Localization Team report
A 60 s long GRB has been detected in IBIS/ISGRI data by IBAS (Alert
Number 2587) at 03:45:16 UT. Its coordinates (J2000) are
RA: 186.7445
DEC: -63.1342
with an uncertainty of 2 arcmin (90% c.l.).
The preliminary peak flux is 0.4 ph (3E-8 erg) cmsq/s, while the fluence
is 8.7E-7 erg/cmsq. Both values refer to the 20-200 keV band.
A preliminary spectral analysis shows that this event is X-ray rich.
A light curve will be posted at
