SOLER

The SOLER project will investigate energetic solar eruptions starting from three perspectives: fast coronal mass ejections (CMEs), strong X-ray flares, and large solar energetic particle (SEP) events. Key parameters of the eruptions will be determined and their interrelations examined to improve our understanding on how the eruptive phenomena are linked, how they interact with each other, and how they result in acceleration of high energy particles and their release from the solar corona into interplanetary space. Large-amplitude coronal waves and shocks related to these events as well as magnetic connections of the radiation sources with the in-situ observers will be in focus as well. SOLER will answer three science questions: – What are the magnetic connections between EM radiation sources in the low corona and in the high corona and how are they connected to the particle radiation observed in situ? – What is the relation of the properties of the in-situ SEP observations with the source characteristics and between the source characteristics themselves? – What are the reasons for the large variations in SEP properties and associated flare and CME characteristics? Related to these scientific questions, SOLER has also technical objectives. SOLER will: – deliver interlinked catalogues of strong flares, fast CMEs and large SEP events. – deliver new tools for analysing and visualising solar eruption datasets and modelling results and distribute them openly to the scientific community. – produce several high-level multi-instrument datasets and distribute them openly to the scientific community. SOLER will use ESA, NASA and national mission data along with ground-based observations, and a variety of innovative data and image processing techniques together with cutting-edge models. SOLER analysis activities will directly lead to dozens of scientific publications. Catalogues, datasets and tools will be openly available for the community for further exploitation of data.
