When can you photograph the aurora at Yellowknife?

Because the magnetic pole leans toward Canada, Yellowknife sits at geomagnetic ~67° despite a modest geographic latitude — one of the most reliable aurora locations on Earth.

What decides a good night here

• Kp 0–1 is enough here; the flat sub-Arctic terrain gives unobstructed horizons in every direction.
• A dry continental climate means frequent clear nights across the late-August-to-mid-April season.
• The lakes freeze early and make mirror-flat reflective foregrounds under the arc.

Honest note: This is the North-American proof that geographic latitude misleads — Yellowknife beats places much further north on the map because geomagnetic latitude is what counts.

ShootWindow computes all of this hour by hour for Yellowknife's exact coordinates — geomagnetic latitude, the NOAA Kp forecast, darkness and cloud — and turns it into concrete windows instead of a raw forecast.
