Hessdalen phenomena

The Hessdalen lights

The beginning

In 1981 the first observations of unexplainable lights were reported at Hessdalen. The valley is situated in Trøndelag, 120 kilometers south of Trondheim.

The observations were described as moving lights on the sky and were seen multiple times during both night and daytime.

Strong lights

In the following years from 1981 several people reported to have seen the strong lights.  Even physical objects moving very close to the ground, buildings and people were seen on the Hessdalen skyline. 

Sometimes the lights were so bright that the ground was flooded with lights. 

The light phenomena could last for hours.

Theories

A lot of people from all over the country travelled to Hessdalen in hope of experiencing the phenomena themselves.

Different theories were soon to be launched, and someone even believed UFOs were flying over Hessdalen at lightning speeds.

Supernatural?

However, not everyone believed in these supernatural explanations and for years the locals were harassed when talking about the phenomena in public.

In 1983 different scientists started to dig into the phenomena and the Hessdalen lights became scientifically approved.

Science

In 1984 a 24 hour-surveillance of the valley was set up. 

Radars, electromagnetic equipment, low fi radio receivers and other high tech installations started to monitor the skies.

Soon a numerous number of observations were registered. None of these could be scientifically explained.

No explaination

The scientific project, as well as the technical surveillance, are still in operation at Hessdalen. 

For the time being (2020) no one has been capable of fully explaining what causes the Hessdalen lights.
