After suffering from little financial support since the late 80th, international cooperation is pushing scientific efforts since the 90th. In line with a cooperation with the Institute for Radio Astronomy of Bologna addional equipment and observers have been available between 2000 and 2004. Amongst other instruments, a radar and a spectrograph have been used. Field work was conducted during several weeks in summer.
Preliminary report from 2002
Final report from 2004
The Hessdalen Lights are not a single phenomenon but different phenomena. The light can consist of several smaller units, which can seperate from each other and fly into different directions. There is no correlation to solar activity.
Photometric measurements suggest that the lights produce an energie up to 100 kilowatt.
The phenomenon can produce echoes on radar even when it is not visible. This indicates highly ionized air.
The VLF antenna showed some anomalous signals with doppler features. But there is no final proof that those signals are linked with the Hessdalen Phenomenon.
The sceptical scientist Matteo Leone showed that a certain amount of the EMLBA observations could be explained by car lights. The responsible scientist Massimo Teodorani could not provide convincing argument against Leone´s claims. Instead, he pointed to the considerable number of undoubted measurements.
The opinion of Hessdalen Germany: Misinterpretations of car lights cast a shadow on research on the Hessdalen Phenomenon. It should be a goal to avoid such kind of confusions in publications.
