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.
