Generative Simulations of The Solar Corona Evolution With Denoising Diffusion : Proof of Concept
Grégoire Francisco, Francesco Pio Ramunno, Manolis K. Georgoulis +3
The solar magnetized corona is responsible for various manifestations with a space weather impact, such as flares, coronal mass ejections (CMEs) and, naturally, the solar wind. Mod…
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…
Assessment of the near-Sun magnetic field of the 10 March 2022 coronal mass ejection observed by Solar Orbiter
Shifana Koya, Spiros Patsourakos, Manolis K. Georgoulis +1
We estimate the near-Sun axial magnetic field of a coronal mass ejection (CME) on 10 March 2022. Solar Orbiter's in situ measurements, 7.8 degrees east of the Sun-Earth line at 0.4…
Magnetogram-to-Magnetogram: Generative Forecasting of Solar Evolution
Francesco Pio Ramunno, Hyun-Jin Jeong, Stefan Hackstein +3
Investigating the solar magnetic field is crucial to understand the physical processes in the solar interior as well as their effects on the interplanetary environment. We introduc…
Magnetic Helicity Signs and Flaring Propensity: Comparing Force-free Parameter with the Helicity signs of Hα Filaments and X-ray Sigmoids
V. Aparna, Manolis K. Georgoulis, Petrus C. Martens
Sigmoids produce strong eruptive events. Earlier studies have shown that the ICME axial magnetic field Bz can be predicted with some credibility by observing the corresponding fila…
Explainable Deep Learning-based Solar Flare Prediction with post hoc Attention for Operational Forecasting
Chetraj Pandey, Rafal A. Angryk, Manolis K. Georgoulis +1
This paper presents a post hoc analysis of a deep learning-based full-disk solar flare prediction model. We used hourly full-disk line-of-sight magnetogram images and selected bina…
