Solar Energetic Particle Spectra and Composition in the October/November 2003 Events
Abstract
The series of extremely large solar energetic particle (SEP) events of October and November 2003 were well observed by many spacecraft. We have combined data from the ULEIS and SIS instruments on ACE to obtain particle intensities over >3 decades in energy. The event-integrated composition (carbon through iron) not only varies from event to event, but also as a function of energy within an SEP event. These compositional variations are a result of the element-dependent spectral breaks and we suggest they can be substantially reduced when the spectra are examined in terms of rigidity-dependent escape from the shock.
