Session SWR1 - Solar Sources of Space Weather

Judith de Patoul, onsite (Royal Observatory of Belgium, Belgium), Hebe Cremades (Uni. Mendoza and CONICET, Argentina), Barbara Perri, onsite (KU Leuven, Belgium)

The Sun is our superstar, shaping the near-Earth space environment and driving our (space) climate and space weather. Flares, Coronal Mass Ejections (CMEs), associated shock waves and Solar Energetic Particles (SEPs) are the main sources of major space weather disturbances at Earth and other planets. The strongest events originate from large, magnetically complex active regions. In addition, stealth CMEs and high-speed streams emanating from coronal holes can also unleash medium-sized storms.
In this session, we invite contributions on all topics relating to the build-up, origin, triggering and early dynamics of solar eruptive events, that provide us with a better characterization, diagnostics and deeper physical understanding of the solar sources of space weather events, which is key to improve space weather predictions. This covers both observational and modelling approaches, as well as new techniques and studies on the conditions for extreme events.
