Solar Orbiter Major Flare Campaigns and EUI/HRI studies

Talk

Solar Orbiter major flare campaigns provide, for the first time, high-resolution unsaturated EUV imaging (EUI) together with X-ray spectroscopic imaging (STIX). Fine structures in flare ribbons are observed on previously inaccessible scales (0.1Mm on 2s cadence), and provide an opportunity to test the standard idea of non-thermal electron beams driving energy transport in flares. We performed...

Solar Orbiter Major Flare Campaigns and EUI/HRI studies

Talk

Solar flare simulations are often driven by electron beam parameters inferred from X-ray observations. One important input is the electron beam flux, which depends on both the non-thermal power and the assumed flare footpoint area. In this work, we compare footpoint areas estimated from STIX X-ray imaging with those measured from higher-resolution EUI observations for a Solar Orbiter flare....

Solar Orbiter Major Flare Campaigns and EUI/HRI studies

Talk

After more than two years of chasing solar flares with the EUI/HRI, we have established a catalogue of about 50 solar flares with 174A images at a few second time cadence. Single event studies have shown that there is a very close temporal link between the EUV and HXR flux from flare ribbons during the impulsive phase. This correlation holds for all of the 10 M-class flares revealing a linear...
