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: In this paper, Chandra Advanced CCD Imaging Spectrometer (ACIS-S) observations of the Jovian auroral X-ray spectrum were carried out over 24-26 February 2003 by NASA's Advanced CCS-S instrument over 24 and 26 February 2003, and the results showed that the spectrum consists of line emission consistent with high-charge states of precipitating ions.

Different Power-law Indices in the Frequency Distributions of Flares with and without Coronal Mass Ejections
Seiji Yashiro,Seiji Yashiro,Sachiko Akiyama,Sachiko Akiyama,Nat Gopalswamy,Russell A. Howard +5 more
TL;DR: In this paper, the frequency distributions of CMEs with and without coronal mass ejections (CMEs) as a function of flare parameters (peak flux, fluence, and duration of soft X-ray flares) were investigated and the distributions obey a power-law of the form: dN/dX~X^-alpha, where X is a flare parameter and dN is the number of events recorded within the interval [X, X+dX].

TL;DR: In this paper, the authors tie together physical processes across the full scale of the heliosphere and discuss the natural connections that exist between various parts of the system, but their focus is mainly cast in terms of those mechanisms and phenomena rather than individual missions.
