Hourly Aurora Forecast
Using real-time solar wind data from Nasa’s ACE spacecraft, matched with some computer modelling, we are able to display with reasonable accuracy, how the aurora will behave up to one hour in advance.
Image should be used as a guide only. Aurora may be seen slightly higher or lower than the image shows on any given night.
Right now, the aurora is predicted to be: Kp 1.67
Satellite based Kp data is temporarily unavailable, switched to magnetometer readings. System will auto swtich back to satellite based readings when it becomes available shortly. Magnetometer is located at magnetic latitude 48.40° North.
This happens a few hours per week, when it does, you can keep an eye on whats happening using the real-time solar wind tools below.
In 0 hour and 34 minutes, the aurora is predicted to be kp 2.00
In 0 hour and 47 minutes, the aurora is predicted to be kp 2.00
In 1 hour and 2 minutes, the aurora is predicted to be kp 2.00
System status: All good.
3 Day Aurora Forecast
Here are the predicted Kp numbers for the next 3 days. They can change at any time due to solar events, so you should check them at least once a day.

Why do we use UTC?
UTC (Universal Time Co-ordinated) is used in science, weather, aviation, military and many other fields. It eliminates confusion with multiple time zones and daylight saving. Once you find out the time difference between UTC and your own time zone, it is easy to read universal times. Click here to see what UTC is right now in North American time zones.

Solar Wind Gauges
These gauges are our own system, they are updated every 60 seconds directly from Nasa’s ACE spacecraft data. The data you see here is what the ACE spacecraft monitored only moments ago. It is the very latest live solar wind data available. These 3 components are the most important components of the solar wind (that we as aurora watchers are interested in). You can view all the components of the solar wind on our other solar wind tool here.
Gauges are updated every minute live (without the need for page refresh).

What Kp strength do you need to view aurora where you are?
To see the Northern Lights in the lower parts of Southern Canada you generally need Kp3+ levels. For the Northern USA states (excluding Alaska), you would usually need a geomagnetic storm for Northern Lights to be visible. Anything above (and including) Kp5 level is classed as a geomagnetic storm, so this is usually the golden number we all wish to see. Even if you are quite far north and have auroras at much lower kp numbers, a geomagnetic storm will turn the usual good aurora shows into amazing aurora shows.
