ALSACAT is my comprehensive catalog of UFO sighting reports in Alsace, the region is the North-East of France, whether they are "explained" or "unexplained".

The ALSACAT catalog is made of case files with a case number, summary, quantitative information (date, location, number of witnesses...), classifications, all sources mentioning the case with their references, a discussion of the case in order to evaluate its causes, and a history of the changes made to the file. A general index and thematic sub-catalogs give access to these Alsatian case files.

Case of Mulhouse, on June 3, 1980

Case number:



In the 2000s, the French Luc Chastan published a web database of UFO observations in France.

He said he received a testimony by e-mail saying that an object passed at the vertical of the witness' home, 200 meters away from West to East.

It came very close to him, 30 meters for 15 seconds and left in the direction of Germany.

Luc Chastan indicates that the place is Mulhouse, the date June 3, 1980, and the time 5 a.m.

I recall that it is not possible to give a reliable distance with the naked eye for an object whose nature and therefore the actual size is unknown, seen against the background of the sky without a landmark providing a maximal distance.

If I understand correctly, at night, the person saw in the sky an object which he gives absolutely no description, moving silently or not in straight and this over a duration that may be of only 15 seconds.

It could have been almost anything: an airplane, a meteor, a bird, a flying saucer, what do I know?

To be fair, I admit that 30 meters is within the range of stereoscopic vision and that the person was certainly puzzled enough to report it, so a trivial explanation is not necessarily the correct one.


Low strangeness, insufficient information.
