Best Viewing Tips
🕙
Best time: 10 PM – 2 AM
Aurora peaks around magnetic midnight. The hours either side of midnight local time give the highest chance — especially 11 PM–1 AM.
🌑
Escape light pollution
Drive at least 20–30 km from city centres. Rural areas, hilltops, lakeshores, and open fields all work well. Dark-sky parks are ideal.
🧭
Face north (in northern hemisphere)
Look toward the northern horizon. Aurora moves — scan a wide arc from NW to NE. In the southern hemisphere face south.
👁️
Let your eyes adapt
Give your eyes 15–20 minutes to dark-adapt. Avoid looking at phone screens. Faint aurora often looks green to a camera before the naked eye sees it — try a 10-second exposure.
📸
Camera settings
ISO 800–3200 · f/2.8 or wider · 5–20 sec shutter · manual focus to infinity. Modern smartphone Night Mode works surprisingly well too.
🌤️
Watch the weather too
Clear skies are essential. Even Kp 8 is invisible through clouds. Check cloud-cover forecasts (e.g. Windy or Clearoutside) alongside the Kp index.
