Florange 2011, luminous ball identified as a Thai lantern

Summary

A witness in the southern area of Thionville, in Moselle, observed on November 12, 2011, an orange glowing ball flying at low altitude from north to south. The description of the object and its trajectory, which matched the wind direction recorded that day, led to the consideration of a known phenomenon. After analysis, the GEIPAN concluded it was likely a Thai lantern. These objects, used in traditional celebrations, can reach high altitudes and are sometimes mistaken for unexplained aerial phenomena.

The "B" classification from GEIPAN indicates that the case has a plausible explanation—in this case, a Thai lantern. Although Thai lanterns are common in other countries, their presence in France can be surprising, especially if their use is unknown. This case is an example of how everyday objects can be misinterpreted as unexplained phenomena, highlighting the importance of meteorological and cultural analysis in the study of sightings.
