FLYING SAUCER OR SOUNDING-BALLOON?
Extraordinary coincidence: an exactly comparable object was observed in August and September in the Creuse (See on page 9).
this is the "unidentified object" which was photographed in the sky of Sainte-Geneviève, May 8, around 5 p.m.. The picture was taken at the 1/75th on a standard 210 mm telescope.
Note: it is indeed a balloon and not a flying saucer.
