Northern lights tonight in Canada

Canada sits at about 69° magnetic latitude, so the aurora reaches it from roughly Kp 0.0 — most clear dark nights. The card below reads NOAA's oval, tonight's dark hours, the cloud and the Moon for Yellowknife, Northwest Territories right now.

Canada holds the oval's most favourable ground on the planet: because the magnetic pole sits over Canadian Arctic islands, Yellowknife at 62° north is 69° magnetic — deeper inside the oval than Tromsø — with a dry continental winter that gives it more clear aurora nights than anywhere in Norway. Churchill on Hudson Bay is under the oval too and is cloudier. Jasper is the southern dark-sky preserve at 60° magnetic, where a Kp 3 night shows an arc over the Athabasca valley and Kp 5 fills the sky. The Prairie provinces see aurora dozens of nights a year; the populated corridor from Toronto to Montréal needs a G2.
