Sighting in Chozeau, June 15, 2011

Isère, Auvergne-Rhône-Alpes, France

Sighting on June 15, 2011 in Chozeau (Isère, France). According to GEIPAN, it was most probably a light from the ground (searchlight, laser, vehicle…) (class B).

What happened

The witness was filming a lunar eclipse when they noticed three luminous phenomena that puzzled them. While going over the video during editing, they found a fourth one. Examination of the videos and photos does not clearly support the account given.

At 3'48 in the footage, the first appearance coincides with a zoom-out: a bright point enters the frame that was not visible in the narrow field of view. When the zoom is increased again, the point appears to move back down. It is most likely a light source close to the ground, such as a nearby street lamp. At 4'02, another bright point appears below the Moon, and it is clearly a street lamp, part of whose post can be seen. The ephemerides show that the Moon was only 15° above the horizon, about two hours after moonrise.

The witness seems to have observed these phenomena only through the camcorder's viewfinder and then during editing, and the zooming in and out probably misled them. The photo showing two luminous "L" shapes corresponds to a long exposure, with camera shake, of two bright points, probably the same two sources captured on the video. GEIPAN classified the case as B: indirect observation, through video and photo, of street lamps on the ground.
