Astronomy: the mysterious halo of the moon in the Charente sky fascinates CL readers

The mysterious phenomenon appeared in the Charente sky around 10:00 p.m. “The glowing circle disappeared in seconds”remarked Aurélie Martin.

No need to ask experts to understand what it was: CL readers who are used to seeing the sky and ripping books and specialized websites. In Roullet-Saint-Estèphe, Charlène Massonnaud shines a light on our lantern: it is one “photometeor”. Manuel Meslier in Châteauneuf concludes: “This phenomenon is due to ice crystals in suspension. »

A rare phenomenon

Here are some more detailed explanations: as beautiful as it is rare, this phenomenon, aptly called a photometeor, is really an optical illusion created by the refraction of light or reflection of ice crystals in the atmosphere.

The temperature drop observed on Monday evening has probably contributed to this. This type of phenomenon is sometimes observed around simple lampposts. The halo is of the same family as the rainbow or the green ray. In antiquity, observers associated it with a divine sign.
