The “Hessdalen Lights” Mystery.

What flies over Hessdalen Valley in Norway? Investigation into the Hessdalen Lights continues as scientists set up equipment to capture live and analyze the mysterious valley lights. Although the frequency of the sightings has dropped significantly over the last years, something or someone keeps visiting this remote area as if trying to grab public attention.

The unexplained occurrences of aerial light orbs which have become known as the “Hessdalen Lights” due to the location of the sightings – the Hessdalen Valley in the municipality of Holtålen in Sør-Trøndelag county, Norway, are one of the mysteries that have not been solved yet in spite of its repetitive nature and a few decades of recorded history.

The sightings date back to the 40’s of the 20th century, however the peak wave was recorded in the period between December 1981 and the summer of 1984 with as many as 15 to 20 sightings per week. The sightings became so popular that they actually converted into a substantial increase in tourist traffic and became the key attraction in the area. Travelers from all corners of the country would stay up all nights to see the lights with their own eyes. Currently the frequency of the sightings has dropped to 10-20 per year. Which means they are a flight ticket and B&B accommodation away if you fancy to give it a shot yourself (Here is a link to the the page on the Project Hessdalen official site where you will find some useful information for visitors, including accommodation details: Holtålen municipality tourist information.)

The specifics of the lights recorded so far are as follows: most often the lights are bright and white or yellow in color. They hover or float above the ground level. Sometimes the light can be observed for more than one hour. Other than these most popular occurrences a few other types of unexplained lights have been seen in the Hessdalen Valley. What makes the Hessdalen lights different from other similar sightings is the fact that they have become a subject of close investigation with the use of electronic devices, codenamed “Project Hessdalen”, which started in

1983 by initiative of UFO-Norge and UFO-Sweden organizations. In the years 1983-1985 the investigation was mostly field research. In 1998 the Hessdalen AMS automated scientific research station was built in the valley to register and record the appearance of lights.

Next, the EMBLA program was initiated (Embla is an Old Norse name of uncertain meaning, probably from the Proto-Norse name *Elm-la deriving from the Ancient Germanic name *Almilōn (Old Norse almr = ‘elm tree’. More info here). Scientists and students work together in an effort to discover the true nature and the origin of these lights. Key research institutions participating in the project are Østfold University College (Norway) and the Italian National Research Council.

In the course of the research a few possible explanations of the phenomenon have been offered as follows:

• One explanation attributes the phenomenon to an incompletely understood combustion process in the air involving clouds of dust from the valley floor containing scandium. Some sightings though, have been identified as misperceptions of astronomical bodies, aircraft, car headlights, and mirages (so nothing new in this department).

• One recent hypothesis suggests that the lights are formed by a cluster of macroscopic Coulomb crystals in a plasma produced by the ionization of air and dust by Alpha particles during radon decay in the dusty atmosphere. Several physical properties (oscillation, geometric structure, and light spectrum) observed in Hessdalen lights phenomenon can be explained through the dust plasma model. Radon decay produces alpha particles (responsible by helium emissions in HL spectrum) and radioactive elements such as polonium.

• Another hypothesis explains HL as a product of piezoelectricity generated under specific rock strains (Takaki and Ikeya, 1998) because many crystal rocks include quartz grains which produce an intense charge density. In a recent paper,based in the dusty plasma theory of HL, it is suggested that piezoelectricity of quartz cannot explain a peculiar property assumed by the HL phenomenon — the presence of geometrical structures in its center.

If you need these explanations elaborated on you can find some additional information on the Wiki page devoted to the Hessdalen lights under this link:

So far no one has been able to conclusively determine what the Hessdalen lights are (or what they are not). In spite of the fact that the lights have been presenting themselves in the same spot for many decades now as if begging for attention, despite numerous video recordings and in-depth analyses of the phenomena by established scientific institutions, the mystery remains unsolved.
