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 Batzendorf, on December 21, 2014:

Case number:



A young man from Batzendorf in the Bas-Rhin who says his hobby is to observe UFOs begun to regularly report his observations of what he believes to be UFOs to the ufology web board "Les Mystères des OVNI" ("The Mysteries of the UFOs").

The report of his first observation, on January 10, 2014, indicates that on December 21, 2014, at 21:08, for 2 minutes, he would have seen in Batzendorf a "puzzling ufo phenomenon", a "flying object of round shape, with a strong brightness compared to a neon ", of yellow / white color.

He estimates that the object measured one meter, said that it was going "to the left" in straight line, that its trajectory was "North 35° - North 35°".

Invited 4 days later by a forum administrator to explain the progress of his observation, he did not answer.

Hello Aurélien

Thank you for sharing your observation with us

Can you tell us how your observation happened

Thank you for your answer




There is nothing clear enough to risk an explanation, but obviously several trivial explanations are possible. Note the lack of response to the request to report the process of observation.

The same young man testified just as poorly about another observation made the day after this one, report filed, this time, 3 days after the observation.
