Aurora Visibility Score Calculator

Estimate your chances of seeing the aurora (Northern Lights) using a simple scoring model. This is an educational estimate—real visibility depends on local conditions.

Presets fill latitude + typical settings.
Higher latitude usually improves chances.
Higher KP = stronger geomagnetic activity.
Lower cloud cover is best.
Move away from city lights if possible.
A bright moon can wash out faint aurora.
Darkness is required.

How the score is calculated

We combine points for latitude, KP index, clouds, darkness, light pollution, and moon brightness into a 0–100 score.
