report on behalf of the BeppoSAX/GRBM Team:
"From the high time resolution data the GRBM lightcurve shows a global
three peak structure, with minor (~20-30 ms) structures within
each peak. The time-resolved spectral analysis shows a weak spectral
evolution. The time-averaged spectral power law photon index in the
40-700 keV energy range is (2.1+-0.3).
The peak flux and fluence in the same band are (2.4 +/- 0.4)e-6 ergs/cm2/s
and (1.0+/-0.2)e-5 ergs/cm2, respectively. Please note that the latter
value corrects a typo occurred in Feroci et al. (GCN 159)."
