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 -1.00
While all the other forecasts are using satellite and scientific data. The Daily aurora forecast is predicted at 3pm Finnish time (1pm Universal Time) by a person. (The computer models and predictions are great, but using real life experience and pattern recognition is something they can’t do).
- 14th March 2016
Tonight’s estimated aurora level:
Level 4 – High
Auroral activity should be at high levels. Weather permitting, aurora displays may be visible overhead or on the horizon in Trondheim (Norway), Vaasa (Finland), Sundsvall (Sweden) and Faeroe Islands.
3 Day Forecast

- 14th – 16th March 2016
Solar wind parameters are expected to become enhanced beginning late on day one (14 Mar) through the end of day three (16 Mar) due to the effects of a co-rotating interaction region (CIR) followed by the influence of a south polar-connected, negative polarity coronal hole high speed stream (CH HSS).

Time now in UTC (Universal Time) is: 05:45 31/05/16
Why do we use UTC?
UTC (Universal Time) is used in science, weather, aviation, military and many other fields. It eliminates confusion with multiple time zones and daylight saving. For more information on UTC click here
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. These 3 components are the most important components of the solar wind (when it comes to Aurora Borealis). Note the Bz gauge works backwards. 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 Northern Lights where you are?
The Northern Lights are most often seen in the Lapland regions of Finland, Sweden and Norway along with Iceland and Greenland. But during high activity, auroras are often visible from much lower latitudes, often including Scotland, Ireland, Denmark, Estonia and more. This table allows you to see what Kp level is typically required see aurora borealis where you are in the event of high geomagnetic activity.
