As a study published last year in Frontiers in Earth Science shared, “rare and unusual atmospheric lights have been reported in the valley of Hessdalen in Norway for over a century.” Yet, “in spite of their irregular occurrence—i.e., 15 to 20 times per week from 1981 to 1984 and 10 to 20 times per year nowadays—the Hessdalen lights (HL) have been consistently observed and possess a series of recurring features.”

The study then outlines their features. Firstly, they have the appearance of a free-floating light ball with dimensions ranging from decimeters up to 30 m. Secondly, they are characterized by geometric structures that are often accompanied by small, short-duration pulsating “spikes” in the high frequency and very low frequency radio ranges. Thirdly, they show an absolute luminosity that has been estimated to be 19kw, and lastly, they have a time duration that ranges from seconds to hours.
