An account in C�te-d'Or, France

On May 30, 1977 at 3:30 a.m., two people in a car observe a glowing ball of red-orange color above the town of Vitteaux. This ball is at low altitude and moves slowly in a south-to-north direction. No sound is heard during the observation, which lasts 5 to 6 minutes. This old case was re-examined. Thanks to new technical means (software) and the investigative experience acquired over all these recent years, this re-examination sometimes leads to new remarks or even a change in classification explained in an investigation note. This case is consistent (two witnesses, including a police officer), the description of the observed UAP is very precise. The sincerity and credibility of the witnesses have never been questioned. The described phenomenon presents many common characteristics (observation duration, shape, size, color) with a perfectly known astronomical object: the Moon at setting. Furthermore, the Moon was indeed present in the area of sky observed while the witnesses do not mention it. It is not the visual perception of the witnesses that is at issue, but the interpretation that the witnesses make of their observation through their feelings (fatigue, night driving, Moon seen intermittently through the clouds). In the current GEIPAN classification, this case of low strangeness is classified as UAP A, observation linked to a misidentification with the Moon.
