Will there be aurora tonight where I am?

Aurora visibility depends on your latitude and the current Kp index. Share your latitude on this page and Coronaut calculates whether tonight's Kp is enough to push the aurora oval to your location — with a drive-time estimate if you'd need to head north to see it.

How much Kp do I need to see aurora?

At latitude 66°+ any Kp will work. At 62° you need Kp 3+, at 58° Kp 5+, at 54° Kp 6+, at 50° Kp 7+, at 46° Kp 8+, and below 46° you need Kp 9 (extreme storm).

What time of night is best for aurora?

Aurora is most likely between 22:00 and 02:00 local solar time (magnetic midnight). Get away from city lights and let your eyes adjust for at least 15 minutes.

Does cloud cover matter?

Absolutely — even a strong aurora is invisible through overcast. Coronaut overlays cloud cover from Open-Meteo on the aurora verdict so you know whether to drive to clearer skies.

Will there be aurora tonight?

Enter your latitude and see immediately whether tonight's Kp index is enough for aurora at your location — and if not, how far north you'd need to drive. Every calculation uses the live planetary Kp from NOAA SWPC.

How to read the verdict

Aurora appears when the auroral oval reaches your latitude. The oval expands equatorward as Kp rises. Rough table for your reference:

Kp 3+ — visible at 62°N (northern Norway, Alaska).
Kp 5+ — visible at 58°N (Scotland, southern Sweden, Vancouver).
Kp 6+ — visible at 54°N (Edinburgh, Copenhagen, Ottawa).
Kp 7+ — visible at 50°N (northern US, Berlin, London).
Kp 8+ — visible at 46°N (Milan, Portland OR, Toronto).
Kp 9 — visible below 46°N (Rome, Chicago, Madrid) — Carrington-class.

Frequently asked

Will I actually see aurora, or does the Kp lie?

The Kp gives you the odds. Reality also needs: dark sky (get away from city lights), clear weather (Coronaut overlays cloud cover on the main dashboard), and looking in the right direction — poleward. Give your eyes 15 minutes to adjust.

What time should I look?

Between 22:00 and 02:00 local time is peak. This is when your location rotates under magnetic midnight — the strongest section of the auroral oval.

Can I set up an alert?

Yes — the full dashboard lets you set an "aurora reaches my latitude" alert. When Kp climbs high enough for your location, the browser pings you. Email + push delivery is on the Pro tier ($5/mo).

What if I need to drive north to see it?

Coronaut computes a drive-time estimate in the Aurora persona verdict on the main dashboard — how many km north to reach the oval and roughly how long the drive takes at highway speed.
