S.Mereghetti, A. Paizis (IASF- Milano), D.Gotz (CEA-Saclay), E. Bozzo,
C.Ferrigno, P. Bordas, M. Beck (ISDC, Versoix), and J. Borkowski (CAMK,
Torun) on behalf of the IBAS Localization Team report:
a long gamma ray burst has been detected by IBAS in the IBIS/ISGRI data at
11:33:35 U.T. on May 18th. It has a FRED light curve lasting about 30 s.
Its refined coordinates (J2000) are:
R.A.: 304.7999 [deg]
DEC.: -24.5609 [deg]
with an uncertainty of 1.6 arcmin (90% c.l.).
A preliminary analysis gives a peak flux in the 20-200 keV range of about
0.5 ph/cmsq/s (1 s integration time) and a fluence over the same energy
range of about 5 10e-7 erg/cmsq.
A plot of the light curve will be posted at
