AUNAY SUR ODON (14) 13.04.1983

On 13 April 1983 between 22:45 and 23:05, 2 motorists saw what they described as a very high, intensely bright yellow-green ball, comparable in size to a handball, with changing brightness. Through binoculars it seemed to move rapidly up and down, never more than 40–50 cm from its initial position and always returning there; the source gives no reference distance for that estimate. The brightness became intolerable, so they stopped watching. The sky chart places Venus low above the horizon, below 5° elevation, at azimuth 300°, matching the viewing direction. Despite the witness description of great altitude, GEIPAN considers that Venus's brightness probably caused the impression.
