swr01 The solar sources of space weather

Conveners: Astrid M. Veronig (Institute of Physics & Kanzelhöhe Observatory, University of Graz), Karin Dissauer (NorthWest Research Associates (NWRA), Boulder, Colorado, USA) and Tatiana Podladchikova (Space Center, Skolkovo Institute of Science and Technology (Skoltech)

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, medium-­-sized storms can also arise from high-­-speed streams emanating from coronal holes.

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.
