Nantes 2013, Observation of triangular lights

Summary

On October 20, 2013, two people noticed a set of evenly spaced lights forming a triangle in the sky. Although only one witness account was collected, it was concluded that this was a misidentification of the star cluster known as the Hyades. The observed lights matched the position of the stars in this cluster. Additionally, the only orange light seen could have been the star Aldebaran, which is near the Hyades. The error was not in the visual perception but in the interpretation influenced by context: surprise, fatigue, a night walk, and possible clouds that created the illusion of movement. The case was classified as "A", meaning a clear identification of an astronomical explanation.
