Partially Erupted Prominence Material as a Diagnostic of Coronal Mass Ejection Trajectory

Coronal mass ejections (CMEs) are energetic releases of large-scale magnetic structures from the Sun. CMEs can have impacts on spacecraft and at Earth. This trajectory is typically assumed to be radial, but often CME moves outward with some spatial offset source region where eruption initially occurred. A frequently accompanied by a prominence eruption, movement cool, dense material up into corona that ejected or fall back down. We investigate eruptions in which portion falls Sun along field lines reconfigured rather than draining escaping CME. Using method called persistence mapping, 304 Å images Solar Dynamics Observatory (SDO), coronagraph Heliospheric Observatory, we measure compare offsets latitude 20 their respective prominences respect region.

These findings help us contextualize individual highlight associated eruption.
