UFO in Ain 1954

Summary

On the night of November 20, 1954, between 1:30 and 3:30 AM, several people in the French region of Ain observed a luminous phenomenon in the sky. The only collected testimony described an unidentified object (PAN) moving vertically in a zigzag pattern from the southeast (SSE) in a clear sky. The observer noted that the PAN alternated between bright and dark, surrounded by a halo. Although the observation was long and detailed, the GEIPAN investigators initially considered the possibility of an astronomical phenomenon, such as the presence of the star Sirius in the southeast at 1:30, moving toward the south. The halo could have been caused by an atmospheric veil originating from desert dust.

However, the lack of precise information about the exact direction of the observation and the imprecise estimation of azimuth and elevation led researchers to rule out this explanation with certainty. The testimony mentions a roughly estimated azimuth toward the SSE without temporal evolution, and the elevation was expressed in meters instead of degrees, making any deeper analysis difficult. Due to this lack of concrete data, the GEIPAN classified the case as "C" (lack of information). Although the PAN displayed unusual movements, it cannot be confirmed whether it was a real object or an optical illusion caused by the perception of a luminous point in darkness.
