Using ~4 MeV /nucleon solar energetic particle data from the Solar Isotope Spectrometer (SIS) on the Advanced Composition Explorer (ACE), we identify 60 ^3He-rich time periods longer than 5 hours in length. As many of these time periods do not have "classical" impulsive profiles, we classify each event as one of 4 event types (based on the morphology of the event). The time periods have been associated with solar events listed by the Space Environment Center and energetic electron events observed by the Electron, Proton, and Alpha Monitor (EPAM) on ACE. Only half of the events could be associated with an x-ray event and 63% with an electron event.
