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

A Semi-empirical Approach to the Dynamic Coupling of CMEs and Solar Wind
TL;DR: In this paper , the authors deduce expressions to approximate the main forces that affect the dynamic coupling between CMEs and the surrounding solar wind from a magnetohydrodynamic perspective, combined with a few reasonable assumptions, allowing them to obtain expressions for the thermal and magnetic pressure forces, viscous and dynamic drag, and gravity.

Solar Energetic Particle Forecasting Algorithms and Associated False Alarms
TL;DR: A new forecasting algorithm is defined which uses a combination of CME and flare parameters, and it is shown that the false-alarm ratio is similar to that for the algorithm based upon fast CMEs, but the percentage of SEP events not forecast is reduced to 32.4%.

An Insight into the Coupling of CME Kinematics in Inner and Outer Corona and the Imprint of Source Regions
TL;DR: In this article, a follow-up statistical study of several 3D kinematic parameters of 59 CMEs studied by Majumdar et al. was conducted, where the source regions were identified and classified as Active Regions (ARs), Active Prominences (APs), and Prominence Eruptions (PEs).

Magnetic helicity and free magnetic energy as tools for probing eruptions in two differently evolving solar active regions
TL;DR: In this paper , the instantaneous relative magnetic helicity and free magnetic energy budgets for several days in two solar active regions (ARs), AR11890 and AR11618, were calculated using vector magnetograms from the HMI/SDO and a magnetic connectivity-based method.
