The Zonza Dark Mass

At about 5am on 28 August 2014 a man crossing a campsite near Sainte-Lucie de Porto-Vecchio, in the commune of Zonza in Corsica, watched a huge black circle with lights at its centre drift silently towards Sardinia. Rows of smaller dark shapes went before it and after it. GEIPAN investigated on the ground and could not explain it. This is the record of what one witness reported, not a verdict on what crossed the sky.

◆ THE SHORT VERSION

  • The Zonza Dark Mass is a reported UAP case in Sainte-Lucie de Porto-Vecchio, Zonza, Corse-du-Sud, France, 28 August 2014.
  • A lone witness crossing a Corsican campsite before dawn described a huge black circle with a ring of four to eight lights at its centre moving silently across a clear sky.
  • Rows of smaller dark groups, perhaps made of triangles, were said to travel ahead of it and behind it at the same slow pace towards Sardinia.
  • GEIPAN's investigator checked meteors, a satellite re-entry, aircraft, cloud, a disco's sky projector and ocular migraine, and scored every one very unlikely or nil.
  • GEIPAN classes the case D1, unexplained, of good consistency and medium to high strangeness.
  • For this case Fractured Realities holds 1 distinct source and 1 corroborating primary document.
  • The archive grades it L0 · SINGLE ACCOUNT — the archive holds one account of it, from a single source.

The heat woke him at about 4.30. He went out for air, spent a while on the campsite computer and was crossing the yard back to his bungalow at around 5am when he looked up. Between the trees, high in a clear starry sky, "un énorme cercle noir" (a huge black circle) was moving. Its rim was paler. At its centre four to eight lights formed a ring of their own. Ahead of it came two rows of smaller dark groups, perhaps made of triangles, and one or two more followed behind. Everything moved slowly and silently at one steady pace. It travelled in a straight line from the direction of Conca towards Sardinia. After about ten minutes it was too far away to see.

What is on the record

GEIPAN is the unit of the French space agency CNES that investigates unidentified aerial phenomena. The witness gave a statement to the gendarmerie the same day. In September 2014 GEIPAN sent an investigator. The interview and field inquiry confirmed the account, GEIPAN says. The investigation report works through six explanations. A meteor shower, a satellite re-entry, an aircraft and a disco's sky projector at Porto-Vecchio were each checked and scored very unlikely or ruled out. So were cloud and ocular migraine. Figari airport was closed at that hour and military radar showed nothing in the area.

GEIPAN classes the case D1: unexplained, of good consistency and of medium to high strangeness. It finds the case "d'une étrangeté certaine" (undeniably strange) but notes the movements showed no sign of intent.

Two loose ends remain. The witness said he briefly spoke to another man crossing the campsite who was also watching, but that camper was never traced. He also said the Moon lit the site well, while the report's own astronomical check says the Moon was not visible.

Why it sits where it does

L0 · SINGLE ACCOUNT. GEIPAN withholds the identities of its witnesses, so the released record carries no identified witness. The tier measures sourcing, not the quality of the investigation. What crossed the sky over the campsite is not resolved here.
