Darkness guide

Is twilight good or bad for aurora?

Darker is better. A darker sky creates more contrast, making faint colors and movement easier to see.

Full darkness

Best visibilityYour forecast

Sun below −18°

The sky offers its best contrast. Fainter aurora has a better chance of standing out.

Astronomical twilight

Good, with limits

Sun between −18° and −12°

The sky is not completely dark, but a moderate or bright display can still be clearly visible.

Nautical twilight

Difficult

Sun between −12° and −6°

Twilight still brightens the sky. Usually only vivid aurora will be easy to see with your eyes.

Bright summer sky

Poor visibility

Sun stays above −6°

The sky is too bright for routine viewing. An exceptional display may still appear, but it is not something to plan around.

Practical takeaway: aurora activity and darkness are separate. A strong forecast during twilight means aurora may be active, but the bright sky can make it harder to see.

Local viewing guide

Aurora inLerwick

Latitude
60.2° N
Location
Shetland Islands, United Kingdom

At roughly 60.2° north in Shetland Islands, Lerwick sits at a useful northern latitude where the aurora can appear during active periods. It is less dependable than in the far north, so a promising forecast should still be treated as an opportunity rather than a guarantee. Lerwick’s Shetland setting is among the United Kingdom’s most northerly, making it one of the country’s stronger aurora locations.

Lerwick has limited large-city glow, but nearby lamps and buildings can still reduce night vision. A safe open area outside the brightest part of the settlement will give both your eyes and a camera a cleaner view of the sky.

Autumn through early spring offers the most useful darkness. Summer nights can remain too bright for a faint aurora to stand out, even when space weather is active. Before heading out, compare the aurora forecast with local cloud conditions.

Aurora conditions can change during the night, so keep checking the forecast rather than relying on an earlier reading. From Lerwick, the best plan combines clear weather, an unobstructed northern horizon, patience, and as little artificial light as practical.

Why Is the Aurora So Hard to Predict?

Aurora forecasts can be useful, but they are never perfect. Solar activity, magnetic-field direction, cloud cover, and local darkness all make the northern lights harder to predict than most people expect.
