At KP 2, the aurora borealis is typically far north, faint, and not very active. However, it may still be visible north of Selje(NO) (latitude 62.3°N eller høyere) under favorable conditions. The direction of the magnetic field (Bz) suggests that there is a moderate likelihood of strong northern lights if there is activity (KP) in your area.

How to read the northern lights forecast in an easy way

To understand the northern lights forecast, you need to know a bit about what the KP and Bz values mean. The KP value provides information about how far south the northern lights are visible. Imagine an oval centered over the North Pole, and this oval represents the northern lights. The higher the KP value, the wider the oval, and the farther south the northern lights can be observed. The exact southern limit is determined by latitude. On this page, you’ll find a table that makes it easy for you to determine the minimum KP required to see the northern lights from where you live.

The Bz value tells us the direction of the interplanetary magnetic field and how solar particles react with our atmosphere. In practice, we can use this to say something about the strength of the northern lights. If Bz has a negative value, it positively influences the northern lights. The more negative it is, the stronger the northern lights become. If it is strongly positive, the northern lights weaken, and it may not be possible to see northern lights at all.

In summary, a high KP in combination with a negative Bz is good for the northern lights. We have summarized the northern lights forecast in text format to make it easier to understand. Note that the information at the top of the page is the freshest available. The time from measurement to atmospheric impact and the creation of northern lights varies between 15-60 minutes depending on the speed of the solar wind. The northern lights are ephemeral, and the forecast is not always entirely accurate.

The best northern lights forecast we have is our own eyes. If you see the northern lights, please report when and where in the Facebook group so that more people can be made aware of the activity. Together we are strong!
