Tonight in Värmland
36%

Worth watching through the dark half of the year
Kp 5 is a moderate storm — not an everyday event, but common enough that a patient observer in Värmland sees the aurora borealis most winters.

Solar declination and hour angle at −18°
Nothing to see from May to August
Through those months the sun never falls more than 18° below the Värmland horizon, so the sky never darkens fully. Plan around the darker half of the year.
Getting clear of the light
The sky over Värmland reads Bortle 5. 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, September, March and October came out ahead in Värmland. 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 Värmland viewing season.

Common questions about the aurora borealis in Värmland
Can you see the aurora borealis from Värmland?
Yes. On the last 10.0 years of NOAA Kp records, Värmland had about 21.3 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 Värmland?
Kp 5. Värmland sits at geomagnetic latitude 58.6°, and the auroral oval only reaches that far from the pole once activity hits Kp 5. Storms that size occur about 28.7 nights a year.
When is the best time of year to see the aurora borealis in Värmland?
September, March and October. Those months scored highest once both conditions are counted together: geomagnetic activity and enough hours of real darkness. From May to August the sky over Värmland never gets fully dark, so nothing is visible however strong the storm.
Where can you escape the light pollution near Värmland?
The centre of Värmland reads Bortle 5. The nearest sky at Bortle 4 is about 18 km north around Karlstads kommun. On a marginal night that drive matters more than the forecast does.
Where is the nearest place to Värmland with reliable aurora borealis?
Bodø, Norway — 883 km north. It needs only Kp 3 and averages 171.4 viable nights a year against 21.3 in Värmland.
