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 2.33
In 0 hour and 15 minutes, the aurora is predicted to be kp 2.00
In 0 hour and 30 minutes, the aurora is predicted to be kp 2.00
In 0 hour and 45 minutes, the aurora is predicted to be kp 1.67
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).
- 19th October 2016
Tonight’s estimated aurora level:
Level 2 – Low
Auroral activity should be at low levels. Weather permitting, aurora displays may be visible overhead or on the horizon in Bodø (Norway), Sodankylä (Finland), Kiruna (Sweden) and Siglufjörður (Iceland).
No significant geomagnetic activity expected.
3 Day Forecast

- 19th – 21st October 2016
The geomagnetic field is expected to be at quiet to unsettled levels on day one (19 Oct) due to persistent, but waning, negative polarity CH HSS effects. Quiet conditions are expected on days two and three (20-21 Oct) as CH HSS effects fully wane.
Predicted kp numbers for the next 3 days:

Time now in UTC (Universal Time) is: 21:59 23/10/16
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.
