Hessdalen Scientific Campaign: 188 Observations in 5 Weeks
From January 21 through February 26, 1984, Project Hessdalen conducts its intensive scientific observation campaign in central Norway. Armed with radar, cameras, Geiger counters, seismograph, fluxgate magnetometer, spectrum analyzer, and infrared viewers, the team records 188 specific observations. Of these, 53 are of sufficient quality to be considered valid 'Hessdalen Phenomena.' Three types categorized: (1) white/blue-white flashing lights high in air, (2) yellow lights with red on top, sometimes flashing, (3) most commonly, slow-moving roundish yellow/white lights that can hover for an hour or more. Radar and camera evidence obtained but not with seismographs, Geiger counters, or IR viewers — suggesting geological activity and radioactivity are not involved. Objects appear 'not merely intelligent, but mischievous' — cameras failed 'mostly when we needed them most.'
Background
EVENT TITLE: Hessdalen Scientific Campaign: 188 Observations in 5 Weeks
EVENT DATE: 1984-01-21
EVENT TYPE: investigation
From January 21 through February 26, 1984, Project Hessdalen conducted an intensive scientific observation campaign in Hessdalen, Norway. The team recorded 188 specific observations of anomalous aerial phenomena using a variety of scientific instruments. This campaign aimed to gather data and understand the ongoing "Hessdalen Phenomenon."
The Incident
The "Hessdalen Phenomenon" began in November 1981 in the thinly populated valley of Hessdalen in central Norway. Residents reported sightings of anomalous lights that persisted through the 1980s and beyond. These luminous objects were typically observed at night, often appearing between mountains and hovering for extended periods, sometimes an hour or more, before rapidly ascending or accelerating horizontally.
The objects were observed singly or in groups. Some moved slowly, while others moved at great speed, performing simple or highly complex maneuvers. In addition to lights, metallic cigar-shaped objects were also sighted during the day. Notably, no sounds were ever associated with the phenomenon, despite the area's isolation allowing residents to hear distant vehicles.
Investigation
From January 21 through February 26, 1984, Project Hessdalen conducted a scientific observation campaign. The team was equipped with:
* Radar
* Cameras
* Geiger counters
* Seismograph
* Fluxgate magnetometer
* Spectrum analyzer
* Infrared viewers
Using this equipment, the team recorded 188 specific observations of the anomalous phenomena. Radar equipment tracked objects moving at speeds exceeding five miles per second (over 18,000 mph). The nature of the phenomenon resisted conventional explanation.
Significance
The Hessdalen Phenomenon is significant due to the sustained and observable nature of the unidentified aerial phenomena. The repeated sightings and the attempts to document them with scientific instruments make it a compelling case for further study. The fact that the objects resisted conventional pigeonholing, even after photographic and radar evidence was obtained, highlights the challenge in understanding these phenomena. The lack of sound associated with high-speed movement further adds to the mystery.
