S.Mereghetti, A.Paizis (IASF-Milano), D.Gotz (CEA-Saclay), I.Kreykenbohm, 
N.Mowlavi, M. Beck (ISDC, Versoix), and J. Borkowski (CAMK, Torun) on 
behalf of the IBAS Localization Team report:

A GRB lasting about 50 s has been detected by IBAS in IBIS/ISGRI data on 
March 11 at 01:52:50 UT

The coordinates (J2000)  are:
RA = 87.5411 deg   
DEC = 3.3748 deg

with an uncertainty of 2.5 arcmin (90% c.l.).

Preliminary analysis of the IBIS data indicates a peak flux of 0.9 
photons/cmq s (20-200 keV, 1 s integration time) and a fluence of 2x10e-6 

A plot of the light curve will be posted at
