Shetland Museum : Lerwick : Seek The Aurora

Lerwick

Nestled in the stunning Shetland Islands, Lerwick is not just the capital of Shetland; it’s a gateway to one of nature’s most mesmerizing spectacles: the Northern Lights. With its rugged coastline, charming harbour and rich cultural heritage, Lerwick offers a unique backdrop for witnessing the aurora borealis.

The best time to catch a glimpse of the Northern Lights in Lerwick is during the northern hemisphere winter, specifically from mid-October to mid-March.

How are my chances of seeing the aurora today?

Many factors contribute to your likelihood of viewing the aurora in Lerwick. 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

15%

There is a 15% chance of seeing the aurora overhead in the Lerwick area (forecast for 25 February 2026 at 11:06pm UTC)

Kp 2.00

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 50 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 -5 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.

Density 1.73 p/cm³

Solar wind density refers to the number of charged particles in a given volume of the solar wind, typically measured in particles per cubic centimetre (p/cm³).

A typical solar wind density is around 2.76 p/cm³.

The density of the solar wind affects how many particles reach the Earth’s magnetosphere. A higher density means more particles are available to interact with the Earth’s magnetic field. When these charged particles collide with the gases in the Earth’s atmosphere, energy is released in the form of light that we see as the aurora.

Speed 535.7 km/s

Solar wind speed refers to the velocity at which charged particles are ejected from the Sun’s outer atmosphere, known as the corona.

A typical solar wind speed is about 375 km/s. When both speed and density are high, the energy transferred to the Earth’s magnetosphere increases, enhancing the chances of seeing vibrant auroras.
