Tonight in Stirling

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 Stirling sees the aurora borealis most winters.
Hours of true darkness, month by month
| Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|

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

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 Stirling you will find Cambuskenneth Abbey, Doune Castle and Castle Campbell.
Keep the daylight loose: the sky decides the evening, and the forecast can turn within a few hours.

Common questions about the aurora borealis in Stirling
Can you see the aurora borealis from Stirling?
Yes. On the last 10.0 years of NOAA Kp records, Stirling had about 22.5 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 Stirling?
Kp 5. Stirling sits at geomagnetic latitude 58.4°, 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 Stirling?
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 July the sky over Stirling never gets fully dark, so nothing is visible however strong the storm.
Where can you escape the light pollution near Stirling?
The centre of Stirling reads Bortle 7. The nearest sky at Bortle 4 is about 24 km north-west. On a marginal night that drive matters more than the forecast does.
Where is the nearest place to Stirling with reliable aurora borealis?
Inverness, United Kingdom — 152 km north. It needs only Kp 5 and averages 28.7 viable nights a year against 22.5 in Stirling.
