Brightenings AnD Polarity Inversion Tracking (BADPIT) method for studying solar active region evolution before major solar flares
Augustin André-Hoffmann, Marianna B. Korsós, Alexander Nindos +3
This study investigates the relationship between extreme ultraviolet (EUV) transient brightenings (TBs) and the onset of GOES X-class solar flares in active regions (ARs). We intro…
Chromospheric magnetic field extrapolations reveal the flux-rope configuration of a solar filament
Robert Jarolim, João M. da Silva Santos, Matthias Rempel +5
Solar eruptions are powered by the release of magnetic energy stored in the lower solar atmosphere, but the pre-eruptive magnetic configuration of filament channels remains difficu…
Case studies on pre-eruptive X-class flares using R-value in the lower solar atmosphere
Shreeyesh Biswal, Marianna B. Korsós, Manolis K. Georgoulis +3
The R-value is a measure of the strength of photospheric magnetic Polarity Inversion Lines (PILs) in Active Regions (ARs). This work investigates the possibility of a relation betw…
Improving the Automated Coronal Jet Identification with U-NET
Jiajia Liu, Chunyu Ji, Yimin Wang +5
Coronal jets are one of the most common eruptive activities in the solar atmosphere. They are related to rich physics processes, including but not limited to magnetic reconnection,…
