An overview of works on potential distinct behaviors between flaring / eruptive and flare-quiet / non-eruptive solar active regions will be attempted. Focus will be assigned to the most distinctive physical quantities that characterize active regions, namely magnetic energy and helicity budgets, as well as associated non-neutralized electric currents. Emphasis will also be on the single most...
The formation of active nests/longitudes on the Sun may relate to instabilities at the base of the convective zone or the way in which magnetic flux emerges through the solar surface. Persistent hot spots of activity are frequently observed on other Sun-like stars, hinting that their formation may be universal for stars with dynamo-driven magnetic fields. Nested active region emergences...
Coronal mass ejections (CMEs) are the most energetic events originating from the Sun, causing significant and sudden disruption to the magnetic and particulate environment of the heliosphere. Thus, in the current era of space-based technologies, an early warning that a CME has left the Sun is crucial. Our magnetofrictional simulations that capture the global corona's continuous and dynamic...
The integration of medium-term and short-term solar flare predictions is a crucial component of space weather forecasting, given their potential impacts on Earth's technological infrastructure and astronaut safety. This presentation examines the importance of combining medium-term and short-term solar flare prediction methods to improve the reliability and precision of forecasts. Medium-term...
The Interplanetary Magnetic Field (IMF) plays a crucial role in shaping space weather and its impact on Earth's magnetosphere. However, the availability of direct IMF measurements is limited to recent decades, leaving a gap in our understanding of the Sun’s magnetic behavior over longer timescales. To address this, we present a detailed reconstruction of the IMF over the past century by...
Solar Flares release large amounts of energy in the form of radiations in multiple wavelengths. Predicting solar flares starting time and their class is a difficult task. When and at what solar atmospheric layer the flare trigger happens, whether in the corona, transition region or in the chromosphere, is still a puzzle. One way forward is to study the pre-flare signatures in multi-wavelengths...
