Understanding the Origins of Problem Geomagnetic Storms Associated with "Stealth" Coronal Mass Ejections
Rouillard, Alexis P.; Pagano, Paolo; Nitta, Nariaki V. +14 more
Geomagnetic storms are an important aspect of space weather and can result in significant impacts on space- and ground-based assets. The majority of strong storms are associated with the passage of interplanetary coronal mass ejections (ICMEs) in the near-Earth environment. In many cases, these ICMEs can be traced back unambiguously to a specific …
Linking the Sun to the Heliosphere Using Composition Data and Modelling
Del Zanna, Giulio; Wimmer-Schweingruber, Robert F.; Lynch, Benjamin J. +13 more
Our understanding of the formation and evolution of the corona and the heliosphere is linked to our capability of properly interpret the data from remote sensing and in-situ observations. In this respect, being able to correctly connect in-situ observations with their source regions on the Sun is the key for solving this problem. In this work we a…
