TLDR
The SOHO/LASCO CME catalog as mentioned in this paper is a data base for the analysis of coronal mass ejections (CMEs) in the solar corona.Abstract:
Coronal mass ejections (CMEs) are routinely identified in the images of the solar corona obtained by the Solar and Heliospheric Observatory (SOHO) mission’s Large Angle and Spectrometric Coronagraph (LASCO) since 1996. The identified CMEs are measured and their basic attributes are cataloged in a data base known as the SOHO/LASCO CME Catalog. The Catalog also contains digital data, movies, and plots for each CME, so detailed scientific investigations can be performed on CMEs and the related phenomena such as flares, radio bursts, solar energetic particle events, and geomagnetic storms. This paper provides a brief description of the Catalog and summarizes the statistical properties of CMEs obtained using the Catalog. Data products relevant to space weather research and some CME issues that can be addressed using the Catalog are discussed. The URL of the Catalog is: http://cdaw.gsfc.nasa.gov/CME_list.read more

TL;DR: The Extreme-ultraviolet Stellar Characterization for Atmospheric Physics and Evolution (ESCAPE) mission is an astrophysics Small Explorer employing ultraviolet spectroscopy (EUV: 80 to 825 Å and FUV: 1280 to 1650Å) to explore the high-energy radiation environment in the habitable zones around nearby stars as discussed by the authors .

Global Energetics of Solar Flares: VII. Aerodynamic Drag in Coronal Mass Ejections
TL;DR: In this article, the effects of the aerodynamic drag force on CMEs were explored, and it was shown that the inclusion of the drag force slightly lowers the overall energy budget of CME kinetic energies in flares from approximately 7% to approximately 4%.
Near-Earth Cosmic Ray Decreases Associated with Remote Coronal Mass Ejections
TL;DR: In this article, the authors report on four Forbush decreases observed at ground-based neutron monitors which cannot be immediately associated with significant structures in the local solar wind, while there are significant near-Earth structures which do not produce any corresponding GCR variation.

Statistical characteristics on SEPs, radio-loud CMEs, low frequency type II and type III radio bursts associated with impulsive and gradual flares
TL;DR: In this article, a set of 115 low frequency (Deca-Hectometer wavelengths range) type II and type III bursts associated with major solar Energetic Particle (SEP: Ep > 10 MeV) events and their solar causes such as solar flares and coronal mass ejections (CMEs) observed from 1997 to 2014.

Kinematics of coronal mass ejections in the LASCO field of view
TL;DR: In this article, the authors present a statistical study of the kinematics of 28894 coronal mass ejections (CMEs) recorded by the Large Angle and Spectrometric Coronagraph (LASCO) on board the Solar and Heliospheric Observatory spacecraft from 1996 until mid-2017.
