The propagation of coronal mass ejection transients
Abstract
Measurements of the direction of propagation of 29 coronal mass ejection events observed during the Skylab epoch (1973-1974) and 19 events observed during the SMM epoch (1980) reveal that the former undergo an average 2.2° equatorward deflection, while the latter do not deviate signficantly from radial motion. No differences between eruptive prominence-associated or flare-associated events can be detected for either epoch. The results suggest that coronal mass ejection events are influenced by the background coronal magnetic and flow patterns; the nonradial forces affecting the Skylab epoch mass ejections arise from the large-scale dipolar magnetic field and flow configuration present at that time.
