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.

Latest reported cases

Here are the latest cases of unexplained phenomena reported to Alsatian ufologists such as Patrick Gross, Christian Comtesse or Christian Morgenthaler.

[... other cases...]

In April, June and October 2005, the same phenomenon (always a large luminous triangle) was spotted respectively above Schirmeck, south of Strasbourg and in the surroundings of Mulhouse.

Note: "same phenomenon" refers not to a "luminous triangle" but to a triangular dark mass with lights at the corners and the center.



Totally insufficient information.

I can only say that I am not the one of the three ufologists cited who would have been seized of this case.
