How to see the northern lights from Tromsø

Look north. The aurora appears low on the northern horizon for Tromsø unless the storm is strong, so you need a clear, unobstructed view that way.
Get dark. Leave city lights behind — the darker the sky, the fainter an aurora you can catch. A new or low moon helps.
Time it. Activity peaks around magnetic midnight (about 10pm–2am local). Clear autumn-to-spring nights are best.
Check the live reading. A gust of solar wind gives only 15–60 minutes' warning, so watch the live Kp and the space weather dashboard on the night.
