Northern Lights in Whitehorse Tonight
Live geomagnetic activity, the level Whitehorse actually needs, and tonight's cloud — one verdict instead of three tabs.
Whitehorse the current Kp is at or above what this latitude needs, so aurora may be visible if the sky is dark and clear.
Kp from NOAA SWPC. Cloud forecast from MET Norway (CC BY 4.0). Geomagnetic latitude ≈64° via a dipole approximation, good to a degree or two.
Next 3 days
NOAA predicted Kp in 3-hour blocks (UTC). Peaks at Kp 3.7 — reaches Whitehorse's threshold.
How to actually see it from Whitehorse
Three things have to line up: activity (the Kp above), darkness and a clear northern horizon. Get away from city lights, look north, and give your eyes twenty minutes. Cameras pick up colour long before eyes do — a grey shimmer on the horizon often photographs green.
Kp is a global index updated every few minutes, and substorms can spike activity with little warning — if the forecast shows a peak, it is worth checking the sky either side of it, not just at the listed hour.
