As its name suggests, 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 Oberhausbergen, on December 8, 1973:

Case number:



In a listing of UFO sighting reports in the Haut-Rhin on their website, the Alsatian ufology association SPICA noted around 2015 that on Saturday, December 8, 1973, in Oberhausbergen, a "luminous spot" was observed, and remained unidentified due to lack of information.

I found no other source.

information not communicated
Unsolved -lack of info


I do not exclude, given the lack of information and lack of source, that this would be in fact the August 8, 1973 case in Oberhausbergen, as it is missing from the [sp4] list.


Possible misdated, totally insufficient information.
