Localization Team report:

a long gamma ray burst lasting about 12 s has been detected by IBAS in the 
IBIS/ISGRI data at 13:23:45 UT of August 21

Its refined   coordinates (J2000) are:

RA:   255.2692    [degrees]
DEC:  -40.5212   [degrees]

with an uncertainty of 2 arcmin (90% c.l.).

The burst has a fluence of about  3e-7 erg/cm2  (20-200 keV)

A plot of the light curve will be  posted at
