Solar flares and CMEs are some of the most energetic phenomena in the heliosphere, with the potential to cause significant disruption of technological infrastructure on Earth. Transient events range from large-scale structures such as CMEs to small-scale highly dynamic phenomena (e.g., spicules, jets, waves, Ellerman bombs), which are important for understanding the dynamics of the Sun's atmosphere, including its heating, and the processes that drive its activity.
This splinter meeting will bring together researchers from all areas of solar physics and heliophysics to discuss the latest observations and models of transient events at all scales.
The aim is to advance our understanding of solar flares, CMEs, and other transient events combining a variety of data sources including ground-based and space-based observatories, as well as numerical simulations. Topics to be covered in this splinter include the physical mechanisms that trigger these events, their evolution on different spatial and temporal scales, and the techniques used to observe and model these phenomena. The field is constantly evolving making it a fascinating and exciting area of research. We are welcoming contributions in the form of talks and posters from both observers and theorists, and encourage in particular early career scientists to apply.
