Coronal Mass Ejection–Associated Coronal Dimmings
The Astrophysical Journal, 2008 We report on a statistical analysis of 96 CME-associated EUV coronal dimmings between 1998 and 2000. We investigate the size and location of the events and characterize how these events evolve with time. The durations typically range from 3 to 12 hr. The dimmings appear most frequently within the belt of active regions (20°-50° latitude).

Coronal Mass Ejections: Models and Their Observational Basis
Living Reviews in Solar Physics, 2011 Coronal mass ejections (CMEs) are the largest-scale eruptive phenomenon in the solar system, expanding from active region-sized nonpotential magnetic structure to a much larger size.

A Deep Learning Method for Automatic Coronal Mass Ejection Feature Identification
The Astrophysical Journal Supplement SeriesCoronal mass ejections (CMEs), intense solar eruptive phenomena, are the primary drivers of extreme space weather storms on Earth. As space activities become increasingly frequent and infrastructure more reliant on space-based systems, the rapid and ...

The Astrophysical Journal, 2001 Narrow coronal mass ejections (CMEs), defined arbitrarily as events whose apparent angular width is 15° or less, are a small subset of all CMEs. Little is known of the properties of these events and whether these properties differ from those of the larger, more typical CMEs. We have included in this study 15 narrow CMEs observed in the period from 1999

Assessing electron heat flux dropouts as signatures of magnetic field line disconnection from the Sun [PDF]
, 2005 Suprathermal electrons focused along magnetic field lines, called the strahl, carry heat flux away from the Sun. Various factors can cause heat flux dropouts (HFDs), including times when the strahl almost vanishes.

Distorted Magnetic Flux Ropes within Interplanetary Coronal Mass Ejections
The Astrophysical JournalMagnetic flux ropes (MFRs) at the center of interplanetary coronal mass ejections (ICMEs) are often characterized as simplistic cylindrical or toroidal tubes with field lines that twist around the cylinder or torus axis.
