Triple coronal Hard X-ray source observed by STIX during a failed filament eruption
No full textWe 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.</p

No full textThis data set contains results of automated search in SDO/AIA data base. We performed the search in Lev1.5 data obtained with 171 Å filter. The automated algorithm (Mrozek et al. 2016) was constructed for searching of mass movement in the solar atmosphere. Therefore, we have found a variety of moving strucutres: small jets, mass motions inside closed loops, jets, oscillating loops, full and partial eruptions, a group of failed eruptions, and plasma draining after eruption. We collected here files (IDL sav format) for all found events in one zipped file. Details of files are described on the catalog page: www.eruptivesun.com</p

Detection of the third innermost radiation belt on LEO CORONAS-Photon satellite around 2009 solar minimum
No full textWe analyze variations of high energy charged particle populations filling various magnetospheric regions under, inside and outside of the Van Allen inner and outer electron radiation belts in May 2009. The study is based on the experimental data obtained from the STEP-F and the SphinX instruments placed close to each other aboard the low-Earth circular orbit CORONAS–Photon satellite. Data analysis of particle fluencies collected from the highly sensitive STEP-F device indicates the presence of a persistent electron belt at L ≈ 1.6, i.e., beneath the well-known Van Allen electron inner radiation belt of the Earth’s magnetosphere. Cross-analyses of data obtained from the STEP-F and SphinX instruments initially built for various purposes made it possible to detect the highly anisotropic character of the spatial electron distribution in radiation belts in both Southern and Northern hemispheres. We detected also the presence of low-energy electrons at all latitudes during the main phase of a weak geomagnetic storm.</p
Solar flares with the most distinct pulses April 2020 - March 2022: STIX QPPs flare list
No full textThis work aimed to conduct a statistical study of the periods and amplitudes of QPPs observed in quick-look light curves of the STIX instrument. The quick-look light curves recorded from April 14, 2020 (the beginning of the mission) to the end of March, 2022 were scrutinised. 129 flares with the most distinct pulses were selected, for which the periodicity analysis was carried out using the Lomb-Scargle periodogram and the autocorrelation method. This sample contained mostly weak B- and C-class flares. It was found that 70% of examined flares showed statistically significant oscillations. Longer periods occur less frequently than shorter ones. We also identified a relationship between the period and the duration in which the oscillations were observed.This dataset cotains two version of the list: zipped .xlsx version with formatted footnotes and RepOD-analysed version available for download in .tab, .rdata and .xlsx formats.</p
