SAINT-LO (50) 04.04.2012

On Wednesday 4 April 2012 at 20:15, a witness was intrigued by 2 yellow or white points of light moving rapidly across the sky from east towards north. The first followed a steady straight path. The second continually moved around it, tracing ellipses, making abrupt acute-angle turns, moving into contact and rapidly returning to a position behind it. The sighting ended after about 15 seconds when both lights disappeared through or behind a cloud. A field investigation clarified the azimuths; a cognitive interview added no significant new information. GEIPAN nevertheless considers the case highly unusual because of the second UAP’s movements around the first, and finds that ordinary misidentification hypotheses do not explain it (see the investigation report). The single brief account leaves the possibility of a temporary visual illusion, such as an ocular migraine or phosphenes. However, the witness appeared to have excellent vision and health and reported no similar previous effects. GEIPAN rejected that hypothesis for lack of supporting evidence. GEIPAN rates evidential support at 0.7, noting that there is a single witness, with no reservations expressed. It rates strangeness at 0.6 because the object moved nonlinearly but was distant. The case is consequently classified D1, unexplained.
