Northern Lights
at Hörgsland 1
One of the good places to experience the Northern Lights is at Hörgsland 1, a hidden gem nestled in the stunning Icelandic landscape. Located far from the light pollution of the cities, Horgsland offers a pristine vantage point where the aurora's colors seem to shimmer even more brightly against the dark sky. The vast, open spaces around Hörgsland, with their unobstructed views, make it an ideal spot for aurora chasers.
On a clear night, when the lights begin their dance, it's as if the entire sky comes alive, painting the heavens with light and color.
What is Aurora Borealis?
The Northern Lights (Aurora Borealis) result from disturbances in the Earth's magnetic field caused by charged particles from the sun. The Earth's magnetic field originates and is maintained by electric and convective currents in the Earth's fluid outer core. At the Earth's surface, about 90% of the magnetic field can be described by a dipole field, with the magnetic poles located approximately 10° from the Earth's rotational axis. The currents within the Earth change very slowly, meaning the magnetic field from the Earth's interior generally changes only over years and centuries.
A stream of charged particles from the sun, known as the solar wind, continuously impacts the magnetic field, bending it into a magnetosphere that largely protects the Earth and its atmosphere from these particles. Variations in the solar wind cause disturbances in the magnetic field, which can last from seconds to days. These disturbances are usually small compared to the strength of the magnetic field from the Earth's core, with significant disturbances being around 1-3% of the field's strength at the Earth's surface.
The Kp index is a simple measure of aurora activity, describing the strength of magnetic field disturbances on Earth. The Kp index ranges from 0 to 9, where 0 indicates minimal activity and 9 indicates maximum activity. Most often, the Kp value is between 0 and 3, with higher values being very rare. The Kp value is calculated as a weighted average of K-values from numerous geomagnetic observatories on Earth, where the K-value at each observatory is determined by the largest deviation in the horizontal strength of the magnetic field every 3 hours.
Your Checklist for Northern Lights viewing:
Look for a KP index of 2 or higher. While a KP value of 2-3 is usually enough to see the aurora in Iceland, higher values increase the chances of more vivid displays.
Check for Clear Skies, Make sure the sky is clear or has minimal cloud cover. If you can see stars, you have a good chance of spotting the aurora since stars are higher in the sky than the Northern Lights.
Find A Dark Location, Aurora visibility is best away from artificial light pollution. Stay in dark areas, preferably far from city lights. Winter months in Iceland (from September to April) provide long periods of darkness, which is ideal.
Dress Warmly, Layer up with thermal clothing, insulated jackets, hats, gloves, and waterproof boots. Temperatures can drop significantly at night.
- Thermos: Bring a thermos with a hot drink (like tea or cocoa) to stay warm during long periods outdoors
- iPhone or camera settings: Use a camera with manual settings to capture the aurora. A DSLR or mirrorless camera with a wide-angle lens, a tripod, and long exposure settings (5-30 seconds) will help you capture the best shots.
- Tripod is useful, A sturdy tripod is essential for keeping your camera stable during long exposure shots, which are necessary for photographing the Northern Lights
- Patience and time: The Northern Lights can be unpredictable. Be prepared to spend several hours outside waiting for the lights to appear. The best times are usually between 10 PM and 2 AM
