Efficiency of solar microflares in accelerating electrons when rooted in a sunspot
Jonas Saqri, Astrid M. Veronig, Andrea Francesco Battaglia +3
We investigate two microflares of GOES classes A9 and C1 (after background subtraction) observed by STIX onboard Solar Orbiter with exceptionally strong nonthermal emission. We com…
The existence of hot X-ray onsets in solar flares
Andrea Francesco Battaglia, Hugh Hudson, Alexander Warmuth +9
It is well known among the scientific community that solar flare activity often begins well before the main impulsive energy release. Our aim is to investigate the earliest phase o…
Multi-point study of the energy release and transport in the 28 March 2022, M4-flare using STIX, EUI, and AIA during the first Solar Orbiter nominal mission perihelion
Stefan Purkhart, Astrid M. Veronig, Ewan C. M. Dickson +6
We present a case study of an M4-class flare on 28 March 2022, near Solar Orbiter's first science perihelion (0.33 AU). Solar Orbiter was 83.5° west of the Sun-Earth line, making t…
On the three-dimensional relation between the coronal dimming, erupting filament and CME. Case study of the 28 October 2021 X1.0 event
Galina Chikunova, Tatiana Podladchikova, Karin Dissauer +4
We investigate the relation between the spatiotemporal evolution of the dimming region and the dominant direction of the filament eruption and CME propagation for the 28 October 20…
Initial radiometric calibration of the High-Resolution EUV Imager () of the Extreme Ultraviolet Imager (EUI) instrument onboard Solar Orbiter
S. Gissot, F. Auchère, D. Berghmans +21
The telescope was calibrated on ground at the Physikalisch-Technische Bundesanstalt (PTB), Germany's national metrology institute, using the Metrology L…
Magnetic Energy Powers the Corona: How We Can Understand its 3D Storage & Release
Amir Caspi, Daniel B. Seaton, Roberto Casini +12
The coronal magnetic field is the prime driver behind many as-yet unsolved mysteries: solar eruptions, coronal heating, and the solar wind, to name a few. It is, however, still poo…
