Wait for an alert; do not book a week

At Kp 7, Edmundston 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

Edmundston 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 Edmundston. 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 Edmundston 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, 2,123 km north-north-east in Greenland.

Where the horizon opens up near Edmundston

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 Edmundston.

What to do with the daylight

Aurora watching is a night job, and in winter that leaves a short, bright day to fill. Close to Edmundston you will find WSJR-AM (Madawaska) and WCXX-FM (Madawaska), and for a day when the cloud sits low, Tante Blanche Museum are indoors and near by.

Keep the daylight loose: the sky decides the evening, and the forecast can turn within a few hours.

Where to stay

Anywhere on the outskirts of Edmundston will do; what matters is being able to step outside and check the sky without a drive first.

Common questions about the aurora borealis in Edmundston

Can you see the aurora borealis from Edmundston?

Yes. On the last 10.0 years of NOAA Kp records, Edmundston 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 Edmundston?

Kp 7. Edmundston sits at geomagnetic latitude 56.7°, 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 Edmundston?

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 Edmundston?

The centre of Edmundston reads Bortle 4. The nearest sky at Bortle 2 is about 15 km north-north-east around Saint-Joseph Parish. On a marginal night that drive matters more than the forecast does.

Where is the nearest place to Edmundston with reliable aurora borealis?

Nuuk, Greenland — 2,123 km north-north-east. It needs only Kp 3 and averages 171.4 viable nights a year against 3.2 in Edmundston.
