7513 Coronal Mass Ejections
Scientific paper
Coronal Mass Ejection (CME) trajectories are produced by combining inner coronal white light observations from the Mauna Loa Coronameter with outer coronal observations from the Large Angle Spectroscopic Coronagraphs (LASCO) and cover apparent altitudes from 1.2 to 30 solar radii. Speeds, accelerations and in a few cases the rate of change of acceleration can be determined. Coronagraph observations since Skylab have shown that the speeds and accelerations of CMEs in the corona can vary greatly from event to event. On average, CMEs associated with large, non-active region filament eruptions tend to have lower accelerations than active region associated CMEs. Observations from LASCO and the Solar Maximum Mission (SMM) indicate the fastest ~5 percent of CMEs (speeds above 1000 km/sec) are all active region associated. Different physical mechanisms may be responsible for the acceleration of the fastest CMEs. If so a bimodal distribution of CME kinematic properties may be present. Trajectories from CMEs with and without active region associations are compared to determine the existence of a bimodal distribution. ~
