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.

The luminous dot seems to keep a constant brightness, whereas Chinese lanterns usually show some twinkling as their flame flickers. The luminous dot appears totally white, whereas Chinese lanterns show - most often - an orange coloring.

This is why I think it was probably a LED balloon.

Obviously July 14, the national day, is a good time to release this kind of thing.

LED balloons.


Probable LED balloon.
