Is the aurora visible in Aberystwyth tonight?

Right now

Not tonight.

Kp is 0.3. Aberystwyth needs Kp 8+ for the oval overhead — right now it’s not reaching Aberystwyth.

Tonight's peak is forecast around Kp 5.0 (Minor storm). The forecast still depends on darkness, cloud and the moon at your exact spot.

Reliable about 30 minutes ahead — cloud decides the rest.

Aberystwyth only catches the aurora during strong geomagnetic storms — it needs roughly Kp 8+ for the northern lights to come into view. Here's tonight's live space weather and how to plan around it.

How to see the aurora from Aberystwyth

Face north and find a clear, low horizon in that direction. Everything else — dark skies, adapted eyes, the camera trick — is the same anywhere on Earth, so it lives in the how to photograph the aurora guide.
