Tonight in Östergötland
36%

Wait for an alert; do not book a week
At Kp 7, Östergötland 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.

Nothing to see from May to August
Through those months the sun never falls more than 18° below the Östergötland horizon, so the sky never darkens fully. Plan around the darker half of the year.
Getting clear of the light
With 291,382 people around you, the sky over central Östergötland is Bortle 4. The glow hides anything but the brightest display, so the drive out matters more here than the forecast does.

The months that actually deliver
Counting only nights that were both stormy enough and dark enough, September, November and March came out ahead in Östergötland. 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 Östergötland viewing season.

Where the horizon opens up near Östergötland

What to do with the daylight
Aurora watching is a night job, and in winter that leaves a short, bright day to fill. Östergötland keeps its fortified past above ground, at Linköpings slott, and for a day when the cloud sits low, Östergötlands museum, Linköpings slotts- och domkyrkomuseum and Gamla Linköping Open-Air 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
Staying central in Östergötland is fine for everything except the aurora itself — you will still need to drive out. If seeing it matters more than convenience, base yourself on the edge of town facing your dark spot.

Common questions about the aurora borealis in Östergötland
Can you see the aurora borealis from Östergötland?
Yes. On the last 10.0 years of NOAA Kp records, Östergötland had about 2.4 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 Östergötland?
Kp 7. Östergötland sits at geomagnetic latitude 57.6°, 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 Östergötland?
September, November and March. 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 Östergötland never gets fully dark, so nothing is visible however strong the storm.
Where can you escape the light pollution near Östergötland?
The centre of Östergötland reads Bortle 4. The nearest sky at Bortle 4 is about 7 km west-south-west around Linköping. On a marginal night that drive matters more than the forecast does.
Where is the nearest place to Östergötland with reliable aurora borealis?
Bodø, Norway — 977 km north. It needs only Kp 3 and averages 171.4 viable nights a year against 2.4 in Östergötland.
