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 Statistical Study on CMEs Associated with DH-Type-II Radio Bursts Based on Their Source Location (Limb and Disk Events)
TL;DR: In this paper, Gopalswamy et al. compared the CME properties between limb and disk events and found a better correlation between CME speed and width (correlation coefficient R=0.56) for the limb events than that of the disk events.

Estimation of Arrival Time of Coronal Mass Ejections in the Vicinity of the Earth Using SOlar and Heliospheric Observatory and Solar TErrestrial RElations Observatory Observations
TL;DR: In this article, the authors defined a new initial velocity of the CME, the maximum velocity determined from the velocity profiles obtained from a moving linear fit to five consecutive height-time points.

TL;DR: It is concluded that RF could be the prediction technique of choice for an optimal sample comprised by both flares and CMEs, and the most important features for the identification of SEPs are the CME speed, width and flare soft X-ray (SXR) fluence.

Source of Energetic Protons in the 2014 September 1 Sustained Gamma-ray Emission Event
TL;DR: In this article, the authors report on the source of greater than 300 MeV protons during the SOL2014-09-01 sustained gamma-ray emission (SGRE) event based on multi-wavelength data from a wide array of space and ground-based instruments.
Journal ArticleDOI
Interplanetary Type IV Bursts
TL;DR: In this article, the authors studied the characteristics of moving type IV radio bursts that extend to hectometric wavelengths (interplanetary type IV or type $\text{IV}_{\text{IP}}$cffff ǫbursts) and their relationship with energetic phenomena on the Sun.
