Archief van geomagnetische stormen sinds 1932
De Kp-index wordt sinds 1932 onafgebroken gemeten en is daarmee een van de langste meetreeksen in de ruimtewetenschap. Dit archief toont per jaar hoeveel dagen stormniveau haalden (Kp 5 en hoger), hoeveel er sterk of extreem waren en welke dagen het hevigst waren.
De elfjarige zonnecyclus is duidelijk te zien: stormdagen clusteren rond het zonnemaximum en nemen af naar het minimum.
