A Coronal Mass Ejection Source Region Catalog and Their Associated Properties
The Astrophysical Journal Supplement Series, 2023 The primary objective of this study is to connect coronal mass ejections (CMEs) to their source regions, primarily to create a CME source region catalog, and secondarily to probe the influence that the source regions have on the different statistical ...

History and development of coronal mass ejections as a key player in solar terrestrial relationship [PDF]
Geoscience Letters, 2016 Coronal mass ejections (CMEs) are relatively a recently discovered phenomenon—in 1971, some 15 years into the Space Era. It took another two decades to realize that CMEs are the most important players in solar terrestrial relationship as the root cause ...

The Astrophysical Journal Supplement Series, 2023 The origin of cold materials identified by different criteria is unclear. They are highly suspected to be erupted prominences. However, some cold materials defined by charge depletion exist in both quiet solar wind and interplanetary coronal mass ...

STOCHASTICITY AND PERSISTENCE OF SOLAR CORONAL MASS EJECTIONS
The Astrophysical Journal, 2013 The study of the statistical properties of coronal mass ejections (CMEs) reveals that their properties depend on the period of solar activity. In particular, when investigating the origin of the waiting time distribution between CMEs, a significant departure from a Poisson process during periods of high solar activity has been found, thus suggesting ...

Spatial Relationship between Solar Flares and Coronal Mass Ejections [PDF]
The Astrophysical Journal, 2008 We report on the spatial relationship between solar flares and coronal mass ejections (CMEs) observed during 1996-2005 inclusive. We identified 496 flare-CME pairs considering limb flares (distance from central meridian > 45 deg) with soft X-ray flare size > C3 level. The CMEs were detected by the Large Angle and Spectrometric Coronagraph (LASCO)

WHAT CAN WE LEARN ABOUT SOLAR CORONAL MASS EJECTIONS, CORONAL DIMMINGS, AND EXTREME-ULTRAVIOLET JETS THROUGH SPECTROSCOPIC OBSERVATIONS? [PDF]
, 2012 Solar eruptions, particularly coronal mass ejections (CMEs) and extreme-ultraviolet (EUV) jets, have rarely been investigated with spectroscopic observations.

Short term Variability of the Sun Earth System: An Overview of Progress Made during the CAWSES II Period [PDF]
, 2015 This paper presents an overview of results obtained during the CAWSES II period on the short term variability of the Sun and how it affects the near Earth space environment. CAWSES II was planned to examine the behavior of the solar terrestrial system as
