S.Mereghetti (IASF-Milano), D.Gotz (CEA, Saclay), C.Ferrigno, E.Bozzo, 
E.Filippova (ISDC, Versoix), and J.Borkowski (CAMK, Torun) on behalf of 
the IBAS Localization Team report:

a gamma ray burst lasting about 100 s has been detected by IBAS in the 
IBIS/ISGRI data at 09:26:00 UT of March 20.

The refined coordinates (J2000) are:

R.A.=  145.5409 deg
DEC.=  +60.2794 deg

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

A preliminary analysis gives a peak flux of 0.2 counts/cm2/s (20-200 keV, 
1-s integration time) and a fluence in the same energy range of about 5e-7 
erg/cmq.

A plot of the light curve will be posted at
