A luminous object with color changes in Strasbourg

Summary

On August 30, 2013, a witness in Strasbourg observed a luminous point descending silently from the sky along an S-shaped trajectory for about ten seconds. The object, roughly the size of a tennis ball, changed colors from blue to red, then green, and finally yellow before suddenly turning off. Although the report includes these visual details, it lacks precise information about the exact trajectory, light characteristics, and angular measurements that could help identify the phenomenon. Additionally, the testimony is singular, with no photographic or video evidence to support the observation. While the case is somewhat unusual, the lack of detailed data prevents a definitive assessment of its nature.
