*Impossible to watch at Northern light due to constant daylight
Note: This list, gives some interesting/practical links (in alphabetical order) in relation with the observation and the understanding of the aurora phenomena. This list is not exhaustive, and you are very welcome to suggest new links through our contact form.
You will find updated solar activity previsions, as well as auroral activity previsions, with clear explanations to understand the data. Multilingual website.
The official website of Alaska Fairbanks University, gives a 21 days forecast for auroral activity in both hemispheres, as well as some practical information.
NOAA - National Oceanic and Atmospheric Administration
The prestigious American agency provides most of “space forecasts” data used by the worldwide scientific community.
Northern Eye : is a free app' that allows you to follow the aurora forecasts for the 3 next days (with information on the Kp, Bz, the solar windspeed, etc).
The Kp-index is the global geomagnetic storm index. It ranges from 0 to 9, where a value of 0 means that there is very little geomagnetic activity and a value of 9 means extreme geomagnetic storming. Depending on your geomagnetic latitude (were you are), and on the Kp value, you will know if there is any chance for you to see an aurora.
How does the Kp-index work?
The table below shows you until which latitude you will be able to observe the Auroral Oval, depending on the Kp strength.
|Kp||Geomagnetic latitude||Auroral activity|
|Kp 0||66,5° or higher||Very low|
|Kp 5||56,3°||Minor Storm|
|Kp 6||54,2°||Moderate storm|
|Kp 7||52,2°||Strong storm|
|Kp 8||50,1°||Severe storm|
|Kp 9||48,1° or less||Extreme storm|
Example: With a Kp 0; you can observe an aurora in Tromso in Norway, with a Kp 5; you can see the aurora all the way to Edinburg in Scotland, and with a Kp9 (the maximum that is possible), you can view an aurora all the way to Marseille in France.
