Triple coronal Hard X-ray source observed by STIX during a failed filament eruption

We investigate the SOL2022-02-15T1815 solar flare, accompanied by a failed eruption, finding an answer to the question: What is the nature of coronal HXR sources accompanying the event? The HXR emission sources related to the interaction between the eruption and the overlying magnetic field might be typical structures observed in all flares. However, they seem to be weak as their emission is at the level of 5-20% of the flare coronal source.The deposited data is used to prepare an article: Mrozek, T. et al. 2025, Triple coronal Hard X-ray source observed by STIX during a failed filament eruption, Astronomy & Astrophysics, in press.
