AuroraTonight answers one question: will you see the aurora tonight from where you are, and at what time.
We built it because the usual aurora dashboards show a Kp number and leave the rest to you. A Kp of 4 means a show in Edmonton and nothing in Chicago. So every page here starts from a place: the Kp it needs, tonight's Kp against it, the clouds hour by hour, how dark the sky gets and where the moon is.
What you get
- A live answer for 46 cities in Canada, the US, the UK, Australia, the Nordic countries, Iceland and Greenland, plus states, provinces and countries.
- Tonight's best window in local time and the direction to look.
- The 3-day and 27-day Kp outlook, a live aurora map and the latest storm days.
- How often each place gets a chance: aurora nights per year and by month, from the Kp record since 2015.
Who makes it
The site is written and maintained by the AuroraTonight Team. Each place page was researched for its own dark-sky spots, horizons and weather habits, with sources for every designation; how the numbers are computed is on the methodology page.
The app
The free app for iPhone and Android takes the same forecast to your phone and sends a push alert when the aurora is about to reach your sky. You never need it to use this site.
