What is Kp?

  • Kp is a 0–9 scale for how disturbed the Earth's magnetic field is. The higher the Kp, the further south the aurora reaches.
  • Here in Örnsköldsvik you normally need about Kp 3 for the aurora to reach the sky.
  • Clouds beat everything: with an overcast sky even a strong storm stays invisible.
