The sun is now being asked for its schedule
the sun is now being asked for its schedule: nasa’s coffies model predicts storm-causing active regions up to 12 hours before they emerge, a multi-task network forecasts flares and coronal mass ejections together, and sheffield models reading 30 years of helioseismic data put solar cycle 25’s minimum around 2030 to 2031.
the star now issues its own weather alerts.
Context
NASA said on Aug 14 that its COFFIES team developed a sliding-window Transformer to forecast solar active regions, and an NJIT-led team reports an AI system that spots faint warning signals of active regions hours before they emerge. A Sheffield team ran 30 years of GONG helioseismic data through three machine learning models and all three predict Solar Cycle 25 bottoming out (Startgaze, May 21).
Separate papers cover multi-task deep learning for solar energetic particles and flare to CME associations.
COFFIES active region forecasting, the Sheffield helioseismic forecast and multi-task solar models match the sources. The '12 hours' lead time and the 'around 2030 to 2031' minimum were not seen as exact figures in the excerpts read, so they are unsupported here, not refuted. NJIT says 'hours' before emergence.
'The star now issues its own weather alerts' is the author's opinion.

the current is now being asked to draw its own map: china’s langya 2.0 predicts six ocean phenomena including internal waves and mesoscale eddies, a deep net called wenhai resolves eddies globally with air sea flux formulas built in, and scripps infers surface currents from the way temperature patterns deform in satellite images. the ocean now files its own circulation report.

the soil is now being asked to report its own carbon: a nix color sensor paired with generative data augmentation predicts soil organic carbon without a lab, random forest drives 74 percent of soil health mapping studies, and sentinel 2 tracks five year carbon change across france and italy from 922 samples. the dirt now files its own carbon account.
