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.

About the climate of Alsace in the XIIIth century

The following facts are recorded in the Annales des Dominicains de Colmar, a work from the 13th century which constitutes one of the important monuments in the history of Germany in the Middle Ages, and which is, without a doubt, the capital document of the history of Alsace during the period to which it refers (1211 - 1308).

These notes are given according to the excellent edition of the royal library of Stuttgart, by Messrs. Gérard, lawyer at the imperial court of Colmar, and Liblin, director of the Revue d'Alsace (Colmar, 1854).


1287. -- [...]

On the seventh of the ides of August (August 7), during the night, two stars appeared, one of which was very large, and the other small; they suddenly brightly lit up the night, as if the sun were shining, then suddenly disappeared.


We can obviously think here that it was a meteor that would be broken into two fragments. There is not enough information, neither to make it a certainty, nor to rule it out.


Possibles meteors.
