Aurora Forecast — Edmonton
Edmonton is a sub-auroral location — it catches the aurora low on the northern horizon during minor-to-moderate geomagnetic storms (Kp 5 and up).
Unlikely tonight
The aurora is unlikely from Edmonton right now: the Kp is 1.0, below the Kp 3+ this location needs for the oval to reach you. Worth checking back if a geomagnetic storm is forecast — that's when the lights push this far south.
Sources: Kp from NOAA SWPC · cloud from Open-Meteo · Moon & darkness computed · viewing threshold from Edmonton's geomagnetic latitude (IGRF). Figures update through the night.
How tonight's verdict is worked out for Edmonton
Most aurora trackers show you a single number — the Kp index — and leave the rest to you. Seeing the aurora actually depends on five things, and we weigh all of them for Edmonton:
- Where Edmonton sits — its geomagnetic latitude is about 61°, which sets the Kp it needs (roughly Kp 3).
- How active the field is — the live Kp index, right now 1.0.
- Cloud cover — thick cloud hides the lights completely; this is usually the factor that decides the night.
- Darkness — the aurora is invisible in twilight, and in far-northern midsummer the sky may never get truly dark.
- The Moon — a bright Moon washes out a faint display (a strong one still shows through).
Only when the activity reaches the level Edmonton needs andthe sky is clear and dark do we call it “likely.” If something's holding the night back, the verdict says which.
Seeing the northern lights from Edmonton
On a promising night, get away from street lighting, give your eyes 20 minutes to adapt, and look toward the northern horizon. A faint grey-green arch to the naked eye often shows up far more vividly through a phone or camera on a long exposure.
