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

The Wind /EPACT Proton Event Catalog (1996 – 2016)
TL;DR: In this paper, the authors presented the finalized catalog of solar energetic proton events detected by the Wind/EPACT instrument over the period 1996 to 2016, and the statistical relationships between the energetic protons and their origin were reported and discussed in view of earlier findings.

A Sun-to-Earth analysis of magnetic helicity of the 17-18 March 2013 interplanetary coronal mass ejection
Sanchita Pal,Nat Gopalswamy,Dibyendu Nandy,Sachiko Akiyama,Seiji Yashiro,Pertti Makela,Hong Xie +6 more
TL;DR: Gopalswamy et al. as discussed by the authors derived the magnetic helicity of the flux rope using its magnetic and geometric properties obtained near the Sun and at 1 AU, and found that about 83% of the total flux rope helicity at 1AU is injected by the magnetic reconnection in the low corona.

Yardley,Andrei Zhukov,Andrei Zhukov +26 more
TL;DR: In this paper, the authors focus on the stealthy geomagnetic storms in the sense that the solar/CME precursors are enigmatic and stealthy, and discuss the solar and in situ circumstances of these events and identify several scenarios that may account for their elusive solar signatures.
