(ISDC) on behalf of the IBAS Localization Team report:
A 20 s long GRB has been detected with the INTEGRAL Burst Alert System
(IBAS) on August 12 at 06:01:50 UT. The GRB has been detected with
IBIS/ISGRI in the 15-200 keV band (IBAS Alert # 1901)
Its coordinates (J2000) are:
R.A. 16h 26m 05s
Dec. -44deg 42' 32''
with an uncertainty of 2 arcmin (90% c.l. radius)
The preliminary peak flux in the 20-200 keV range is about 0.6
photons/cmsq/s (5E-8 erg/cmsq/s) (1 s integration time).
A preliminary spectral analysis inidcates that this event is X-ray rich.
