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

CME Flux Rope and Shock Identifications and Locations: Comparison of White Light Data, Graduated Cylindrical Shell Model, and MHD Simulations
TL;DR: In this paper, the authors applied the graduated cylindrical shell (GCS) model to fit a flux rope to the CME directed toward STEREO A after about 19:00 UT on 29 November 2013 and check the quality of the heliocentric distance-time evaluations by carrying out a three-dimensional magnetohydrodynamic (MHD) simulation of the same CME with the Block Adaptive Tree Solar-Wind Roe Upwind Scheme (BATS-RUS) code.

3D stereoscopic analysis of a Coronal Mass Ejection and comparison with UV spectroscopic data
TL;DR: In this article, a 3D reconstruction of the 2007, May 20 partial-halo Coronal Mass Ejection (CME) has been made using STEREO/EUVI and Stero/COR1 coronagraphic images, where the trajectory and kinematics of the erupting filament were derived from EUVI image pairs with the tie-pointing triangulation technique, while the polarization ratio technique has been applied to COR1 data to determine the average position and depth of the CME front along the line of sight.

Four Distinct Pathways to the Element Abundances in Solar Energetic Particles
TL;DR: Based on recent evidence from abundance patterns of chemical elements in solar energetic particles (SEPs), and, ironically, the belated inclusion of H and He, the authors can distinguish four basic SEP populations: (1) SEP1 - pure "impulsive" SEPs are produced by magnetic reconnection in solar jets showing steep power-law enhancements of 1<= Z <= 56 ions versus charge-to-mass ratio A/Q from a ~3 MK plasma.

TL;DR: In this paper, the authors used a combination of wavelengths for the removal of the flare component of the irradiance light curve in the cooler coronal emission using simultaneous measurements of warmer coronal lines.
