Sighting in Ouessant, April 29, 2010

At 11 p.m., three people carrying out maritime surveillance as part of their work noticed a light moving across the sky. They were on the gallery of a tower overlooking the ocean, facing the sea. Photographs were taken, some of them through an observation telescope.

All three witnesses confirmed how long the phenomenon lasted, what it looked like, its path, and that it appeared in a very specific part of the sky, which gives the case very strong consistency. The investigation found that most of the characteristics described (path, speed, duration) match those of planetary motion. The strong brightness of a single point of light, similar to artificial lighting, is typical of the planet Venus. The strangeness of the phenomenon was rated as low. It was checked that Venus was in the observed area throughout the observation, a hypothesis regarded as certain and well verified. GEIPAN therefore classified the case as A: observation of Venus.
