C. Guidorzi, E. Montanari, F. Frontera (Department of Physics, University of Ferrara, Italy) and M. Feroci (IAS/CNR, Rome) on behalf of a larger collaboration report: "With reference to the GRB000528 occurred on May 28.366 UT and localized with the BeppoSAX WFC no. 2 (see BeppoSAX Mails ## 00/10 and 00/11), a preliminary analysis of the GRBM data shows a complex time profile of this GRB with two main peaks of decreasing intensity. The peak flux is of 1.7E3 cts/s in the 40-700 keV energy band corresponding to 1.44 +/- 0.04) x 10^(-6) erg/cm2/s . The GRB duration is of about 80 s. A preliminary spectral analysis reveals an evident softening evolution with an average power law photon index of about 1.9. We are now able to derive rough GRB positions from the GRBM data. The GRBM position obtained for this GRB is R.A.(2000)= 160 and DEC(2000) = -29 with an error radius of 5 deg, that is fully consistent with that given with the WFC." This message is citable.
