Unusual lights have been reported here since the 1940s or earlier. Especially high activity of Hessdalen lights took place from December 1981 until the summer of 1984 when lights were observed 15–20 times per week. Since then, the activity has decreased and now the lights are observed some 10–20 times per year.
The Hessdalen light most often is a bright, white or yellow light of unknown origin. On February 8, 2015, the Live Cam2 (NW) recorded again a strange light floating above the ground level.
This kind of mysterious entities or supernatural beings are seen worldwide. Despite intensive research and analysis on this phenomenon, there is no explanation as to what it could be.
