Where the towns sit

60° geomagnetic or more, no storm needed55° to 60°, G1 or lessbelow 55°, storm needed

The widest gap in the dipole ranking falls between Århus and Horsens, 0.2 degrees. 7 neighbouring pairs sit within 0.5 degrees of each other, close enough that the order between them means little.

Of the 8 indexed towns in Central Jutland, 8 sit between 55 and 60 degrees, where G1 (Kp 5) or less usually brings aurora into view.
