Table 1
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− |
