Improved modelling of SEP event onset within the WSA-Enlil-SEPMOD framework
Richardson, Ian G.; Auster, Hans-Ulrich; Palmerio, Erika +14 more
Multi-spacecraft observations of solar energetic particle (SEP) events not only enable a deeper understanding and development of particle acceleration and transport theories but also provide important constraints for model validation efforts. However, because of computational limitations, a given physics-based SEP model is usually best suited to c…
A catalogue of observed geo-effective CME/ICME characteristics
Foldes, Raffaello; Erdélyi, Robertus; Del Moro, Dario +7 more
One of the goals of Space Weather studies is to achieve a better understanding of impulsive phenomena, such as Coronal Mass Ejections (CMEs), to improve our ability to forecast their propagation characteristics and mitigate the risks to our technologically driven society. The essential part of achieving this goal is to assess the performance of fo…
Multi-instrument observations and tracking of a coronal mass ejection front from low to middle corona
Stepanyuk, Oleg; Kozarev, Kamen
The shape and dynamics of coronal mass ejections (CMEs) vary significantly based on the instrument and wavelength used. This has led to significant debate about the proper definitions of CME/shock fronts, pile-up/compression regions, and core observations in projection in optically thin vs. optically thick emission. Here we present an observationa…
