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
