Northern lights are common in the arctic region of the northern hemisphere and are caused by the solar wind colliding with the atmosphere. Recent years northern lights have been getting more common, caused by increased solar activity.
Ms Karlssons picture of the celestial animal has since become a viral success. It has been shared thousands of times on Facebook, but has also raised suspicion. Several people have been in contact with both SVT nyheter Norrbotten and the photographer herself, to question the authenticity of the picture.
– They think it is fake, but I can assure all sceptics that it's genuine, Ms Karlsson tells SVT nyheter Norrbotten.
