IBAS Localization Team report:
GRB 150831A (Lien et al. GCN 18209) has been detected by IBAS in the
IBIS/ISGRI data with a significance slightly below the threshold for
automatic alert delivery (IBAS Weak Alert n.7228 was distributed at
10:34:24 UT).
The burst consists of a single peak with duration of 2 s and starting at
10:34:12 UT.
The IBIS/ISGRI refined coordinates (J2000) are:
R.A.= 221.0207 deg
DEC.= -25.6474 deg
with an uncertainty of 3 arcmin (90% c.l.).
The burst had a fluence of about 3x10e-7 erg/cm2 in the the 20-200 keV
energy range.
A plot of the light curve will be posted at
