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

Plasma heating in a post eruption current sheet: a case study based on ultraviolet, soft, and hard x-ray data
TL;DR: In this article, the authors studied the evolution of plasma heating after the CME of 2004 July 28 by comparing UV spectra acquired by UVCS with soft and hard X-ray (SXR, HXR) images of the post-flare loops taken by GOES/SXI and RHESSI.

Coronal Mass Ejections as a Mechanism for Producing IR Variability in Debris Disks
Rachel A. Osten,Mario Livio,S. H. Lubow,J. E. Pringle,J. E. Pringle,David R. Soderblom,Jeff A. Valenti +6 more
TL;DR: In this article, the authors proposed that coronal mass ejections can remove dust grains on timescales as short as a few days, motivated by recent observations of short-timescale variations in the infrared emission of circumstellar disks.

TL;DR: In this article, the authors compared the solar and interplanetary characteristics of the moderate storms driven by coronal mass ejection (CME) for solar cycles 23 and 24 in order to see reduction in geoeffectiveness has anything to do with the occurrence of moderate storm.
