NOAA Geomagnetic Storm Scales

NOAA Scales Geomagnetic Storms

The G-scale used by the US National Oceanic and Atmospheric Administration rates the storm from G1 to G5, ie G1, G2, G3, G4, G5, in order, where G1 is the weakest and G5 is the strongest.

NOAA Scales Geomagnetic Storms

The scales describe the environmental disturbances for three event types: Geomagnetic storms, solar radiation storms, and radio blackouts.

NOAA Scales Geomagnetic Storms

A geomagnetic storm is a major disturbance of Earth's magnetosphere that occurs when there is a very efficient exchange of energy from the solar wind to the magnetosphere.

Kp 5: G1

Kp 6: G2

Kp 7: G3

Kp 8, 9-: G4

Kp 9o: G5

Conclusion

As a result, forecasters currently anticipate G1-Minor geomagnetic storm levels over these three days, with higher storm levels possible if more of the Coronal Mass Ejections hit Earth's magnetic field.
