We present observations during the time period around the large CME event on May 2-3, 1998, of particles with suprathermal energies in the range from 5 to 660 keV/amu. Data from the STOF and HSTOF instruments of the CELIAS experiment on board SOHO are used to study the charge state distribution of He, CNO, the Ne-Mg-Si group, and Fe, the energy spectra of H, He++ and He+ and the variations in the elemental abundance ratios He/H and Fe/O.
