Solar Physics index
Local map for the solar-physics notes in this vault.
Current focus
This folder currently leans toward coronal magnetic-field modelling: HMI/SHARP vector magnetograms, NLFFF assumptions, NF2/PINN extrapolation, and the AR11158 reproduction project. General solar-physics notes can grow around this, but the useful centre of gravity right now is “how do we get a credible 3D coronal magnetic field from surface data?”
