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.

Fairbanks, Alaska, is known for being one of the best places in the world to witness the mesmerizing northern lights, also known as the aurora borealis. The city's location right under the Aurora Oval makes it a prime spot for viewing this natural phenomenon.

The chances of seeing the northern lights in Fairbanks are relatively high compared to many other locations around the globe. On average, the aurora can be seen about 200 days a year in Fairbanks, with peak viewing season being from late August to mid-April.

Of course, several factors come into play when it comes to spotting the northern lights, such as solar activity, weather conditions, and light pollution. Clear, dark nights away from city lights are ideal for witnessing the aurora in its full glory.

So, if you find yourself in Fairbanks during the aurora season, be sure to keep an eye on the night sky, as you just might be treated to a breathtaking display of dancing lights.
