Longyearbyen

Are you ready for an unforgettable adventure in one of the most remote and breathtaking places on Earth? Longyearbyen, the most northerly settlement in the world with a population over 1,000 people, is a spectacular destination that offers an extraordinary chance to witness the awe-inspiring northern lights. Nestled in the heart of the Svalbard archipelago, this charming town is surrounded by stunning mountains and vast arctic landscapes, making it the perfect base for your northern lights expedition.

Positioned well above the Arctic Circle, The Northern Lights season in Svalbard runs from late September until mid-March and the best time to view the auroras is typically between 6pm and midnight, while there is also a good period between 4am and 8am. For optimal viewing conditions, consider visiting during the Polar Night (from late November to mid-February), when the region experiences 24 hours of darkness, enhancing the visibility of the lights. In December and January, it’s even possible to see the Northern Lights around the clock – even in the middle of the day.

How are my chances of seeing the aurora today?

Many factors contribute to your likelihood of viewing the aurora in Longyearbyen. Geomagnetic activity, cloud cover and the amount of ambient light all play a big part. Check the forecasts for how good the viewing conditions are today.

Aurora Probability and Atmospheric Conditions

2%

There is a 2% chance of seeing the aurora overhead in the Longyearbyen area (forecast for 11 July 2026 at 2:03am UTC)

Kp 3.00

The Kp-index is a scale used to measure geomagnetic activity. It ranges from 0 to 9, with higher values indicating greater geomagnetic activity.

  • 0-2 (Very low) Far north, quite dim, and not very active.
  • 3-5 (Moderate) Can be seen further south, with increased brightness and activity. Chance of good viewing conditions nearer the pole.
  • 6-7 (High) Visible in many northern regions, with vibrant displays.
  • 8-9 (Extreme) Widespread visibility, often seen in areas much further south than usual, with intense and colorful displays.
HPI 39 GW

The Hemispheric Power Index (HPI) is a vital measure used to assess the strength of auroral activity at the poles. It estimates the total auroral energy input, with values above 20 GW indicating an aurora-active state. When the HPI reaches levels of 100 GW or more, it signifies a very significant geomagnetic storm, which can lead to spectacular auroral displays.

Bz -2 nT

Bz refers to the north-south orientation of the magnetic field embedded in the solar wind. It is measured in nanoteslas (nT).

When Bz is negative (southward), it allows solar wind particles to penetrate the Earth’s magnetic field more easily. A strong negative Bz is often associated with increased chances of seeing the Northern Lights.

Conversely, when Bz is positive (northward), the Earth’s magnetic field tends to block the solar wind, resulting in reduced aurora activity.

Bt 5 nT

Bt measures the overall power of the Interplanetary Magnetic Field (IMF) from the Sun; higher numbers (e.g., above 20 nT) mean more energy available for aurora.
