Summary

On August 13, 2013, a witness in Villérupt (France) observed a bright point in the sky moving in a straight line at a moderate speed with constant brightness. Suddenly, the object increased its luminosity, drawing the witness's attention. Although the event was somewhat unusual, the details provided were coherent and precise, lending credibility to the report. After a more in-depth investigation, it was determined that the phenomenon was a satellite reflection.
