D. Gotz (CEA Saclay), S. Mereghetti (IASF-Milano), E. Bozzo, C. Ferrigno, (ISDC, Versoix), and J. Borkowski (CAMK, Torun) on behalf of the IBAS Localization Team report:
a gamma ray burst lasting about 70 s has been detected by IBAS in the IBIS/ISGRI data at 21:25:01 U.T. on November 22.
Its refined coordinates (J2000) are:
R.A.: 152.5553 deg
DEC.: 57.7398 deg
with an uncertainty of 1.6 arc min (90% c.l.).
The burst had a fluence of about 2x10^-6 erg/cmsq in the 20-200 keV energy band, and a peak flux of 0.4 ph/cmsq/s in the same energy band over 1 s.
A plot of the light curve will be posted at http://ibas.iasf-milano.inaf.it/IBAS_Results.html
