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.
  • Northern Sweden needs roughly Kp 1–2, central Sweden Kp 4 and southern Sweden Kp 6–7.
  • Clouds beat everything: with an overcast sky even a strong storm stays invisible.
