This ISSI team brings together an international group of researchers to study solar flares using unique observations from Solar Orbiter’s Extreme Ultraviolet Imager (EUI), in particular its High-Resolution Imager (HRI). These observations provide the first clear, high-speed views of solar flares without the saturation that affects many previous instruments, revealing fine detail in how flares evolve across the Sun’s atmosphere.
Our work focuses on analysing these EUI/HRI observations to track how flare ribbons and loops form and evolve, and to understand how energy is released and transported during a flare. By combining these data with simultaneous X-ray observations from the STIX instrument, we can link the heating of solar plasma to the acceleration of high-energy particles.
Alongside this, we are developing new data products, catalogues, and analysis tools to make these observations easier to use, and to guide future observing strategies for Solar Orbiter and next-generation solar missions.
