In recent days, motorists claimed to have seen, in the region of Morestel (Isère), a mysterious craf that must have landed near this locality.
However, the next morning, a farmer in a neighboring hamlet noticed that a strange device was in a field. What increased his surprise was to find that an intermittent light emanated from the device.
It was, in reality, a weather balloon with its recording devices which include light bulbs whose light would vary, it seems, according to certain temperature conditions.
The farmer sent the balloon and the device to the address indicated on the attached sheet, that is to say to the Trappes Observatory (Seine-et-Oise).
It is probably the luminous saucer seen the night before by motorists victims of an optical illusion.
