Fluorescent print on the 200-krone banknote

On the 200-krone note there is an invisible comet to the left of the portrait of Kristian Birkeland. It is only visible when the note is exposed to ultraviolet light. Fibres in the paper and a narrow strip on both sides of the holographic foil strip will also reflect the light.
