Norrsken

Holm is located on the 62:a latitude whereby there are good chances to see the northern lights a clear winter night with a lot of geomagnetic activity in the atmosphere. Below is automatically updated observations and forecasts in order to see the northern lights. Note that the times stated here in UT. Swedish time is + 1h + 2h in winter and summer.

3-hour forecast for the K index at high latitudes
The bar chart provides a forecast for the northern lights in the next few days. “Kp-index” indicates geomagnetic activity. 1-3= Calm magnetic, 4-5= Active magnetic, 6-8=storm, 9= Heavy storm. From the Kp index 3 there is a chance that the northern lights can be seen from Holm and Sundsvall (source).

Forecast for Northern Lights on 30 my (source / source)

The model calculates the energy of the aurora oval on 30 min based on data from the ACE satellite. At values <20 GW = little / no northern lights, 20-50 GW = opportunity to see near the northern lights, >50 = Great chance to see a lot of activity and movement in the sky. >100 GW = The Northern Lights can be seen hundreds of mil away. The model shows not only the intensity of the aurora oval, but also where you can see polar lights right now. The red line shows where you can see the low polar lights on the horizon. The Northern Lights can be seen alltås north of the red line. The probability is graded by color scale.

The redder the meters and fields show, the higher the chance of the Northern Lights.

What is Aurora Borealis?
Norrsken, aurora borealis, due to solar storms with electromagnetic energy which is thrown out from the sun and the earth's magnetic field results. Thereby energy is released and forms a beautiful glow. Want to learn more about the Northern Lights is a small movie about the whole process this, a Norwegian documentary this or more shorter American educational films this.
