Know when the sky
will put on a show.
Pxie's aurora forecast tonight gives the chance of seeing the northern or southern lights at any location, and the best time to look, so your guests are outside at the right moment.
Aurora forecasts are included from the Builder plan.
Coverage: Anywhere on Earth, northern and southern lights.
Northern lights forecast, for every location.
Tonight's chance, anywhere
A 0 to 100 chance for any coordinates, with darkness, distance to the aurora oval and a data quality score, updated every few minutes.
The chance of seeing the aurora
An optional adjustment for moonlight, light pollution and cloud, so a strong aurora behind clouds isn't mistaken for a great night.
When to look
A plain-language insight with an estimated time to peak, so tours depart at the right moment.
Northern and southern lights
The same answer for any latitude and longitude, in both hemispheres.
Aurora data, one question at a time.
Aurora chance
Send any coordinates and get a 0 to 100 chance of aurora right now, with the darkness, distance to the oval and solar wind conditions behind the number. It suits lodges, tour operators and apps that need one clear answer.
Aurora oval
The live boundary of the aurora for the northern or southern hemisphere, ready to draw on a map, with an optional intensity grid. Map apps and live dashboards use it to show where the lights are strongest and how far they reach.
Substorm forecast
A substorm is the sudden burst when the aurora brightens and races across the sky. The forecast gives the current phase, an intensity score and the estimated time window until the next burst, so a tour can leave at the right moment. See how it works.
Visibility forecast
An optional adjustment for moonlight, light pollution and cloud, so a strong aurora under a bright moon or an overcast sky is not reported as a perfect night.
CME arrival
When the Sun throws out an Earth-directed eruption, the arrival forecast gives the window when it reaches Earth, days before the aurora it can trigger.
Solar wind outlook
A 96-hour outlook of solar wind speed that flags fast streams, which raise aurora odds several days out. Trips and events can be planned around the best nights well ahead.
Both hemispheres, anywhere
