Plan­ning your aurora chase

1 Check the KP in­dex

Ge­o­mag­netic ac­tiv­ity can be pre­dicted – to an ex­tent – by check­ing the KP in­dex on a site such as www.spaceweath­er­live.com. The KP in­dex de­fines aurora ac­tiv­ity on a scale of 0 to 9, with any­thing above KP5 be­ing clas­si­fied as a ge­o­mag­netic storm. Un­less it’s at KP2 or more you’re un­likely to see any­thing.

2 Watch the weather

The skies need to be at least par­tially cloud-free. If there’s blan­ket cloud, rain or snow then there’s lit­tle chance of see­ing any­thing. So check the lo­cal cloud maps. It’s more likely you’ll see it in the north­ern por­tion of the sky, often as a band along the horizon. So scout out a clear, in­ter­est­ing view in that di­rec­tion.
