Probing Velocity Dispersion Inside Coronal Mass Ejections: New Insights on Their Initiation
The Astrophysical Journal LettersThis work studies the kinematics of the leading edge and the core of six coronal mass ejections (CMEs) in the combined field of view of Sun Watcher using Active Pixel System detector and Image Processing (SWAP) on board PRoject for On-Board Autonomy ...

Solar Energetic Particles and Radio‐silent Fast Coronal Mass Ejections
The Astrophysical Journal, 2006 Both solar flares and shock waves driven by fast coronal mass ejections (CMEs) can accelerate charged particles in the solar corona and create transient enhancements of solar energetic particle fluxes in interplanetary space (SEP events). Fast CMEs and flares often occur together, which makes it difficult to directly identify the actual source of SEP ...

MMS Observations of a Compressed, Strongly Driven Magnetopause During the 2024 Mother's Day Storm
Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.Abstract From 10 to 12 May 2024, a series of coronal mass ejections led to one of the strongest geomagnetic storms of the century, referred to as the Mother's Day or Gannon Storm. MMS's position on the dayside magnetosphere on 11 May provided observations of a strongly driven and compressed ∼7RE $\left(\sim 7\ {R}_{E}\right)$ reconnecting magnetopause.

Effects of Coronal Mass Ejections on Distant Coronal Streamers
, 2014 The effects of a large coronal mass ejection (CME) on a solar coronal streamer located roughly 90 degrees from the main direction of the CME propagation observed on January 2, 2012 by the SOHO/LASCO coronagraph are analyzed.

The relationship between EUV dimming and coronal mass ejections [PDF]
, 2007 Aims. There have been many studies of extreme-ultraviolet (EUV) dimming in association with coronal mass ejection (CME) onsets. However, there has never been a thorough statistical study of this association, covering appropriate temperature ranges. Thus,
