The Walker's Light at Maffliers

His dog noticed it first. At about 6.06 on the morning of 29 June 2012 a man out walking near Maffliers, in the Val-d'Oise north of Paris, looked up to find a white luminous object stationary at low altitude over a field at the edge of a forest. He watched it for less than twenty seconds. In that time he judged it very large, flat underneath and concave on top. Rain began to fall. The object rose a little, tilted and left at high speed towards the clouds. He heard nothing and saw no smoke, and he was frightened.

What is on the record

GEIPAN is the unit of the French space agency CNES that investigates unidentified aerial phenomena. It holds this case as MAFFLIERS (95) 29.06.2012 and classes it D1. Class D means GEIPAN investigated and could not explain what was seen. The released file includes the gendarmerie statement and 40 pages of investigation notes. The gendarmes had found flattened grass near the path but not under the object, and could not say whether people, animals or weather made it. The air gendarmerie had no air traffic over Maffliers, and a helicopter pass found nothing.

The obvious answer was the sun. GEIPAN calls the sighting "extrêmement semblable et synchrone" (extremely similar, and at the same moment) with a classic natural sight: the sun rising between two layers of cloud. Three things did not fit. The walker was looking 54 degrees away from the sun, a gap GEIPAN says cannot be put down to uncertainty. The tilt might be an illusion caused by the glare. The object also looked almost ten times the size of the sun's disc.

Investigators went to the site once to check his directions and ruled out an unintended error in his bearings. They went back to test a complex reflection of the sun and found no satisfactory hypothesis. They note the weather cannot be reproduced: great heat and heavy rain the day before, thick cloud that morning. Nobody else reported the light.

Why it sits where it does

L0 · SINGLE ACCOUNT. GEIPAN withholds the identities of its witnesses, so the released record carries no identified witness, and the case rests on one walker. The tier measures sourcing. It says nothing against an investigation that ran to two site visits. What the walker saw is not resolved here.
