Kp-Index (Disturbance)
Measures geomagnetic activity on a scale of 0 to 9. Higher values indicate Earth's magnetic field is being shaken by the solar wind.

Wind Speed
The velocity of particles leaving the Sun. Fast winds (500+ km/s) act like a powerful blower that lights up the aurora.

IMF Bz (The Door)
Shows if the magnetic field is pointing South (negative). A negative Bz 'opens the door' for energy to enter our atmosphere.

Proton Density
The thickness of the solar wind. High density means more particles are hitting the atmosphere, making the aurora brighter.

HPI (Power GW)
Real-time estimate of the total energy (Gigawatts) entering the atmosphere. Higher GW = bigger, brighter aurora.

Radio Flux (F10.7)
Indicates how active the Sun is overall. During 'Solar Maximum', this number is high, meaning more solar storms.
