Project Hessdalen 1984: Final Technical Report Part One

This document is the Final Technical Report (Part One) for Project Hessdalen, dated January 5, 1985, authored by Erling Strand. The project was established to investigate unexplained light phenomena in the Hessdalen valley, Norway, which began appearing in December 1981. The valley, located south-east of Trondheim, became the site of a systematic research effort involving a working committee and an advisory committee, supported by various Norwegian academic and research institutions. The report details the methodology, instrumentation, and findings of the project's field work conducted between January 21 and February 26, 1984. The researchers utilized a variety of instruments, including cameras with gratings, a seismograph, radar (Atlas 2000), a spectrum analyser, a magnetometer, a laser, geigercounters, and IR-viewers. The report documents 188 reports of lights, categorizing them by 'goodness' (G-score) and 'strangeness' (F-score). The lights were observed to have various forms, including bullet-shaped, round, or 'Christmas-tree' shapes, and exhibited behaviors such as stationary hovering, slow movement, and high-speed travel, with radar tracking speeds up to 8500 m/s. The report discusses the results of these observations, noting that while some lights were identified as known objects like airplanes, others remained unexplained. The researchers found no direct correlation between the lights and seismic activity, but noted some potential correlations between the lights and magnetic pulsations. The report concludes that while the nature of the phenomenon remains unknown, it is a measurable event, and recommends continued research with improved instrumentation to better understand the phenomenon.
