Kp 8 is a step up from Kp 7 and below Kp 9.
What Kp 8 means tonight
Kp 8 is a G4 severe geomagnetic storm - rare and spectacular. At this level aurora has been photographed from Spain, Italy, the south of France, Texas, Florida, and parts of the southern hemisphere. G4 storms occur only a few times per solar cycle. When one arrives, the entire night sky at mid-latitudes can display aurora. The G4 event of May 2024 produced some of the most widely photographed aurora displays in decades.
