Active Sun

The purpose of WP1100 Active Sun is to better understand the link between solar magnetism and features in the layers of the solar atmosphere (photosphere, chromosphere, and corona) associated with the occurrence of the SWE drivers, i.e., what physical conditions on the Sun generate SWE events.

This WP will coordinate and monitor the activities aimed at characterising solar eruptions (in terms of magnetic field, flares and CMEs), study the evolution in the solar atmosphere of the main drivers of SWE phenomena, and assess the eruptive capability of solar active regions, which will be performed by the

WP1110 Photosphere

WP1120 Chromosphere

WP1130 Corona
