The scale ranges from 0 to 9 where a value of 0 means that there is very little geomagnetic activity and a value of 9 means there is an extreme geomagnetic storm.
But remember that even though the KP index shows moderate to high activity, there is no insurance that you will be able to see the lights since the northern lights are a natural phenomenon and when it comes to nature, there are no guarantees! It's also good to keep in mind that the lights have been seen when the KP index showed 0.
