# Yes; a residue of the lights is a distinct natural luminous phenomenon of the valley.

Yes; a residue of the lights is a distinct natural luminous phenomenon of the valley.

**Still possible** Answers **1** questionPublished0

## Where it stands

**Still possible** Its tests haven't settled it: three pieces of evidence for, one against. It needs two reviews to be accepted.

## What it predicts

- After removing aircraft, vehicles, stars and satellites, a residue of detections remains at a rate above zero.
- The residue shows properties no known source has (radar returns without visual counterparts, stationary lights for over an hour).
- Multi-camera triangulation places residual lights at short range inside the valley.

## What would rule it out

- A systematic classification of the station's detections over several years in which every event is matched to a known source, with no residue.

[In 1984 a radar tracked a light at about 8,500 m/s, and magnetic disturbances often coincided with sightings.](https://mysteriesdept.com/mysteries/hessdalen-lights/evidence/EVD0D0NDPN83EPV/in-1984-a-radar-tracked-a-light-at-about-8-500-m-s-and)

Most likelyNo; the lights are misidentified vehicles, aircraft, astronomical objects and instrumental artefacts
