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 Griesheim-près-Molsheim, on September 15, 2012:

Case number:



In March 2014, I found on a UFO website a short UFO sighting report by "Dididou" stating on that on September 15, 2012, at 09:50 p.m., on the highway with another person, they viewed "like an orange constellation " of a dozen orange yellowish balls that seemed much closer than the other stars in the sky.

As they were on the highway, the witness explained that he could not tell if the balls were moving. They disappeared after one another. The observation length was about 6 minutes.

09/15/2012 - (Dep.67) - YELLOW ORANGEISH BALLS

Date: 09/15/2012

Department: 67 (Bas-Rhin)


Time: 09:50 p.m.

Numbers [sic] of witnesses: 2 people

Type of observation: NL: Nocturnal Lights

Approxima [sic] duration of the observation: 6 minutes


Description of the facts:

Passing on the highway, we saw like an oranges constellation but that seemed much closer than the other stars in the sky, about a dozen balls. Being on the highway I can not tell if they were moving, but they disappeared one after another.




From the localization of the witnesses, I am tempted to suggest they saw one or more airplanes or helicopters landing at the airport of Strasbourg-Entzheim, as the runway is about 5 kilometers away only and right in the axis of the highway.

However, the description makes me think of the now very common Chinese lanterns that so often explain UFO reports in Alsace also in the 2000s.

Right: The place of observation, probably about the green dot, is almost in line with the Entzheim airport's runway.


Probable Chinese lanterns.
