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, a 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 sub-catalogs by topics give access to these Alsatian case files.
ALSACAT being just started, there is no subcatalogue yet.
