摘要：
The STEP instrument on the WIND spacecraft observed several upstream events in coincidence with He-3 and Fe-rich solar energetic particle events in late 1994. The distinctive ion composition of the impulsive solar energetic particle population provides an opportunity to study mechanisms that produce upstream events. We report energy spectra and mass composition of both the upstream event ions and SEP ions as well as the first detection of He-3 ions in an upstream event. The detection of He-3 unambiguously demonstrates that salar energetic particles can undergo further acceleration near the Earth.
