Table showing different categories of geomagnetic storm and associated K p levels. The categorization is done based on the intensity of the geomagnetic storm following the NOAA SWPC scales.
|Storm level||K p range|
|G0||K p < 5−|
|G1||5− ≤ K p < 6−|
|G2||6− ≤ K p < 7−|
|G3||7− ≤ K p < 8−|
|G4||8− ≤ K p < 9−|
|G5||K p > 9−|
