CHINON (37) 1993

On 10 July 1993 at about 01:00, a witness saw a shapeless light rotating clockwise with a faint hum. He fetched his female friend, who also saw it and woke her mother, who observed it too. Gendarmes found 2 further witnesses, but they declined to give statements. The phenomenon recurred about every 20 minutes until 02:30, when the observers went to bed. It was not formally identified, but a laser beam from a nightclub about 10 km away is probable, given the cloud layer and viewing direction.
