Aurora Forecast

Hourly Forecast

Using real-time solar wind data from Nasa’s ACE spacecraft, matched with data obtained from a network of magnetometers located worldwide, we are able to forecast, with reasonable accuracy, how the Northern Lights will behave up to one hour in advance. The image shows estimated aurora activity now.

Image should be used as a guide only, it is based on predicted geomagnetic activity. Northern Lights may or may not be visible.

Right now, the aurora is predicted to be: Kp 0.33

In 0 hour and 31 minutes, the aurora is predicted to be kp 0.33
In 0 hour and 47 minutes, the aurora is predicted to be kp 0.33

What do Kp numbers mean?

System status: aurora forecast status All Good.

Daily Forecast

While all the other forecasts are using satellite and scientific data. The Daily aurora forecast is predicted at 5pm Finnish time (2pm 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).

    Daily forecast is temporarily unavailable (I’m on holiday). Normal service should resume late September. Sorry for any inconvenience.

3 Day Forecast

  • 12th – 14th September

    The geomagnetic field is expected to continue at unsettled to active levels until the arrival of the second CME from 10 September by mid to late on day one (12 September). Major storming (G2-Moderate) is likely just after the onset of the CME by late on day one with minor to severe storming (G1-G3, Minor-Strong) continuing into day two (13 Sep). Unsettled to G1 (Minor) geomagnetic storm conditions are expected for day three (14 Sep) as CME influence begins to subside.

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).

Aurora Service Magnetometer

Aurora Service HQ Magnetometer *Beta Testing* | How we built it
There is a lot of building work going on at Aurora Service HQ until around mid July (new roof!) and it is interfering with the magnetometer as they have tools and all sorts of ferrous objects near it, so we have temporary disabled it until the builders have gone (it was meant to be middle of June…).

How to read a magnetometer
It’s not exactly straight forward because magnetometers can be set up in 3 different ways so it’s important to know what system the magnetometer is using.

  • Geographic coordinates – North (X), East (Y), Vertical down (Z)
  • Geographic coordinates – Horizontal intensity (H), Declination (D), Vertical down (Z)
  • Geomagnetic coordinates – Magnetic north (H), magnetic east (D), Vertical down (Z)

Our magnetometer is set up using the first system, with X, Y and Z co-ordinates. When it comes to northern lights, we are usually most interested in the Y(By) trace. But if it is a commercial magnetometer like Dombås (above) they will instead use H, D and Z co-ordinates. It is often difficult to determine which system (2nd or 3rd) is in use as they both use the same letters. In the Dombås magnetometer above, TGO are still using analog magnetometers and they are using declination as their D co-ordinates. Which means they are using the second system on the list. So in this instance, it is best to use the H trace (which is a vector of X and Y) for aurora watching. The Z-component (vertical) normally is influenced most by induced electric currents in the Earth’s crust and is essentially the same on all systems. Although H and Y are what we typically monitor, the other traces do have their uses and if they start moving significantly, it is usually a good sign of strong geomagnetic activity.

What Kp strength do you need to view Northern Lights where you are?

Northern lights Europe Map

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.

If you are having difficulty seeing northern lights from your location, you are always welcome to visit us and come out aurora chasing personally with us, in the most northern town in the EU! Visit for more info.
