 deg
DEC.=  -32.5237 deg

with an uncertainty of   1.5   arcmin (90% c.l.).

The burst saturated the available ISGRI telemetry, therefore we can only 
provide a lower limit for the fluence in the 20-200 keV energy range of 
2e-6 erg/cmq.

A plot of the light curve will  be posted at
