Hessdalen AMS
Hessdalen AMS is the abbreviation for Hessdalen Automatic Measurement Station (automatic measuring station Hessdalen ).
This is an automatically operating since August 7, 1998 for the registration of unidentified station, suspended light phenomena near the mountain valley Hessdalen in Norway, the so-called Hessdalen lights. The station is equipped with multiple cameras and optical equipment, a magnetometer, a weather station and sensors for electromagnetic radiation. It is operated station of the college of Østfold.
Nature and origin of the Hessdalen phenomenon are still a matter of controversy and could, despite several years of studies not yet been clarified.
Background
In December 1981, unusual light phenomena was seen in the area of Hessdalen first time. According to reports, the lights could move slowly floating, stop, stop up to one hour and accelerate to high speeds.
The lights were seen at various points: High in the sky, close to the ground, about houses, but mostly on mountains or in the vicinity thereof. Showed descriptions and photos that the lights can take different forms and colors.
Investigations
Project Hessdalen (1983-1985)
To study the phenomenon in 1983, the project Hessdalen by Erling P. beach, diploma in electrical engineering, was founded.
Coordinated the beach about 35 field investigators on site, who carried out the observations and measurements. The project had to watch the goal of the objects and record with technical devices such as cameras, radar, laser, infrared devices and magnetometers to learn more about the nature of the phenomenon. The first observation phase took place until February 26, 1984, of January 21. A second phase in 1985 was inconclusive because of difficult weather.
Does the project support from the Norwegian Research Society for defense was ( Forsvarets forskningsinstitutt ) with technical equipment. Different universities and individuals were involved through consultation and analysis. The cast included O. Andreassen from the Institute of Theoretical Astrophysics, Jan Egeland, Institute of Physics, University of Oslo, J. Havskov from the Institute of Solid State Physics, University of Bergen, J. Allen Hynek of the astronomical faculty of Northwestern University, JA Tellefsen of the Royal Institute of Technology, Stockholm, and Harley D. Rutledge of the University of Missouri.
The result of the observations were 188 unusual sightings, of which 53 ( equivalent to 28 %) have not been identified and classified as " Hessdalen phenomenon ". Among them are two sightings in which the objects behave in very good data base extremely unusual. In addition to the visual perception of the objects could also be detected with radar and laser, other devices provided no or doubtful results. A conclusive explanation for the Hessdalen phenomenon could not be found, but this also was not in the foreground, but the collection of reliable data.
New Project Hessdalen (from 1995)
In 1994, ten years after the completion of Project Hessdalen, the first international workshop on the unidentified atmospheric light phenomena in Hessdalen was held ( First International Workshop on the Unidentified Atmospheric Light Phenomena in Hessdalen ). 27 scientists from eight countries took part, especially specialists for ball lightning phenomena. The workshop concluded with the result that it was not a question at the Hessdalen phenomenon to ball lightning and the phenomenon with the current models could not be clarified. It was suggested that research continues to deepen and to collect more data. As a result, was founded in 1995 by the College Østfold the New Project Hessdalen, again under the direction of P. Erling beach. The main work of the project was to develop an automatic monitoring station to monitor this and to evaluate the data. The completed in 1998 Hessdalen Automatic Measurement Station is the result of this project.
EMBLA project (1999-2004)
1999, the project EMBLA was launched by an Italian team of scientists. The project was funded by the Institute for Radio Astronomy in Bologna ( Istituto di Radioastronomia di Bologna, IRA) and the University of Østfold. EMBLA should continue the project Hessdalen and examine the phenomenon with modern equipment. The project was led by Ph.D. Massimo Teodorani, an astrophysicist at the Institute for Radio Astronomy, and Gloria Nobili, a physicist at the University of Bologna.
In multi-week observation periods from 2000 to 2004, the researchers were able to confirm the data of the project Hessdalen and multiple document the sighting unidentifiable atmospheric light phenomena. One explanation for the phenomenon could not also provide the project EMBLA. The document EMBLA 2002 - An Optical and Ground Survey in Hessdalen, the authors speculate about the possibility of atmospheric plasma as the origin of the phenomenon, as well as about an extraterrestrial intelligence, or simple fraud. However, none of the theories is convincing. The authors feel that further advances in research for very difficult as long as not substantially greater resources for the study are available.
Criticism of the investigation
Skeptics such as the physicist Matteo Leone of the University of Bari doubt the methods of Project Hessdalen and project EMBLA. Leone doubts that the EMLA data demonstrate a hitherto inexplicable phenomenon. He suspects that it is merely a nearby road car headlights at the sightings and leads the seemingly correlating measurements back to incorrect operation of the equipment or data analysis. However, Leone acknowledges that photographs and eyewitness accounts prove the existence of a phenomenon.
