On September 10, 2010 at 8:49 PM, a witness from their home is intrigued by the silent movement of a luminous phenomenon in the sky. Of average strangeness due to the possible succession of misidentifications of different origins, and of good consistency thanks to precise geographical landmarks on the sketch in 4.1, this observation case is explained for its first part by a misidentification with the passage of the International Space Station (ISS), hence a suggested partial classification as A. For the second part of the observation, it is necessary to introduce new hypotheses, namely a possible airplane with its approach lights on, or a perception illusion (perception of 2 straight segments instead of an arc of a circle). These hypotheses, not being able to be confirmed, will remain weak. This case is consistent (one eyewitness, with quality testimony), and its strangeness is low, since it is fairly well explainable with known phenomena. Given the uncertainty about the second part of the observation, this case is classified as "B": probable observation of the International Space Station (ISS).
Thanks to new technical means (software) and the investigation experience acquired over all these recent years, this re-examination sometimes leads to new remarks or even a change of classif…

A witness observes, on July 3, 2010, starting at 11:50 PM, the movements of a white luminous point in the sky that intrigues them. No particular noise is heard during the filmed observation.…
