Pourquoi la latitude ordinaire vous trompe

L'aurore forme un anneau autour du pôle nord magnétique, pas du pôle géographique. Ils sont distants de centaines de kilomètres : le pôle magnétique se trouve au-dessus du nord du Canada.

L'anneau est donc décentré. Il descend plus bas sur l'Amérique du Nord et l'Europe, et remonte au-dessus de la Sibérie. Deux villes à égale distance de l'équateur peuvent donc avoir des chances très différentes.

Édimbourg a besoin d'une tempête modérée — il en arrive plusieurs par an. Moscou a besoin d'une des plus fortes jamais enregistrées. La différence : Édimbourg est plus près du pôle magnétique.

L'inverse est vrai aussi. Yellowknife est à 62,5° sur une carte mais à 67,2° géomagnétiquement, d'où un besoin de tempête quasi nul et l'un des meilleurs spots au monde.

Comment lire le tableau

Plus la latitude géomagnétique est haute, moins la tempête doit être forte. Au-dessus d'environ 65°, l'aurore apparaît la plupart des nuits claires et sombres. Sous 50° environ, il faut un événement exceptionnel.

La dernière colonne donne le Kp minimal — l'échelle 0–9 des tempêtes géomagnétiques — à partir duquel l'ovale auroral atteint la ville. Il faut encore qu'il fasse nuit et que le ciel soit dégagé.

La latitude géomagnétique est calculée à partir des coordonnées de chaque ville par rapport au dipôle géomagnétique. Les villes de l'hémisphère sud sont en valeur absolue — l'aurore australe se comporte de façon identique, en miroir.
