Tonight in Rouyn-Noranda

14%

Peak chance of a visible display tonight, from the same model the Revon app runs. Rouyn-Noranda 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 Rouyn-Noranda

Every night to come, scored the same way as tonight. The best of the open week is Sunday 2 Aug at 14%. Not one of the seven reaches the Kp 7 that Rouyn-Noranda 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.

Low activity for the next few days. Moderate aurora expected on August 19th.

Wait for an alert; do not book a week

At Kp 7, Rouyn-Noranda 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

Rouyn-Noranda is small enough that its own lights are a minor problem — the centre reads Bortle 4. Walking to the edge of town is often escape enough.

The months that actually deliver

Counting only nights that were both stormy enough and dark enough, May, September and August came out ahead in Rouyn-Noranda. 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 Rouyn-Noranda viewing season.

Where it is close to a certainty

If you would rather plan a trip than wait for a storm, the nearest place with genuinely frequent aurora is Nuuk, 2,412 km north-north-east in Greenland.

Where the horizon opens up near Rouyn-Noranda

The display sits low on the northern horizon, so what beats a better forecast is open ground facing that way. Height gets you above the town glow; water gives you an unbroken skyline. These are within a short drive of Rouyn-Noranda.

Common questions about the aurora borealis in Rouyn-Noranda

Can you see the aurora borealis from Rouyn-Noranda?

Yes. On the last 10.0 years of NOAA Kp records, Rouyn-Noranda 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 Rouyn-Noranda?

Kp 7. Rouyn-Noranda sits at geomagnetic latitude 57.5°, 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 Rouyn-Noranda?

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 Rouyn-Noranda?

The centre of Rouyn-Noranda reads Bortle 4. The nearest sky at Bortle 4 is about 2 km north-east. On a marginal night that drive matters more than the forecast does.

Where is the nearest place to Rouyn-Noranda with reliable aurora borealis?

Nuuk, Greenland — 2,412 km north-north-east. It needs only Kp 3 and averages 171.4 viable nights a year against 3.2 in Rouyn-Noranda.
