Why these months?
Two things decide your odds in Kilpisjärvi: darkness and activity. You need real darkness — so the bright midnight-sun months are out no matter how strong the aurora is. On top of that, geomagnetic storms run statistically stronger around the spring and autumn equinoxes (the Russell–McPherron effect), which is why September and October and February and March tend to edge out the dead of winter. Kilpisjärvi's season runs late september to early april.
Kilpisjärvi is the village at the far end of Finland's northwestern arm, wedged between Sweden and Norway under the fell Saana. It is Finland's highest and most northerly settlement and sits well under the oval.
Where to stand in Kilpisjärvi
