Geomagnetic Activity
Kp 5 or higher means geomagnetic storm conditions. This can increase aurora visibility while adding operational risk for satellites and radio systems.

Magnetic Coupling
Southward Bz allows solar wind energy to couple more efficiently into Earth magnetic field, raising storm and aurora potential.
Solar Wind Pressure
Higher solar wind speed and density can compress the magnetosphere and make geomagnetic changes more likely.
