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 in Alsace, in 1989:

Case number:



In 2020, in the comments of a video lecture about "triangular UFOs" posted on Youtube, there was a testimony of a "triangle with 3 red dots and further on an orange ball in static in the Alsatian sky in 89".

The witness said he had "no coherent interpretation" of what he saw, and never saw again, but seems to think of a terrestrial "craft" because of the "symmetry" "in the design" and because it had a "pointed front end" that would be a sign of an origin from a "world where aerodynamics were also important."

xx/xx/1989 - Alsace

Posted by "JoŰl Tardio" in January 2020

Already seen the triangle too with 3 red dots and further on a static orange ball in the Alsatian sky in 89, it is important to cross-check this. I don't have a consistent interpretation of what I saw other than I never saw it again. What we can notice is the symmetry common to our species in the design of vehicles and the fact of carving the front end as if it inherited from a world where aerodynamics were also important. It's not nothing like similarities with our species. I'll let you think about it.


Without a precise date, without a precise place and with very little information, nothing certain can be said about this report.

However, it is possible that the witness was wrong by one year and that it was the famous re-entry into the atmosphere above Alsace among other places, of the debris of a Russian rocket.

A number of witnesses did indeed believe that it was not space debris, nor an extraterrestrial craft, but one or more "secret craft" most often believed to be American - an explanation that does not makes no sense at least in the case of the observations of that November 5, 1990.

At a certain time in the trajectory of this debris, and in particular over Alsace, the description was indeed of three lights - necessarily forming a triangle, and of another light less close.


Possible November 5, 1990 space junk.
