AB: We describe a study of the compositional properties of heliospheric CME ejecta within the context of solar CME observations. In this study, we examine CME-ICME pairs to determine if a given CME is associated with a flare event. For each of these pairs the charge state ratios are averaged over the event and compared. We find that events originating near the central meridian are more likely to contain significantly higher charge state ratios. The charge states in those events are moderately correlated with flare magnitude, indicating that flare material enters or heats a portion of the CME ejecta. We define "central" events based on the enhanced oxygen charge state and average several in situ quantities over the ICME period. We find that plasma quantities tend to be enhanced in both "central" and "limb" events, but composition quantities are enhanced only in "central" events.
