Méthode et sources

Les séries temps réel (vent solaire RTSW à la minute, flux X et protons GOES, Kp) sont importées toutes les dix minutes à une heure depuis les services JSON de la NOAA SWPC et s’accumulent au fil des imports ; elles sont signalées comme provisoires. Les probabilités, la prévision géomagnétique, les régions actives, les éruptions et les alertes sont conservées dans leur dernière version publiée.

Lire ces données
Données temps réel non validées : les valeurs définitives (OMNI, catalogues GOES) arrivent plus tard et peuvent différer. Les probabilités sont des prévisions de la NOAA, pas des calculs de ce site.
