AI model MAGiDiff estimates solar magnetic fields from UV/EUV filtergrams

By PulseAugur Editorial · [1 sources] ·

Researchers have developed MAGiDiff, a novel machine-learning method utilizing denoising diffusion models to estimate photospheric vector magnetic fields from UV/EUV filtergrams. This approach aims to overcome the challenges of direct measurement, which typically requires complex Stokes vector inversion. MAGiDiff takes filtergrams from the Solar Dynamics Observatory (SDO) / Atmospheric Imaging Assembly (AIA) as input and is trained to output vector magnetograms comparable to those from the Hinode / Solar Optical Telescope-Spectro-Polarimeter (SOT-SP). The model demonstrates accuracy in mimicking ground-truth data and shows generalization across solar cycles and adaptability to other EUV instruments. AI

IMPACT This AI-driven approach could enhance solar activity modeling and forecasting by providing more accessible vector magnetogram data.

    MAGiDiff: Sampling the Photospheric Vector Field from UV/EUV Filtergrams

    arXiv:2609.40043v1 Announce Type: cross Abstract: Photospheric vector magnetic fields are foundational to modeling, understanding, and forecasting solar activity. These data are usually produced by inverting and disambiguating the full Stokes vector at multiple passbands, which i…
