S.Mereghetti, A.Paizis (IASF- Milano), D.Gotz (CEA-Saclay), E. Bozzo, C.
Ricci, M. Beck (ISDC, Versoix), and J. Borkowski (CAMK, Torun) on behalf
of the IBAS Localization Team report:
a gamma ray burst lasting about 60 s has been detected by IBAS in the
IBIS/ISGRI data at 09:04 U.T. on September 9th. The detection
significance was slightly below the threshold for automatic alert
delivery.
Its refined coordinates (J2000) are:
RA: 73.9506 [degrees]
DEC: 54.6544 [degrees]
with an uncertainty of 2 arcmin (90% c.l.).
A preliminary analysis gives a 20-200 keV fluence of about 10e-6 erg/cmsq.
A plot of the light curve will be posted at
