Abstract:
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.
