High-resolution Fe I and Mg I spectral observations reveal that solar flare ribbons are modulated by stable uncombed chromospheric loops and non-flaring fine structures.
A coupled nested-grid MHD framework with AMR to 700 km resolution and Boris correction for strong fields enables end-to-end simulation of CME emergence, eruption, and heliospheric propagation from realistic active-region scales.
Hybrid neural network predicts eruptive versus confined solar flares from SDO/HMI magnetogram sequences, reports good performance, and links results to magnetic flux cancellation in polarity inversion lines.
Confined flares exhibit total Lorentz force change below 1.8 × 10^22 dyne along the PIL, separating them from eruptive flares in a sample of 37 major events observed 2011-2017.
Observational data-driven MHD simulations reproduced an X1.6 flare's onset and showed that photospheric velocity input extends prediction lead time beyond one hour.
Persistent same-polarity flux emergences drove collisional shearing and cancellations at a PIL, accumulating free energy and forming MFRs that produced multiple large flares including X9.0, with a pre-flare drop in photospheric free-energy area as a possible precursor.
Pre-flare IRIS observations of an X9 flare reveal 7-21 minute oscillations and rising Si IV velocities consistent with slow coronal magnetic destabilization before rapid reconnection.
