摘要
Located close to the ecliptic at 5.4 AU heliocentric distance, Ulysses observed energetic particle increases in April/May 1998 that were related to the second major episode of activity in the new solar cycle, the first being in November, 1997. In this paper. we report on the characteristics of the transient particle enhancements seen at Ulysses, including the compositional signatures, and suggest an interpretation in terms of the activity occurring at the Sun.
