Aurora borealis observed in the North Atlantic

Summary

In November 1957, a civilian observer in the North Atlantic reported two bright red areas in the sky. The atmosphere was clear, and the objects were located north of the zenith, stretching in an east-west direction. Although it could initially seem like an aerial or balloon phenomenon, investigators concluded it was a boreal aurora. This type of phenomenon was particularly prominent that year, matching the sighting description. The lack of photographs and additional data did not prevent a clear conclusion.

The classification of the case as an astronomical phenomenon shows how researchers of the time could differentiate between aerial objects and natural phenomena. This document, although brief, reflects the methodology used to evaluate sighting reports. Despite the simplicity of the description, an accurate assessment was achieved thanks to the context of the year and the location of the sighting.
