What Geomagnetic Storm Forecast gives you.
Today's storm level
The current planetary activity level on a 0 to 9 scale, refreshed as each new 3-hour value arrives.
A 3-day geomagnetic storm forecast
Predicted activity for the next three days in 3-hour steps, alongside recent observed values, plus the written outlook for radio blackouts and radiation storms.
The geomagnetic storm scale, in plain words
Storms run from G1 to G5. Kp 5 is a minor storm (G1), Kp 6 moderate (G2), Kp 7 strong (G3), Kp 8 severe (G4) and Kp 9 extreme (G5). Higher levels push the aurora further from the poles and can disturb positioning, radio and power grids.
