Next we need to look at the KP Index. We can check the KP Index of the night and the next few days at http://en.vedur.is/weather/forecasts/aurora/. On a scale of 0 to 9, the higher the KP Index, the stronger the aurora is. Be reminded that the KP Index changes every hour and minute. It can be KP 2 at this moment, and rises up to KP 6 in 3 hours. So we recommend travelers chasing the aurora on their own to pay attention to the KP Index 3 or 4 hours later in addition to the current one. An index of 5 is already the dancing aurora that many travelers wish to see. For a lower KP index like 2, we can only expect relatively weak auroras that appear like a mist of pale green. We don’t advise driving into the wilderness every night to wait for the aurora borealis since it’s physically exhausting. The wiser way to do instead is to do your preparation work well and only go to the cloudless area on a high KP Index day.

Chasing the aurora borealis is an activity that requires high persistence. The sighting of it and when will it appear are all unknown. Therefore, bundling up to keep yourself warm is very important. However, that doesn't mean just putting all the clothes on. The ideal outfit in the Arctic region is “Layering up”. First wear thermal tops and pants as the inner base layer, then sweater and fleece jacket in the middle and water- and wind-proof coat or down jacket as the outerwear. Don't forget to wear a pair of water-proof snow pants, thick wool gloves and socks. Scarf, hat and snow shoes are also important to prevent heat loss through your head or feet.
