[6.08] Association between CME/Flare Events and Enhanced Oxygen Charge States

A. A. Reinard, K. Dere, R. Howard (Naval Research Laboratory)

We present results from a study of coronal mass ejection (CME) data obtained both optically (from SOHO/LASCO and SOHO/EIT) and in situ (from ACE). Phenomena associated with optical CMEs, such as flares and radio bursts, are compared with heliospheric CME signatures, such as enhanced charge states and elevated helium densities, to determine if there is any correspondence between them. A casual relationship has been seen between CMEs with large flares and ICMEs with enhanced oxygen charge state ratios. This relationship will be further investigated. An understanding of how CME observations at the Sun relate to CME observations in the heliosphere will increase our understanding of CME dynamics and may provide insight into CME origins.
