Parallel sessions

Coronal mass ejections (CMEs) are spectacular solar events, caused by eruptions of non-potential structures on the Sun which release vast quantities of plasma into the heliosphere. When Earth-directed, CMEs are the main drivers of hazardous space weather. As a society, we are becoming increasingly vulnerable to the impacts of a major CME. Tracking CMEs on their journey from onset to impact, and accurately forecasting CME properties has never been more relevant.

This session aims to study the entire chain, from the formation of the structure that erupts to CME propagation into the heliosphere, bringing together studies of remote sensing and in situ observations of CMEs. Such a connection science session is particularly timely with the launch of Solar Orbiter and Parker Solar Probe and the availability of different instruments which complement one another.

We invite contributions which explore observations of CMEs: from high-resolution on disk images of CME onset, to heliospheric imagery and in situ measurements in the inner heliosphere, to create a coherent picture of a CME’s journey. We particularly welcome contributions which combine different types of remote sensing observations with plasma parameters measured in situ.
