Tonight in Aurora
1%
Peak chance of a visible display tonight, from the same model the Revon app runs. Aurora needs Kp 7 to see anything at all, and tonight the forecast peaks at Kp 5.1. Short of the threshold, which is what most nights look like here.

The next 30 nights in Aurora
Every night to come, scored the same way as tonight. The best of the open week is Sunday 2 Aug at 1%. Not one of the seven reaches the Kp 7 that Aurora needs, which is normal rather than unlucky — it averages 3.2 viable nights a year. The 23 nights past the seven-day window move with the 27-day solar rotation and are updated daily in the app.

Wait for an alert; do not book a week
At Kp 7, Aurora needs a severe geomagnetic storm before anything shows above the northern horizon. Storms that size arrive a handful of times per solar cycle and announce themselves a day or two ahead. Watching for one beats picking dates and hoping.

Getting clear of the light
The sky over Aurora reads Bortle 7. Getting clear of the built-up area makes a visible difference on a marginal night.

The months that actually deliver
Counting only nights that were both stormy enough and dark enough, May, September and August came out ahead in Aurora. That is storm season and darkness overlapping — the equinoxes tend to be geomagnetically active, and the nights are already long by then.
Darkest nights of the coming year
A bright moon washes out a weak display as effectively as street lighting. These new moons fall inside the Aurora viewing season.

Common questions about the aurora borealis in Aurora
Can you see the aurora borealis from Aurora?
Yes. On the last 10.0 years of NOAA Kp records, Aurora had about 3.2 nights a year when the storm was strong enough and the sky dark enough at the same time.
What Kp index do you need to see the aurora borealis in Aurora?
Kp 7. Aurora sits at geomagnetic latitude 53.3°, and the auroral oval only reaches that far from the pole once activity hits Kp 7. Storms that size occur about 3.2 nights a year.
When is the best time of year to see the aurora borealis in Aurora?
May, September and August. Those months scored highest once both conditions are counted together: geomagnetic activity and enough hours of real darkness.
Where can you escape the light pollution near Aurora?
The centre of Aurora reads Bortle 7. The nearest sky at Bortle 4 is about 58 km north-north-east around Ramara Township. On a marginal night that drive matters more than the forecast does.
Where is the nearest place to Aurora with reliable aurora borealis?
Nuuk, Greenland — 2,836 km north-north-east. It needs only Kp 3 and averages 171.4 viable nights a year against 3.2 in Aurora.
