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

Double Superposed Epoch Analysis of Geomagnetic Storms and Corresponding Solar Wind and IMF in Solar Cycles 23 and 24
TL;DR: The weakest solar cycle 24 (SC24, 2010-2019) in 100 years was 1/3rd less active compared to the previous solar cycle 23 (SC23, 1996-2009) as discussed by the authors .

Polarization of the charge-exchange X-rays induced in the Heliosphere
Marko Gacesa,Marko Gacesa,Hans-Reinhard Müller,Robin Côté,Vasili Kharchenko,Vasili Kharchenko +5 more
TL;DR: In this article, a theoretical investigation of the X-ray emissions induced by charge exchange collisions of fully stripped solar wind ions with the heliospheric hydrogen atoms was performed, and the authors predicted the polarization of charge exchange X-rays to be between 3% and 8%, depending on the line-of-sight geometry, solar wind ion velocity, and selected emission lines.
