An account in Yvelines, France

Testimony in 2008 of an observation made in the years 1988-1990 (the witness no longer remembers the exact date (spring-summer 1988-1990). The date of 01/04/1988 is given arbitrarily. During the spring or summer of the years 1988-1990, three people arriving on their property are intrigued by the presence of a mark on the ground at the edge of a hedge. This circular mark is about twenty centimeters wide and comes from the flattening of the grass. The circle thus formed has an outer diameter of approximately 2 meters. This mark will remain visible for several months due to differential growth of the affected grass compared to the rest of the garden. Only one testimony will be collected. This is a testimony that cannot be used by GEIPAN. Indeed, it does not describe a UAP (unidentified aerospace phenomenon) but a circle on the ground with no possibility of linking it to a UAP because no UAP is described. GEIPAN classifies this case as C: lack of information.
