It has to be dark and fairly calm weather
It is very important to look often. The most intense part of an aurora often lasts only between 10-30 minutes.
It can sometimes be hard to see the difference between a faint aurora and a cloud. If it is an aurora you can see stars through it. Auroras are often greenish and change shape in a different way than a cloud.
In Scandinavia the most active auroras are often seen before midnight.
The aurora can be photographed with an ordinary camera, but a fast film is recommended (for example 400 ASA).
