The Genesis of an Impulsive Coronal Mass Ejection observed at Ultra-High Cadence by AIA on SDO
Impulsive Coronal Ultra-High Cadence AIA on SDO
2011/1/11
The study of fast, eruptive events in the low solar corona is one of the science objectives of the Atmospheric Imaging Assembly (AIA) imagers on the recently launched Solar Dynamics Observatory (SDO),...
Sigmoid-to-Flux-Rope Transition Leading to A Loop-Like Coronal Mass Ejection
Sun flares—Sun Coronal mass ejections (CMEs)—Sun filaments prominences

Solar coronal mass ejections (CMEs) are the most significant drivers of adverse space weather at Earth, but the physics governing their propagation through the heliosphere is not well understood. Whil...
Evidence for a current sheet forming in the wake of a Coronal Mass Ejection from multi-viewpoint coronagraph observations
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
Ray-like features observed by coronagraphs in the wake of Coronal Mass Ejections (CMEs) are sometimes interpreted as the white light counterparts of current sheets (CSs) produced by the eruption.
