## Guides

- [Best time to see the northern lights: month by month, from ten winters of data](https://aurora.report/blog/best-time-to-see-the-northern-lights/): The best months are the ones that are both dark and clear. Here is when aurora cameras saw it most often, and when low cloud was rarest at twelve destinations, from ten winters of airport reports.
- [Does a full moon ruin the northern lights? What our camera data shows](https://aurora.report/blog/full-moon-and-the-northern-lights/): A full moon does not ruin the northern lights, but it hides the faint ones. When we checked moonlit camera frames by eye, about half of the aurora the cameras recorded was still worth seeing for a person.
