Is Bodø or Kiruna better for the northern lights?

Bodø sits closer to the oval, at 66.0 degrees geomagnetic against 65.7. Darkness, cloud and your dates decide the rest; the tables on this page show both towns month by month.

Which has longer nights in December, Bodø or Kiruna?

Kiruna, with 18.3 hours of civil night on December 15 against 18.0 in Bodø.

What Kp do Bodø and Kiruna need?

By SWPC's rule of 66 degrees at Kp 0 and 2 degrees per step, Bodø needs about Kp 0 and Kiruna Kp 1 for the average oval edge to sit overhead.

When is it too light for aurora in Bodø and Kiruna?

Bodø: May 5 to August 6. Kiruna: May 3 to August 8.

Which is clearer, Bodø or Kiruna?

Kiruna, with 75% mean cloud in the months with 4 hours or more of civil night against 82% in Bodø (NASA POWER, 2001 to 2020).

Comparison

Bodø vs Kiruna for the northern lights

Answer

Bodø sits 0.3 degrees higher on the IGRF-14 dipole, 66.0 against 65.7. By SWPC's oval-edge rule Bodø needs about Kp 0 for the average edge to sit overhead and Kiruna Kp 1. That reverses the map, where Kiruna is 0.6 degrees closer to the pole.

Bodø sits at 66.0 degrees geomagnetic, inside SWPC's 60 to 75 degree band, where aurora can be seen on more than half of all nights. No storm is needed: by SWPC's rule the average oval edge is overhead at Kp 0. Kiruna sits at 65.7 degrees geomagnetic, inside SWPC's 60 to 75 degree band, where aurora can be seen on more than half of all nights. No storm is needed: by SWPC's rule the average oval edge is overhead at Kp 1.
