I think they have special cameras when they take pictures of auroras. I admit the colours in pictures are sometimes very bright. Usually auroras are green and like a big snake moving across sky. That picture is close to my experience.
As a child I was a bit afraid when very bright auroras appeared while I was walking home through dark forest. Nearest streetlamps were over 30 km away, so it was really dark. In October you can add the voice of ice breaking in the lake when temperature is dropping fast below -20 Celsius. It´s a thunderlike voice.
Unfortunately many visitors who come to see northern lights are unlucky. There is no northern lights sometimes for weeks ( depends on sun spot activity and solar flares) and sometimes it´s too cloudy. For example last December it was very quiet. I waited on river ice for hours. Hardly any northern lights. One night I saw two Japanese girls also waiting northern lights to appear. It was windy and -25 Celsius. Sadly they saw nothing.
BTW Arctic circle also changes position every day. It is moving to north 15 m per year.
